开关磁阻平面电机具有结构简单、运行可靠、控制方便等优点,在生产生活中应用广泛.然而其磁路特有的非线性结构,给电机的结构分析和控制方法带来了很大的困难.本文采用有限元分析方法,对开关磁阻平面电机结构分析,并运用Ansoft Maxwell 3D软件仿真.通过建立有限元模型,分析了开关磁阻平面电机的磁链以及电磁推力与动子位置的关系.研究结果为进一步开展开关磁阻平面电机的研究奠定基础.

Switched reluctance planar motor （SRPM） has many advantages such as simple structure, reli- able operation and easy control,and has found a very wide range of applications. However, non-linear structure of their unique magnetic circuits results in great difficulties of structural analysis and control methods. The structure of the SRPM is analyzed on the SRPM of flux, and the relationship between the electromagnetic force and the mover position.By the finite element method,Ansoft Maxwell 3D software and the establishment of the finite element model.Results lay a good foundation for further study on the plane,switched reluctance motor.
