All about electric motors with no rare earths
Summary
Renault Group outlines electric motors that do not use rare earth magnets, detailing three motor families (permanent-magnet synchronous motors, asynchronous/induction motors, and electrically excited synchronous motors) and highlighting the magnet-free EESM approach. The piece traces Renault’s EESM evolution from 2011 to the upcoming E7A generation, notes production at Cléon, and emphasizes strategic shift away from rare earth dependencies with an eye toward 800V architecture and higher efficiency.
