摘　　要：本文讨论电机中铁磁材料的各种不同的磁导率。介绍了典型的凸极同步电机转子材料增量磁导率的测量结果，并给出了电机定、转子铁心典型材料的各种磁导率。文章最后还给出了应用不同磁导率计算变频器供电的同步电机运算电感的实例。This paper discusses various permeability's of ferromagnetic materials used in electric machines. The measurements of the incremental permeability of a typical rotor material of salient- pole synchronous machines are introduced, and various permeabilities for the stator and rotor of the machine are presented .As an example ,the operational inductance of a synchronous machine supplied by a cycloconverter is determined by the method described in the paper.
