Research on electromagnetic vibration and suppression of permanent magnet assisted synchronous reluctance motor

The characteristic of radial electromagnetic force and torque ripple of permanent magnet assisted synchronous reluctance motor (PMSynRM) under load condition was analyzed; considering to minimize the radial electromagnetic force and torque ripple, An effective and detailed method of suppressing vibration of PMSynRM was proposed. The validity of the proposed method is confirmed by both simulated and experimental results.
