Several companies around the globe have been hard at work innovating and refining magnet-free electric motors to make them a more viable option for the fast-growing EV industry. ZF Friedrichshafen has taken a similar wireless inductive path to fellow German automotive supplier Mahle, but with its own unique configuration. By integrating its inductive transmitter into the rotor itself, ZF saves space and creates a particularly compact magnet-free motor it says performs comparably to the permanent-magnet synchronous motors (PSMs) that dominate contemporary EV engineering.
