基于Ansoft的汽车开关磁阻电动机仿真分析

Simulation and Analysis of Switched Reluctance Motor Applied in the Automobile Based on Ansoft

利用Ansfot公司的Maxwell2D瞬态模块,建立了三相6/4结构的汽车用开关磁阻电动机(SRM)模型,设计了外加电路,构建了一个完整的仿真系统。通过对SRM模型瞬态有限元分析,得到了绕组磁链-电流曲线,同时得到了转速、转矩和相电流曲线。仿真结果精确地反映了SRM起动过程,为SRM优化设计、减少转矩脉动、提高起动转矩提供了理论依据。

The instantaneous model of three-phase-6/4-type switched reluctance motor has been set up using Maxwell 2D produced by Ansfot company in this paper. A complete system including additional circuit is designed and the simulation of this system has been done. It can be found that the result of the simulation accords with the starting process of SRM . The results of simulation can be benefits for the design of Switched Reluctance Motor and its control system.
