Electric Motorcycle Hub Motors

High-Velocity Engineering: The Evolution of Electric Motorcycle Propulsion

The transition from light e-bikes to full-scale electric motorcycles requires a fundamental shift in electromechanical philosophy. At HENTACH, formerly known as Hengtai Motor, we have spent the last 30 years mastering the high-torque, high-thermal-load environment of heavy-duty hub motors. Our Electric Motorcycle Hub Motors are not merely upscaled bicycle motors; they are ground-up engineering marvels designed to handle the rigors of highway speeds and sustained high-current draws. Operating within our 9,000-square-meter facility, our R&D team has developed a range of motorcycle-class drives that bridge the gap between urban commuting and performance racing. These motors are built using our 500-ton die-casting infrastructure, ensuring that the structural integrity of the motor housing can withstand the massive gyroscopic and braking forces inherent in a 150kg+ vehicle at speed.

Precision manufacturing is the heartbeat of our motorcycle series. Unlike smaller motors, a motorcycle hub must dissipate significant heat while maintaining peak efficiency. We utilize high-grade N42SH Neodymium magnets, which are rated for 150°C, and 0.35mm ultra-thin silicon steel laminations to minimize eddy current losses. This focus on material science allows our motors to maintain an efficiency peak of over 88%, even during aggressive acceleration. Our history in this sector is defined by our landmark durability tests. While the industry standard often stops at 10,000 miles, our motorcycle hubs were built to exceed the 50,000-mile mark. This longevity is achieved through our proprietary vacuum-impregnation of the stator windings, which protects against vibration-induced insulation failure and enhances thermal conductivity from the copper to the housing.

Furthermore, our motorcycle hubs feature reinforced axle geometries machined from 40Cr steel on our precision CNC centers. We understand that in a motorcycle, the motor axle is a critical suspension component. Our ISO 9001 certified process includes ultrasonic flaw detection for every axle to ensure no internal defects could lead to catastrophic failure. To protect these high-value components from the elements, we apply our signature Micro-Arc Oxidation (MAO) coating, which provides a ceramic-level barrier against the corrosive effects of road salts and high-pressure washing. For B2B partners, HENTACH offers a professional-grade powertrain solution that provides the silence of electric drive with the reliability of a 30-year manufacturing heritage. We don't just build motors; we build the future of two-wheeled transportation.
