基于非线性模型的开关磁阻电机有限元分析

摘要

Study the magnetic field of switched reluctance motor by the finite element method. For the structure of switched reluctance motor is double saliency structure, the nonlinear magnetic field of switched reluctance motor is serious. The software Ansoft can get the magnetization curve clan of different rotor position, further seek inductance and torque characteristic curve. We combined the nonlinear simulation with finite element method and drew the simulation waveform. The result of our experiment proves the feasibility of nonlinear simulation and the rationality of finite element analysis data.%本文旨在运用有限元分析法研究开关磁阻电机磁场。开关磁阻电机具有双凸结构特性,所以其磁场呈非线性。Ansoft软件可得到不同转子位置下的磁化曲线族、电感及转矩特性曲线,再将有限元分析与非线性仿真有机结合,得出仿真波形。仿真结果可证明非线性仿真的可行性及有限元分析所得数据的合理性。
