     永磁同步电机的齿槽转矩对于电机正常运行的性能有较大的影响,它会影响电机运行时转速的稳定以及动态响应性能,因此齿槽转矩的分析一直是永磁同步电机设计的一个重点。而对于一些比较特殊的应用场合,例如永磁同步风力发电机,齿槽转矩的大小直接影响电机的起动性能,下图所示为某2WM(56极9.8Hz)永磁同步风力发电机的齿槽转矩波形。

       振动噪声问题是电机行业比较关注的热点,直接影响产品的品质和用户的舒适度。下图为某曳引机用永磁同步电机经频谱分析仪测试发现280Hz存在明显的噪声现象,本例采用有限元和振动噪声脚本的方法提取了该电机的径向电磁力频谱图,发现在280Hz频点存在电磁力且幅度较大,从而引起共振,形成噪音,确定了噪声的根源。通过磁极优化,280Hz频点的电磁力明显减弱,电磁力成份增多但幅值均较小,有效改善了噪声问题。 <
