ZF develops compact, competitive magnet-free electric motor: In-Rotor Inductive-Excited Synchronous Motor

Green Car Congress

ZF has developed an electric motor which does not require magnets. In contrast to the magnet-free concepts of separately excited synchronous motors (SESM) already available today, ZF’s I 2 SM (In-Rotor Inductive-Excited Synchronous Motor) transmits the energy for the magnetic field via an inductive exciter inside the rotor shaft.

MIT team developing 1MW motor for electric aviation

Green Car Congress

A team of MIT engineers is developing a 1MW motor that could be a key stepping stone toward electrifying larger aircraft. The motor under design is a 1-MW, air-cooled, outer-rotor, Halbach-array PMSM. The motor could then turn the electrical energy into mechanical work to power a plane’s propellers.
