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.

Bosch starts production of 800V inverter, motor for electric vehicles

Green Car Congress

In the 800-volt variant of the electric motor, Bosch has increased the power density. This reduces weight and allows for a more compact design. Due to the use of I-pin bar winding, the motor’s efficiency, compactness, and level of automation in production can be further improved. These increase efficiency, and thus also range.
