This study investigates a suitable rotor structure of permanent-magnet-assisted synchronous reluctance motor (PMASynRM) with ferrite magnets for torque ripple reduction. In order to reduce noise and vibration, the torque ripple should be small. The effects of shifting the flux barriers of rotor on torque performance are examined, and a suitable rotor structure is proposed for reducing the torque ripple. The performance of the proposed PMASynRM is evaluated based on FEM and experiments, and it is confirmed that the torque ripple can be reduced without any reduction in average torque.
