基于Ansoft12的小功率开关磁阻电动机仿真研究

摘要

近年来,小功率开关磁阻电动机(Switched Reluctance Motor,简称SRM)在小型电动车中(如高尔夫观光电动车、巡逻车等)的应用越来越广,本文基于Ansoft软件的RMxprt模块建立4相8/6极开关磁阻电动机模型,分析电动机在不同转子位置角时的磁场分布和绕组相电流、电磁转矩等静态特性.在此模型基础上,利用Maxwell 2D模块仿真电动机动态运行状态,分析电动机动态性能,仿真结果对小功率开关磁阻电动机在小型电动车上的应用有一定的参考作用.%Low-power switched reluctance motor(SRM) has been widespreadly used in small electric cars such as golf tourism electric cars, patrol cars, etc. The paper presented a 4 phases 8/6 poles switched reluctance motor model by RMxprt of An-soft, and analysed the motor static characteristics including magnetization curve at the various rotor position, phase current and electromagnetic torque. The dynamic performances of switched reluctance motor were simulated based on the model by Maxwell 2D, and the results of simulation are useful for applications of low-power switched reluctance motor in small electric cars.
