Axial Flux Motors for Electric Motorcycles - Benefits & Applications
As environmental awareness increases and the shift towards sustainable energy continues, the motorcycle industry is rapidly advancing towards electrification, smart technology, and high performance. The demand for electric motorcycles is on the rise, and their market share is expanding significantly. To meet the growing consumer demand for personalized experiences, future motorcycles will focus on enhanced performance, including faster speeds, more stable handling, and improved safety.
Our axial flux technology is at the forefront of these trends, significantly boosting the performance of electric motorcycles. This innovative technology provides manufacturers with a crucial competitive advantage in the rapidly growing electric motorcycle market. Explore how our cutting-edge solutions can drive your success in the evolving landscape of electric motorcycles.
Powerful Electric Motorcycle Motors for High-End Models
Our e-powertrain for electric motorcycles adopts innovative axial flux motor technology, delivering higher torque and output power while reducing kinetic energy loss and increasing traction efficiency. With the same motor diameter, our axial flux motor‘s power density is 3 times that of a radial flux motor, and its torque density is twice as high. When delivering the same torque and power output, our motor’s volume is reduced by 50%, and its weight is decreased by approximately 50%.
Additionally, our motor features a larger cooling surface and superior cooling performance, allowing for prolonged high-output power. Compared to radial flux motors, our motor’s peak power output capability is more than doubled.
In continuous operation, our 15 kW electric powertrain matches the power output of a 150 cc fuel motorcycle. It can operate at over 90% efficiency in more than 90% of conditions, resulting in lower energy consumption, better performance, and increased energy recovery. With our axial flux motor, motorcycle range can be improved by over 15%, without changing other components.
Moreover, even the 15 kW axial flux electric motor system weighs just 15 kg, significantly lighter than radial flux drive motors. Even with a side-mounted layout, it hardly affects the vehicle’s center of gravity. The side-mounted axial flux motor still allows the electric motorcycle to achieve a lean angle of 40 degrees, comparable to fuel motorcycles. This maintains the vehicle’s performance and range while preserving the joy of riding.

Benefits of Axial Flux Motors for Electric Motorcycles
Compact Design for More Powerful Performance
Compared to the commonly used radial flux motors, axial flux motors offer significant advantages. They can deliver multiple times the power within the same volume and weight or reduce volume and weight by more than 50% at the same power level. This means that electric motorcycles using our axial flux motors not only have significantly more power but are also more conveniently and flexibly arranged. For example, our 15 kW side-mounted electric motorcycle powertrain assembly, with a peak power of 15 kW and an axial dimension of less than 83 mm, is only about 1/3 the size of a radial flux motor of the same power.
Better Cornering Ability
In practical performance, the application of our axial flux motors allows the electric motorcycle to achieve a maximum lean angle of 40°, comparable to that of traditional fuel-powered motorcycles. The power tuning is highly refined, allowing precise torque output with small throttle adjustments within a turn. This ensures excellent cornering ability, on par with fuel-powered counterparts. Additionally, the acceleration response of the electric drive is faster, providing an enhanced riding experience.
Higher Torque for Superior Climbing Ability of Electric Motorcycles
Professional testing and analysis reveal that an ordinary household car can handle slopes of around 20°, while 4WD SUVs can manage up to 26°. Only a select few robust 4WD off-road vehicles can conquer slopes as steep as 30°. At a 26° incline, it becomes difficult for a person to maintain balance. However, an electric motorcycle equipped with our axial flux motor can easily perform a “half-hill start” on such slopes, thanks to its powerful 300 N.m wheel-end torque. When climbing hills, off-roading, mountain riding, or commuting, our axial flux motors for electric motorcycles help handle these challenges with ease.
