ZF Makes Magnet-Free Electric Motor Uniquely Compact and Competitive

ZF has developed an electric motor which does not require magnets. In contrast to the magnet-free concepts of so-called separately excited synchronous motors (SESM) already available today, ZF’s I2SM (In-Rotor Inductive-Excited Synchronous Motor) transmits the energy for the magnetic field via an inductive exciter inside the rotor shaft. This makes the motor uniquely compact with maximum power and torque density. […]

Braided Windings & No Rare Earths in ZF 800-Volt e-Drive for Passenger Cars 

“Sustainable mobility is at the core of our corporate strategy,” says Stephan von Schuckmann, member of the ZF Board of Management responsible for electrified driveline systems. “Based on an extremely efficient production vehicle, we are showing the potential that future electric drive components offer when we combine them into an even more efficient overall system.” The technology is embodied in its EVbeat concept vehicle which is based on a Porsche Taycan and takes leading series technology from ZF and other market players as a benchmark.  […]
