WebJun 29, 2012 · IPM motors produce torque based on two different mechanisms. The first is permanent-magnet torque which is generated by the flux linkage between the PM rotor field and the electro-magnetic field of the stator. It is the same torque produced by SPM motors. IPM designs produce a second force known as reluctance torque.
