ZF unveils high-speed electric motor for EVs

Automotive supplier ZF has introduced the High Revolution Drive, a new electric propulsion system capable of reaching speeds up to 30,000 rpm. By increasing the motor speed, the system allows for a more compact and lightweight design without sacrificing performance.

Compared to existing solutions, the new technology occupies approximately 25 percent less space and weighs 25 percent less. Notably, the system requires 50 percent less magnetic material, which could reduce industry dependence on specific raw materials. The unit integrates the motor, power electronics, and transmission into a single assembly, capable of delivering up to 200 kW of peak power.

To manage the high rotational speeds and maintain quiet operation, ZF has optimized the coordination between the motor, gearbox, and bearings. The company is currently in discussions with several automakers and aims to begin series production by 2030. The system is designed to be compatible with both 400-volt and 800-volt architectures.
