摘　　要：以一款商业化的电机为基准,以基于有限元法的遗传算法为优化设计工具,并使用结构力学有限元校核设计了转子内薄弱区域结构,最终优化设计得到一款各方面性能均优异的永磁辅助同步磁阻电机。通过对比新设计电机与基准电机的效率云图和运行特性曲线,证实了新电机是一款可以直接替代基准电机应用的极具竞争力的新产品。A commercial machine as the benchmark was took, used the tool of optimization design method involvin~ ~enetic algorithm based on finite element method, meanwhile, applyin$ the mechanical finite dement analysis to check out the breakpoint of the rotor topology. Finally, obtained a PMa SynRM machine with great performance. By comparing the efficiency maps and operating characteristics of the new designed PMa machine and the benchmark, it＇s confirmed that the new machine was a competitive one which could be used to replace the benchmark directly.
