By Dr. Stan Trout | Spontaneous Materials A few months ago, I wrote an article called The Patent Challenge for the Spring 2015 issue of Magnetics Business & Technology Magazine. It was motivated by the […]
ZF has developed an electric motor which does not require magnets. In contrast to the magnet-free concepts of so-called separately excited synchronous motors (SESM) already available today, ZF’s I2SM (In-Rotor Inductive-Excited Synchronous Motor) transmits the energy for the magnetic field via an inductive exciter inside the rotor shaft. This makes the motor uniquely compact with maximum power and torque density. […]
