The most compact nonmagnetic electric motor] is develope

The German automobile concern ZF Friedrichshafen AG developed the most compact in the world the nonmagnetic electric motor I2SM which works not worse than synchronous motors with permanent magnets. In the future company integrates it into power plants on 400 and 800 V for producers of automobile and cargo electric cars. Contactless induction — one of ways to direct electricity on coils a rotor without brushes or rings. Developing this concept, experts of ZF Friedrichshafen AG integrated the inductive sensor in a rotor axis in the middle of coils, having reduced space by 90 mm without decrease...
