Introduction
Aura Systems, Inc. (“Aura”),
is a Delaware corporation founded in 1987. The Company innovated and commercialized the technology for Axial Flux Induction electric
motors and generators.
“Axial flux motors represent
a leap forward in motor technology, offering high efficiency, compact design, and lightweight construction. As industries continue to
push for more efficient technologies, the axial flux motor design is a promising solution that combines power, scalability, and superior
performance. Its ability to deliver energy savings while minimizing space and weight is likely to propel this motor design into wide use
across many sectors, shaping the future of motor-driven systems .” 1
Aura’s axial flux induction
motor technology (“AAFIM”) provides an industrial solution that does not use any permanent magnets, no rare earth elements,
is smaller and lighter, uses (i) significant less materials (just copper and steel), (ii) provides very high efficiency, (iii) significantly
less copper, (iv) highly reliably and (v) does not require scheduled maintenance .
The industrial electric motor
market is expected to grow from an estimated USD 113.3 billion in 2020 to USD 169.1 billion by 2026, at a CAGR of 6.9% during
the forecast period 2 .
Electric motors are employed
in infrastructure, major structures, and industries all around the world. Each year, almost 30 million motors are sold for
industrial use alone 3 . Electric motors find application in a variety of equipment throughout industry. Common industrial
applications include: (i) compressors, (ii) fans and blowers, (iii) heavy duty equipment, (iv) HVAC systems, (v) pumps and (vi) machine
tools (lathes and mills, etc.).
The universal global trend
for electrification has created in addition to the industrial demand for motors a very large demand for motors used in electric transportation
for vehicles, planes, and boats (“EV”). In such applications, one or more electric motors are used for propulsion. Most
electric motors currently used for electric mobility employ high energy permanent magnets 4 due to their high efficiency and
small size. The magnetic material is usually sintered neodymium–iron–boron (NdFeB) made or processed in China.
It is expected that over 100
million electric motors will be required per year by 2032 to meet the demand for the growing EV market 5 .
San Global Research 2024 stated
“Various motor types, including the switched reluctance motor (SRM), interior permanent magnet synchronous motor (IPM), induction
motor (IM), and switched flux motor (SFM), have been employed in EV applications. Among these options, the axial flux induction
motor (AFIM) stands out, drawing attention for its distinct advantages over conventional motors when integrated into EV systems .
The AFIM boasts superior power-to-weight and diameter-to-length ratios, compact construction, high efficiency, optimal utilization
of active materials, and enhanced ventilation and cooling. These unique features position the axial flux induction motor as a promising
and strategic choice, contributing to the ongoing evolution and improvement of electric vehicle technology.”
For Electric Vehicle applications,
AAFIM provide efficiencies that are equal to or higher than ones provided by the best high energy permanent magnet solution (“PM”).
AAFIM are smaller, have higher reliability, are more robust, have larger operating speed range, are not limited to 100 degrees C operating
temperature for the equivalent PM machine. In addition, AAFIM costs are significantly lower than the equivalent PM machines.

The history of electric machines
reveals that the earliest machines were, in fact, axial flux machines. However, after the first radial flux machines were demonstrated
in the beginning of the 20 th century, radial flux machines were accepted as the mainstream configuration. The reason for shelving
the axial flux machines were multifold and can be summarized as follows: (i) strong axial magnetic attraction force between the stator
and the rotor, (ii) fabrication difficulties such as cutting the slots in laminated cores, (iii) high cost involved in manufacturing the
laminated stator core, (iv) difficulties in assembling the machine and keeping a uniform air gap and (v) providing a laminated rotor that
can withstand the large centripetal forces.
In recent years there has
been great interest in axial flux topology for numerous industrial, commercial, and electric mobility motor and power generation applications.
However, to date the commercial focus in axial flux motors has been designs using rare earth permanent magnets (“PM”).
Nearly all the supply chain
for rare earths is concentrated in China and the chemistry associated with processing rare earths is challenging, expensive, and hazardous.
Reliance on China for raw material and magnet production, can influence global markets through (i) production decisions and (ii) geo-political
decisions by the Chinese government.
The extraction of rare earths
“ produce mountains of toxic waste. For every ton of rare earth produced, the mining process yields 13-kg
of dust, 9,600-12,000 cubic meters of waste gas, 75 cubic meters of wastewater, and one ton of radioactive residue. This stems from the
fact that rare earth element ores have metals that, when mixed with leaching pond chemicals , contaminate air,
water, and soil. Most worrying is that rare earth ores are often laced with radioactive thorium and uranium, which result
in especially detrimental health effects. Overall, for every ton of rare earth, 2,000 tons of toxic waste are produced. 6
On
April 15, 2025, China has restricted the export of several crucial rare earth minerals to the United States in response to President
Donald Trump’s tariff increases. China has used its rare earths monopoly as a weapon before, notably against Japan in
2010. In September of that year, the Japanese coast guard arrested the captain of a Chinese fishing boat that collided with Japanese ships
off the cost of the disputed Senkaku Islands. China retaliated by choking off Japan’s supply of rare earth minerals. Japan quickly gave
in and released the fishing boat captain, but it still suffered significant economic damage from the rare earths blacklist for years
to come. 7
A significant reason for industry
passing on Axial Flux Induction solution and focus on a PM solution could potentially be attributed to page 6 in Jacek F
Gieras book, where they pointed out that it is “ difficult to manufacture a laminated rotor with a cage winding for an axial
flux machine. If the cage windings are replaced with nonmagnetic high conductivity (Cu or AL) homogenous disk or steel disk coated with
Cu layer, the performance of the machine drastically deteriorates.”
Aura Systems with its
axial flux induction technology solved the issues related to the rotor back in 2002 and has shipped over 11,000 axial flux induction machines
in the 5-15 kW range to numerous military and commercial users . Aura’s proprietary rotor does not require any laminates
and provides the structural integrity to withstand very large centripetal forces while, at the same time, providing the proper electric
and magnetic properties without the usual issues associated with a solid rotor or a steel disk coated with a copper layer.
Aura has during the
last few years optimized its axial flux induction machine technology (no PM) where the performance (efficiency, torque, energy density)
is now equal to or greater than the very best of both axial and radial permanent magnet machines. Of course, this is done using only copper
and steel with aluminum for housing at a fraction of the cost of equivalent PM machines.

Aura’s Axial Flux Induction
technology is the culmination of decades of cutting-edge electromagnetic research and more than $150 million in development by Aura scientists
and engineers. Aura’s axial flux induction technology used for mobile power generation was first used in a combat zone by U.S. forces
in the U.N actions in the Balkans and since then, the U.S. military has used it in combat zones in both Iraq and Afghanistan. To date
the Company shipped over 11,000 systems for mobile power applications in the 5-15 kW range of which over 3,000 systems were for various
military applications.
Aura’s Axial Flux Induction
Machine has inherited advantages such as (i) no rare earth or any other kind of permanent magnets, (ii) significantly less copper (60%
less) than equivalent traditional radial flux induction motors, (iii) significantly higher energy density, (iv) fewer overall materials,
and (v) high efficiency. In addition, being an induction machine, Aura’s solution does not have any brushes or commutators and therefore
do not have any potential for sparks.
Aura’s Axial Flux induction
(“AAFIM”) Competitive Edge
○
Performance- AAFIM provides the highest power density across all other known motor technologies with energy density of more than 45 kW/liter for machines in the 250-kW range. In addition, Aura’s solution provides efficiencies that are higher than any other solutions for commercial and industrial applications. For 250 kW EV applications Aura’s designs show efficiency of more than 97%. AAFIM solution also has significantly lower rotor inertia than other solutions. This increases the machine efficiency even further since it requires less input torque to move the rotor.
○
Size and weight-Aura’s solution is significantly smaller in volume and has lower weight than any known solution for equivalent power rated machines (even includes PM machines). When compared to traditional radial flux (“RF”) induction machines, AAFIM has less than 40% of the weight and more than 40% reduction in volume. The AAFIM pancake design creates a solution that can be integrated with vehicles and boats for seamless exportable power.
○
Cost-AAFIM provides a significant cost advantage over equivalent induction and PM machines. The cost advantage comes from (a) the higher energy density which means less materials and (b) in the case of PM machines significant cost advantage for equivalent machines by just elimination of the permanent magnets. When compared to radial flux induction, Aura’s solution uses approximately 60% less copper. Due to the fractional materials used and the simple manufacturing processes Aura’s high-performance machines are less expensive to manufacture than other equivalent machines.
○
Other Advantages-Aura’s solution is extremely reliable with the only components to wear out are the bearings. AAFIM do not require any scheduled maintenance, and the only materials used are copper and steel for the active components and aluminum for the housing. These materials are readily available everywhere and are not controlled by any country or political group. In addition to the performance, Aura’s rotor lends itself to mass manufacturing. Many of Aura’s axial flux induction machines have been operating for twenty years and have shown remarkable reliability.
Our recent efforts have resulted
in our new 10 kW mobile power generator that which is approximately 20% smaller in diameter and 10% smaller in axial length than the legacy
8.5 kW solution. This new 10 kW has generated interest from the US military. We completed the design and fabricated a prototype of a 250-kW
axial flux motor which has approximately the same dimensions as our legacy 8.5 kW mobile power solution and is oil cooled. This new 250
kW motor has a base speed of 5,000 rpm and an operating range of up to 20,000 rpm. We have also completed the design and started fabrication
a 250-kW generator that is air cooled and will operate at 3600 rpm. We already have interest for this new 250-kwgenerator from Israel,
South Korea, and others. We recently completed the designs for a 5-horsepower motor for swimming pools applications and a 10-kW motor
for farm irrigation applications. Both of those motors will be put into production in the next few quarters
In March 2019, stockholders
of the Company represented a majority of the outstanding shares of the Company’s common stock delivered signed written consents
to the Company removing Ronald Buschur, William Anderson and Si Ryong Yu as members of the Company’s Board and electing Ms. Cipora
Lavut, Mr. David Mann, and Dr. Robert Lempert as directors of the Company in their stead. Because of Aura’s refusal to recognize
the legal effectiveness of the consents, in April 2019 the stockholders filed suit in the Court of Chancery of the State of Delaware
pursuant to Section 225 of the Delaware General Corporations Law, seeking an order confirming the validity of the consents. On July
8, 2019 the Court of Chancery entered final judgment in favor of the stockholder plaintiffs, confirming that (a) Ronald Buschur, Si Ryong
Yu and William Anderson had been validly removed by the holders of a majority of the Company’s outstanding stock acting by written
consent (b) Ms. Lavut, Mr. Mann and Dr. Lempert had been validly elected by the holders of a majority of the Company’s outstanding
stock acting by written consent, and (c) the Company’s Board of Directors validly consists of Cipora Lavut, David Mann, Robert Lempert,
Gary Douglas and Salvador Diaz-Versón, Jr. See Item 3, Legal Proceedings for more information. Following this ruling by the Court
of Chancery, the newly confirmed Board of Directors terminated the employment of Melvin Gagerman, who had served as CEO and CFO of the
Company since 2006, and installed Ms. Lavut as President, Mr. Mann as Chief Financial Officer and Dr. Lempert as Secretary of the Company.

Business Arrangements
During Fiscal 2018 and Fiscal
2019, the Company’s engineering, manufacturing, sales, and marketing activities were reduced while we focused on renegotiating numerous
financial obligations. During this time, the Company’s agreements with numerous customers, third party vendors, and organizations
and entities material to the operation of the Company business were canceled, delayed or terminated. During Fiscal 2018, the Company successfully
restructured in excess of $30 million of debt.
Also, during Fiscal 2018,
the Company signed a joint venture agreement with a Chinese company to build, service and distribute AuraGen ® mobile power
products in China. Under the Jiangsu Shengfeng joint venture agreement, the Chinese partner owns 51% of the joint venture and the Company
owns 49%. The Chinese partner contributed a total of approximately $9.75 million to the venture principally in the form of facilities,
equipment, and approximately $500,000 of working capital while the Company contributed $250,000 in cash as well as a limited license.
The limited license sold to the joint venture, however, does not permit the venture to manufacture the AuraGen ® rotor;
rather, the joint venture is required to purchase all rotor subassemblies as well as certain software elements directly from the Company.
During Fiscal 2018, Jiangsu Shengfeng placed a $1,000,000 order with the Company including a $700,000 advance payment of which the Company
has failed to deliver product in accordance with the order received. On November 20, 2019, the Company reached a preliminary agreement
with Jiangsu Shengfeng regarding the return of $700,000 previously advanced to the Company. The preliminary agreement reached consists
of a non-interest-bearing promissory note and a payment plan pursuant to which the $700,000 was to be paid over an 11-month period beginning
March 15, 2020, through February 15, 2021. The preliminary agreement was subject to the JV continuous operation. However, starting in
January 2020 the JV was shut down by the Chinese authority due to the COVID-19 virus. In 2023, the JV was dissolved and liquidated.
As of February 29, 2024, the
unpaid balance of $700,000 was reported as part of notes payables – related party in the accompanying financial statements. The
$700,000 advance payment was from the JV of which Aura owned 49%). During Fiscal 2020, the Company recorded an impairment expense of $250,000
to fully write-off the Jiangsu Shengfeng investment due to the uncertainty of the operation. In 2023 the JV was dissolved and liquidated.
Recent Developments
In fiscal 2025 the Company
completed the design and fabrication of an oil cooled 250 kW electric motor prototype using axial flux induction and completed the design
for a 250-kW air cooled generator using axial flux induction. In addition, the Company filed 3 new patent applications related to an axial
flux induction machine and subassemblies.

Induction Motor Applications
Aura’s axial flux induction
machine can be used as either an electric motor or generator as described above. Due to the inherit advantages of Aura’s axial flux
induction machine, such as (i) no rare earth or any other kind of permanent magnets, (ii) significantly less copper (60% less) than equivalent
traditional induction motors (iii) higher energy density and (iv) fewer overall materials, we believe Aura’s axial flux induction
motor can be used across a wide range of industries and applications. Even a small percent increase in motor efficiency translates to
a very large market-wide savings of dollars per year. Since Aura’s axial flux motor designs are more efficient than equivalent radial
flux induction motors, we believe that with the proper financial resources, over time, the Company can capture a reasonable share of the
global electric motor market.
4
Electric motor are the main
users of electricity, accounting for approximately 53% of the global demand for electricity. Over 65% of the energy used to support electric
motors is used for industrial motor systems. 8 The increase in global electricity consumption, and the use of electrical equipment
and machines in different industries and the renewables sector are major factors driving growth in the electric motor market.
Aura’s machines
use approximately 60% less copper, are approximately 1/3 the size and weight and are more efficient than the equivalent traditional radial
flux (“RF”) induction machine.
When compared to radial
and axial flux permanent magnet machines, Aura machines are less expensive to manufacture, do not use any rare earths, do not use any
permanent magnets, are not dependent on supply from China, are more robust, have a higher operating speed range, have lower maintenance,
have a longer lifetime, and are generally smaller, lighter and higher in efficiency.
EV applications
The
universal global trend for electrification has created in addition to the industrial demand for motors also a very large demand for motors
used in electric transportation for vehicles, planes, and boats (“EV”). In such applications, one or more electric motors
are used for propulsion. The power to drive the electric motors is generally a battery system or fuel cell. Both batteries and fuel cells
convert some form of fuel to electricity through some chemical process. EVs include, but are not limited to, road and off-road vehicles,
surface and underwater vessels, electric aircraft, and electric spacecraft.
In addition to the batteries,
the electric motor and supporting power electronics are critical components of EV drivetrain. It is expected that over 100 million electric
motors will be required per year by 2032 to meet the demand for the growing EV market 9 (where would all the rare earths come
from to support 100 million motors per year?).
The global Electric Vehicle
Market size is projected to grow from 4 million units in 2021 to 34.76 million units by 2030. 10 The AC motor (most power
by alternating current) is expected to witness the fastest growth in the electric motor market during the forecast period.
There are several key performance
metrics for electric motors. Power and torque density enables improved driving dynamics in a smaller and lighter package, with weight
and space being at a premium in EVs. Another critical area is efficiency. Improving efficiency means that less energy stored in the battery is
wasted when accelerating the vehicle, resulting in improved range from the same battery capacity. Smaller motor system weight will also
contribute to increase in range since less weight needs to be moved.
Most electric motors currently
used for electric mobility employ high energy permanent magnets. 11 The magnetic material is usually sintered neodymium–iron–boron
(NdFeB) made or processed in China. Neodymium is one of the rare earth elements. China has around a third of all rare earth reserves
and around 80% of global production. 12

In
1987 the Chinese President Deng Xiaoping famously said, “ the middle East has Oil; China has rare earths ”. An Oxford
Analytics Expert briefing on July 30, 2020, states that “(i) Permanent Magnets will account for 3⁄4 of rare earth demand by
2030 up from 1⁄4 in 2020 and (ii)Electric vehicles and offshore wind will drive demand and be most vulnerable to supply shocks” .
Permanent
magnet (“PM”) machines can be extremely light in weight and highly efficient. In PM machines the magnetic field B is fixed
by the magnets and the only way to change this is with a bucking field. These bucking currents result in an increase in temperature that
could affect the magnetization of the permanent magnets.
In PM machines the operating
temperature must be kept below 100 o C because at that temperature the magnets start to lose some of their magnetization and
at 180 o C they become completely demagnetized. However, in EV applications at low speed, one needs to use a lot of current (generating
high heat) to get the required torque; similarly, at high speeds one needs a lot of current for the bucking fields to reduce the B field.
Thus, PM machines for electric mobility require a very complex cooling system. All the components in the machine are designed for maximum
specifications but operationally the machine is limited by temperature requirements of the magnets. The cost of such machines is high
due to (i) The permanent magnets, (ii) the complex cooling system and (iii) complex controller.
Unlike the PM machines,
Aura’s axial flux induction machines do not use any permanent magnets and therefore the controller can change the B fields since
B is proportionate to the voltage divided by the frequency (V/f). Thus, the Aura machine, when operated with a smart inverter, has an
advantage over a PM machine. The Aura machine has a smaller volume, equal or better efficiency, more reliable and a large cost advantage.
This advantage becomes increasingly important as performance is increased .
Mobile and Remote Power Applications
The global generator sales
market was $20.3 billion in 2019 and is estimated to reach $27.16 billion by 2027 (Fortune Business Insight). Most industries dealing
with construction and infrastructure rely on mobile generators to support modern computers, digital sensors and instruments as well as
electrical driven tools. Current automotive alternators cannot supply the existing demanded power for many such applications and thus
the common solution is the use of stand-alone gensets (often referred to a “Auxiliary Power Units” or simply “APUs”).
These APUs, however, (i) consume large amounts of fuel, (ii) are heavy and bulky and accordingly must often be towed on trailers, and
(iii) require constant maintenance. Additionally, traditional APUs are generally not considered to be environmentally friendly power solutions
based on their high fuel consumption, loud operating noise levels, and the emissions they secrete into the air. In comparison, the
AuraGen ® system is small and light enough to generally be integrated directly into existing vehicles, does not require
maintenance, nor do they require any set-up or tear-down time. In addition, there is no heavy lifting required and to contact with hot
surfaces. The AuraGen ® operation when integrated in a vehicle or a boat is completely seamless and transparent to the user .
Beside stand-alone gensets
(often referred to “auxiliary power units” or simply “APU” s), all automotive users rely on integrated alternators
in their vehicles for such things as navigation systems, electric seating, electric windows, sound/ phone systems and lights. In 2019
alone, 87.9 million passenger vehicles were sold globally 13 (each one used an alternator). The market for automotive alternators
is presently dominated mainly by four companies: Denso, Valeo, Mitsubishi Electric, and Hitachi Automotive.
These companies jointly control
nearly 80% of the global market. The compact size and significant increase in efficiency of the AuraGen ® provides
an ideal replacement (fit and form) for high output automotive alternators while offering higher efficiency, longer lifetime and the flexibility
of multi types of voltage both AC and DC. Recently, the Company completed the design and development for a 10-kW alternator with a diameter
of 10 inches and axial length of less than 6 inches. The new 10 kW alternator will provide the full 10 kW power at alternator speeds of
2,500-13,000 rpm with efficiency higher than 90%.
The AuraGen ®
solution increase in efficiency over traditional generators, when combined with our load following architecture and the ability to provide
both AC and VDC simultaneously.

Competition
The Company is involved in
the application of its AuraGen ® technology to electric motors and mobile power. Therefore, it faces substantial competition
from companies offering different technologies .
Electric Motors
There are four (4) basic approaches
for electrical machines: (i) the rotor can be electrically excited such that it creates a magnetic field with constant orientation (as
in synchronous machines) that usually uses brushes and or commutators; (ii) the shape of the rotor can induce reluctance variations in
the stator (as in switched reluctance machines); (iii) the rotor can be permanently magnetized with permanent magnets (“PM “)
as in brushless DC machines; and (iv) the rotor field can be induced from the stator due to the rotor’s structure as in induction
machines. Our axial flux technology is an induction machine.
AC induction machine
(no PM) is the most common electrical machine in use today. A changing magnetic field in the stator induces a current in the rotor. The
current in the rotor produces its own magnetic field, which then interacts with the magnetic field of the stator, causing the rotor to
turn. The name induction comes from the fact that current is induced in the rotor by the changing magnetic field of the stator. Radial
flux induction machines have been the workhorse of industry due to their robustness, attractive cost, and ease of control; however, they
are relatively, heavy and bulky. On the other hand, Aura’s axial flux (“AF”) induction machines, have all of the advantages
of the radial flux machines but with the advantage of higher energy density and higher efficiency resulting in a smaller and lighter machine
with equivalent or better performance. Unlike the PM machines, induction machines do not use any permanent magnets and therefore the
controller can change the B fields since B is proportionate to the voltage divided by the frequency (V/f).
Although our axial flux induction
technology provides significant advantages in both cost (significant less copper, steel and aluminum), size/weight and performance, most
of our competitors have far greater financial, technical, and marketing resources than we have. They have larger budgets for research,
new product development and marketing, and have long-standing customer relationships.
Key players in the market
are (i) Nidec Motor Corporation, (ii) ABB Ltd., (iii) Siemens AG, (iv) WEG Electric Corp, (v) Regal Beloit Corporation, (vi) Wolong, and
(vii) Teco Westinghouse.
Generators
There are five basic approaches
used in mobile generators.
Gensets AKA APU .
Portable generators meet the large market need for auxiliary power. Millions of units per year are sold in North America alone, and millions
more are sold across the world to meet market demands for 1 to 20 Kilowatts of portable power. The market for these power levels addresses
the commercial, leisure and residential markets, and is essentially divided into: (a) higher power, higher quality and higher price commercial
level units; and (b) lower power, lower quality and lower price level units. Gensets provide the strongest competition across the widest
marketplace for auxiliary power. Onan, Honda, Generac and Kohler, among others, are well established and respected brand names in the
genset market for higher reliability auxiliary power generation. There are over 40 registered genset-manufacturing companies in the United
States.
Some of the key suppliers
are Caterpillar (US), Cummins (US), Rolls-Royce Holdings (UK), Atlas Copco (Sweden), Mitsubishi Heavy Industries, Ltd. (Japan), Yanmar
(Japan), Generac (US), ABB (Switzerland), Siemens Energy (Germany), Weichai Group (China), Kohler Co. (US), Kirloskar Oil Engines Ltd.
(India), Denyo (Japan), and Sterling & Wilson (India),
High Output Alternators .
There are many High Output Alternator manufacturers. Some of the better-known ones are Delco-Remy, Bosh, Nippon Densu, Hitachi, Mitsubishi
and Prestolite. All alternators provide their rated power at very high RPM and significantly less power at lower RPM. In addition, alternators
are generally only 30% efficient at the low RPM range and increase to 50% efficiency at the high RPM range.
Inverters. There
are many inverter manufacturers across the globe; the best known one is Xentrex. The pricing of industrial grade sine wave inverters is
approximately $400 per kilowatt plus the cost of a high output alternator (estimated at $1,000) and a good throttle controller (estimated
in the range of $250-500).
7
Permanent-Magnet Alternators. A
number of companies have introduced alternators using exotic rare earth Neodymium (NdFeB) magnets. These alternators tend to have higher
power generation capabilities than regular alternators at lower RPM. Unfortunately, PM machines with NdFeB magnets are very sensitive
to temperature and, unlike the AuraGen ® , cannot survive the typical under-the-hood environment (200 o F+). In
order to apply such devices for automotive applications one must add an active cooling system to keep the magnets from demagnetizing at
approximately 200 o F. In addition, most of the rare earth magnets (NeFeB) are manufactured in China and are subject to potential
political and economic pressure.
In addition to the temperature
challenges of such machines, there are other issues involving active control of the magnetic field. The main disadvantage of PM generators
is the difficulty of output voltage regulation to compensate for speed and load variation due to the lack of a simple means of field control.
Fuel Cells . Fuel
cells are solid-state devices that produce electricity by combining a fuel containing hydrogen with oxygen. They have a wide range of
applications and can be used in place of the internal combustion engine and traditional lead-acid and lithium-ion batteries. These systems
are generally more expensive. The most widely deployed fuel cells are estimated to cost significantly more per kilowatt than alternative
solutions.
Others
Evans Electric in Australia
has introduced an axial flux machine with a complete conductive rotor. Such a machine was first introduced by Brinner more than 20 years
ago and was abandoned because the rotor lacked the required rigidity to withstand the magnetic and centrifugal forces. The Brinner machine
is cited in Aura’s issued patents.
Numerous companies are introducing
axial flux machines; however, they generally use rare earth NeFeB magnets (made in China) and are thus not induction machines but rather
permanent magnet machines. Some of the better-known companies are YASA, EVO, Magnax and Phi Power.
Most of our competitors have
far greater financial, technical, and marketing resources than we have. They have larger budgets for research, new product development
and marketing, and have long-standing customer relationships. We also compete with many larger and more established companies in the hiring
and retention of qualified personnel. Our financial condition has limited our ability to market the AuraGen ® .
The AuraGen ®
uses a different technology and because our product is radically different from traditionally available mobile power solutions, users
may require lengthy evaluation periods to gain confidence in the product. OEMs and large fleet users also typically require considerable
time to make changes to their planning and production.

Competitive Advantages of the AuraGen ® Axial Flux
Induction technology
As a motor -Aura’s
Axial Flux (“AF”) induction motor/generator is increasingly attracting attention from high impact potential users seeking
advantages over conventional motors, particularly for Electric Vehicle applications. These advantages include (i) compact construction,
(ii) better power to weight ratio, (iii) shorter axial length, (iv) better efficiency, (v) better torque to volume and weight ratio, (vi)
very high utilization of active materials (less than 60% of the copper) and (vii) excellent ventilation and cooling. Induction machines
(i) do not use any rare earth elements and have no permanent magnets. Due to their flat shape, lower weight and compact construction,
Aura’s axial flux motors are ideal for pumps, fans, food processors, HVHC, etc. An axial flux machine is also preferred in applications
where the rotor can be integrated with the rotating part of mechanical loads.
The AuraGen ®
motor’s operational range is between -40 and 340-degrees F; therefore, it is suitable to operate in a harsh environment.
As an alternator.
Aura’s induction machine provides significant advantages in power generation, particularly in mobile applications. Its smaller volume
and higher efficiency, when combined with the geometric shape means it can be integrated with existing vehicles and boats. Such integrated
solutions do not require set up time. There are no heavy weights to lift (gensets), usable cargo space is optimized and there is no need
for separate fuel/containers. Remarkably, there is no scheduled maintenance required.
The AuraGen ®
alternator’s operational range is between -40- and 340-degrees F; therefore, it is suitable for operating under the hood of a vehicle
where the ambient temperature can easily be above 200 degrees F.

Technology . The AuraGen ® system is significantly more environmentally friendly than traditional motors and
generators. Because of its extreme efficiency and smaller size, the AuraGen ® system utilizes fewer resources and materials
to manufacture (in particular less than 60% of the copper). When used in power generation, the AuraGen ® uses a vehicle’s
primary automotive engine, which is already highly regulated for environmental protection. Traditional mobile power solutions, in comparison,
use small, less efficient, auxiliary engines that produce significantly higher levels of emissions per unit of power output than the automobile
engine.
Durability; No Scheduled
Maintenance . The AuraGen ® motor/generator solution does not require any scheduled maintenance. The historical
failure rate for Aura’s machines over a 20-year period is less than 0.5%. The bearings are rated for 28,000 hours.
Aura’s axial flux induction
(no PM) can be summarized as:
●
Disruptive since it addresses the entire field of electrical motors and generators by providing a solution that is smaller, lighter, more efficient, cost less to manufacture and does not use any permanent magnets .
●
Aura has demonstrated mass production of this technology with more than 11,000 machines.
●
The economic value proposition is well defined in terms of cost, performance and size.
●
The Aura solution provides significant global reduction in the use of raw materials such as copper, steel, and aluminum.
●
The higher efficiency of Aura’s motor, when used in a manufacturing environment, can lead to a noticeable reduction in the global consumption of energy .
●
When used for mobile power generation, Aura’s technology leads to a significant reduction in global pollution by being able to reduce and, in many situations, eliminate completely small diesel and gasoline engines used in power generation.
●
When used for electric vehicles, the smaller size, weight, and increased efficiency could lead to an increase in range and/or reduced battery weight .
●
When used in remote stand-alone diesel power generation such as cell towers, Aura’s increased efficiency, lower rotor inertia, voltages flexibility and load-following architecture results in a significant reduction in fuel usage (and, of course, reduced pollution).
●
Aura’s significantly (65% less) lower rotor inertia and variable speed capabilities make Aura’s solution ideal for small hydro applications that are currently being ignored because of construction cost, low head, and slow flow situations.
Targeted Market
The Company is re-examining
and identifying new key markets to focus on as the Company expands operations.

The global drive for electrification
is in search of better, more effective electric motors. The recent realization by many potential users of such motors that permanent magnet
motors are depending on NeFeB rare earth magnets from China has created a need for alternative to the PM motors. Our axial flux induction
machine is a solution that does not use any magnets and has the required performance characteristics as well as fit and form for numerous
applications.
Electric motors
Electric motors for
industrial applications. We have completed the design of 4 kW and 10 kW machines. The designs show significantly increased efficiency
as compared to equivalent other designs, and in addition they are a fraction of the size and weight, use approximately 50-60% less copper
and cost less to manufacture.
Electric motors for
high end electric cars. We now have a completed the design and fabrication of a prototype 250-kW axial flux induction (no PM)
with energy density of more than 45 kW per liter (the best other known design is approximately 40 kW/liter using rare earth permanent
magnets) and efficiency of more than 95%. Our design has an active diameter of approximately 9.45 inches and active axial length of approximately
4.92 inches.
Mobile power generation
Military market.
One focused market for the Company’s VIPER (military name for our axial flux induction generator) is military applications. While
traditional markets for military vehicles such as the U.S. are choosing to upgrade and maintain existing fleets rather than replace aging
vehicles, other regions are looking to purchase new units, which also provides maintenance and upgrade opportunities. The active number
of military vehicles was estimated at over 418,000 in 2021. New vehicle procurement is expected to decline in western defense and increase
in emerging markets of APAC and the Middle East.
Automotive alternators.
In 2019, 87.9 million units of passenger cars were sold globally, each one used an alternator. The market for automotive alternators is
dominated mainly by four companies: Denso, Valeo, Mitsubishi Electric, and Hitachi Automotive. These companies jointly control nearly
80% of the global market. The compact size and significant increase in efficiency of the AuraGen ® provides an ideal replacement
(fit and form) for high output automotive alternators.
Diesel based cell towers .
According to Statista (Technology and telecommunication Thomas Alsop sept 22, 2020), in 2019, there were 395,562 mobile wireless cell
sites in the United States, with a large amount of investment going toward 5G-ready cell sites and antennas as per the source. Phil Marshall,
chief research officer at Tolaga Research, estimates the global number of base stations at 6.5 million sites, while Chinese equipment
vendor Huawei puts the number at 7 million. Many of the cell sites are powered by diesel generators. The AuraGen ® solution
increase in efficiency over traditional generators, when combined with our load following architecture and the ability to provide both
AC and -48VDC simultaneously makes our solution very attractive to cell towers operators that depend on diesel power. Our solution has
the potential for significant diesel fuel savings in such an application.
Transport Refrigeration
(“TRU”) . The main competitors for the all-electric TRU are traditional diesel-based solutions provided by Thermo-king
and Carrier. The diesel based comparable systems provided by Thermo-king and Carrier are somewhat less expensive than our AuraGen ®
all-electric solution, however the diesel solutions require frequent maintenance and the utilization of a separate diesel engine
that consumes additional fuel every operating hour. In addition, the diesel solution emits harmful emissions that have been recognized
by the U.S. Environmental Protection Agency, California’s Air Resource Board and others as dangerous pollutants and are increasingly
subject to federal and state regulations. A CARB 2015 report “Technology Assessment Transport refrigeration” cites and provides
an analysis of our solution that can be applied for significant pollution reduction and fuel savings for truck-based transport refrigeration.
Facilities, Manufacturing Process and Suppliers
During Fiscal 2025, 2024 and
2023, the Company occupied approximately 18,000 square feet of space in Lake Forest, California. In early Fiscal 2022 the Company consolidated
all its administrative offices and operations into this new modern stand-alone facility. The Lake Forest facility is subject to a lease
agreement with a 66-month lease period effective from February 2021, through August 31, 2026. The monthly base lease rate for the Lake
Forest Facility is currently $24,239 per month with a 3% annual escalation. We expect to expand operations next year that will require
additional space.
10
As the Company continues to
expand its operations, we will need to renew relationships and contracts with our suppliers or locate suitable new suppliers for subassemblies
and other components.
Research and Development
We believe that ongoing research
and development is important to the success of our product in order to utilize the most recent technology, develop additional products
and additional uses for existing products, stay current with changes in vehicle manufacture and design and to maintain an advantage over
potential competition. Our engineering, research and development costs for Fiscal 2025 were approximately $1.2 million compared to approximately
$0.8 million in Fiscal 2024. In Fiscal 2025 we completed the design and built a prototype for a 250-kW electric motor using our axial
flux induction technology as well as completing the design for 250 kW electric generator using the axial flux induction technology. In
addition, we filed 3 new patent applications for our axial flux induction machines.
Patents and Intellectual Property
Our intellectual property
portfolio consists of trademarks, proprietary know-how, trade secrets, and patents. Historically the Company obtained 78 patents in electromagnetic
and electrooptical technologies. During fiscal 2025 the Company filed 3 new patent applications covering (i) new winding patterns can
be made to increase current density for increasing the torque density and the power density and (ii) two patent applications for the development
of novel cooling systems which make better heat dissipation is used to reach the highest torque and power density
The basic philosophy followed
by Aura is to build layers of defense to protect the Company’s IP. This is achieved through the development of fundamental patents
and surrounds them with application patents. The detailed fabrication of the rotor is kept as a trade secret since this is a critical
component in Aura’s proprietary intellectual assets.
The challenges of implementing
a patent philosophy are based on cost. Patent maintenance costs are expensive, particularly international patents. In order to maximize
a limited budget, our approach is to first file a number of new US patents. This will provide a year before international patents need
to be filed.
Government Regulation
We are subject to laws and
regulations that affect the Company’s activities, which include, but are not limited to, the areas of labor, intellectual property
and ownership and infringement, tax, import and export requirements, environmental, and health and safety. As we recommence operations,
our operations will again be subject to federal, state and local laws and regulations governing the occupational health and safety of
our employees and wage regulations. For example, we are subject to the requirements of the federal Occupational Safety and Health Act,
as amended, or OSHA, and comparable state laws that protect and regulate employee health and safety. We expect to expend resources to
maintain compliance with OSHA requirements and industry best practices.
Employees
As of the date of this filing,
the Company has a total of twelve (12) full-time employees in research and development, sales, operations and administration. Additionally,
the Company engages independent contractors, on an as-needed basis, to support various areas of the business. During Fiscal 2025 we engaged
three independent contractors to support engineering developments.
Significant Customers
In Fiscal 2025, one significant
customer, CBOL, accounted for 55% of revenues. In Fiscal 2024, one significant customer, CBOL, accounted for 55% of revenues, however
no customer is considered significant.

Raw Materials
The most important raw materials
we use in manufacturing our products are steel, copper, and aluminum. Raw materials are purchased both domestically and outside the United
States. We have no significant long-term supply contracts. When possible, we maintain a number of sources for our raw materials, which
we believe contribute to our ability to obtain competitive pricing. The cost of some of our raw materials and shipping costs are dependent
on petroleum cost. Higher material prices, cost of petroleum, and costs of sourced products could have an adverse effect on margins.
We enter into standard purchase
agreements with certain foreign and domestic suppliers to source selected products. The terms of these arrangements are customary for
the industry and do not contain any long-term contractual obligations on our behalf.
