ZF High Revolution Drive development

Automotive supplier ZF has introduced its High Revolution Drive, an electric powertrain designed for high-volume passenger vehicles. The system is capable of reaching speeds of 30,000 rpm, which is a significant increase from the 18,000 rpm seen in the company’s existing Select platform.

By utilizing higher rotational speeds, the 3-in-1 unit, which integrates the motor, power electronics, and transmission, achieves a peak power of 200 kW and a peak torque of 3,500 Nm through a two-speed gearbox. This technical approach allows the unit to be approximately 25 percent smaller and lighter than comparable 18,000-rpm drives. Additionally, the design uses half the magnet mass required by previous systems, which may lead to a 13 percent reduction in costs and reduce industry dependence on specific raw materials.

The drive is compatible with both 400-volt and 800-volt architectures and maintains an energy conversion efficiency of nearly 93 percent. ZF reports that several automakers are already in discussions regarding the technology, with series production planned for 2030.
