WebAug 13, 2024 · In , the main PMs can be moved to a new position under the centrifugal force, and the low air-gap flux is produced due to the effect of the non-magnetic conductor. Moreover, a spoke-type IPM machine with radially displaceable mobile yokes is proposed in [17-19]. At high speed, the increase of PM leakage flux leads to a reduction of the air-gap ... 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.
