摘　　要：通过对比分析采用尖角型与圆弧型周向磁桥的两种同步磁阻电机的磁密分布、平均转矩、转矩脉动和应力分布,阐述该两种周向磁桥的适用场合。对于多层磁障的转子结构,分析径向磁桥的位置与数量对电机电磁性能和机械性能的影响,进而总结权衡电磁性能和机械性能的径向磁桥优选规律。By comparing the flux density distribution, average torque, torque ripple and mechanical stress of rotors with rectangular and circular circumferential flux bridge ribs, respectively, this paper analyzed the ap- plication of the two circumferential bridge ribs in synchronous reluctance machine （SynRM）. For SynRM with multiple layer flux barriers, the impact of radial flux bridge rib position on electromagnetic performance and mechanical performance was investigated. Then, the selection criteria of the radial bridge rib position was concluded for the trade off between the electromagnetic performance and the mechanical performance.
