摘　　要：针对两层磁障的同步磁阻电机,分析磁障厚度比例对磁阻转矩的影响。进而在优化的同步磁阻电机中间磁障中插入永磁体形成永磁辅助同步磁阻电机,讨论此类永磁辅助同步磁阻电机的齿槽定位力矩、永磁转矩、磁阻转矩和抗退磁性能。最后对比了同步磁阻电机和永磁辅助同步磁阻电机的转矩特性以及调速特性。With a two-layer flux barrier synchronous reluctance machine （ SynRM）, effect of the ratio of the two flux barrier thickness on the reluctance torque was analyzed. Then, permanent magnets （PM） were inserted into the flux barrier, forming a permanent magnet assisted synchronous reluctance machines （PMASynRM ）. Cogging torque, PM mutual torque, reluctance torque, and anti-demagnetization capability of the magnets were discussed for the obtained PMA-SynRM. Finally, the torque performance and the speed-adjusting performance of the SynRM and PMA-SynRM were compared.
