Transforming the Future of Motors: EFLOW's Miniature AFPM Technology

The demand for advanced motors is surging due to the growth of cutting-edge sectors such as robotics, drones, and satellites. Traditional radial motors, widely used for years, face limitations in energy efficiency, size reduction, and operational precision. Korean deep-tech company EFLOW has unveiled its next-generation miniature Axial Flux Permanent Magnet (AFPM) motors to address these challenges effectively.

Addressing the Limitations of Conventional Motors

As the fields where these motors are applied expand, there is an increasing need for greater miniaturization, efficiency, and precision control. Conventional radial motors have structural characteristics that hinder further performance enhancement. EFLOW's innovative pancake structure allows it to overcome these issues, achieving significant improvements in several key areas:

1. Improved Energy Efficiency

Electric motors account for a substantial part of global power consumption, raising demand for energy-efficient solutions. Traditional radial designs limit potential efficiency gains, making it essential to develop improved alternatives.

2. Miniaturization and Weight Reduction

The cylindrical shape of conventional motors contributes to a certain degree of thickness and weight. In applications where weight directly influences performance, such as extending flight times for drones or reducing launch costs for satellites, miniaturization is crucial.

3. Heating and Control Performance

Issues such as heat affecting continuous operation and cogging torque impacting control precision necessitate further improvements based on specific applications.

EFLOW has effectively transitioned from radial to pancake structures with its AFPM technology, leading to a new generation of compact, efficient, and high-output motors.

The Technological Innovations of EFLOW’s AFPM Motors

EFLOW's AFPM motors boast unique design and manufacturing processes, enabling the combination of miniaturization with high output and enhanced productivity. They stand out in the following aspects:

- Compactness and High Output

With the same output, EFLOW has achieved remarkable performance metrics:

• - Thickness: Reduced by 60% (from 120mm to 50mm)
• - Weight: Decreased by 30% (from 2.0kg to 1.4kg)
• - Torque Density: Doubled (from 8 kW/kg to 16 kW/kg)
• - Continuous Operating Temperature: Improved by +30℃, accommodating extreme environments from -120℃ to 150℃

- Manufacturing Innovation

By consolidating 40 complex components into a single mold, EFLOW has succeeded in cutting production costs by a massive 95%. Compared to traditional precision motors, EFLOW offers benefits such as a 55% lower price and reduced lead times (from 16-24 weeks to just 8 weeks).

- Total Solution Integration

While competitors often provide only the motor, EFLOW presents an intelligent total solution package, integrating the motor, drive equipment, and proprietary AI sensors all together, offering added value.

Market Expansion and Proven Achievements

Leveraging a common AFPM core platform, EFLOW is streamlining development efficiency and optimizing R&D costs while expanding its product offerings across various fields, including mobility, drones, robots, and satellites:

1. Mobility: EFLOW has supplied products to over 25 BtoB clients, achieving a 98% repeat order rate, with promises of long-term supply exceeding 7,500 units to electric mobility makers in Spain.

2. Drones: Orders for 20,000 units are secured from a German client, with mass production set to commence in September 2026.

3. Robots: Currently in development with a major Korean electronics company focused on wearable robotics, targeting a 750W class AFPM motor.

4. Satellites: An AFPM motor designed for CubeSats has now been completed, resilient to the harsh conditions of space.

Additionally, EFLOW is participating in the supply chain for micro-mobility with Korean automotive manufacturers and has engaged in a three-year PoC and joint development with a leading aerospace company in Europe.

Strong Patent Barrier

EFLOW has established a robust business structure grounded in unique manufacturing technologies, intellectual properties, and system solutions, holding a portfolio of 84 patents across South Korea, China, and the United States. Furthermore, an FTO (Freedom to Operate) assessment ensures no risk of infringing upon third-party intellectual property rights.

Future Global Strategies and Vision

With a global team of 24 members, mainly based in Korea and Germany, each with over 30 years of experience in sales, design, and manufacturing, EFLOW is harnessing its expertise for growth. Currently in a Series A funding round aiming for 18 billion won, funds are earmarked for R&D hiring, facility enhancements, and mold infrastructure.

Plans include establishing a European production hub in 2026 and expanding operations to North America by 2028 while strengthening the Asian market. EFLOW also aims to enter KOSDAQ by 2029 and broaden its global presence in the AFPM motor sector.

As interest in AFPM motors increases in the Japanese market, inquiries and collaboration opportunities are being managed by JASP Corporation, located in Chiyoda, Tokyo, which supports the distribution and technological assistance for EFLOW's AFPM motor technologies.
