摘　　要：开关磁阻电机(SRM)特殊的结构使建立其磁链模型比较困难。根据SRM运行的周期特点,从数学角度用傅里叶级数模型对其进行解析,通过权系数将傅里叶级数模型与传统指数模型结合,得到一个新的改进模型。用提出的改进模型与指数函数模型、傅里叶级数模型分别对Ansoft Maxwell仿真得到的磁链数据进行拟合。对比解析结果,证明提出的改进模型具有更高的解析精度,适合解析磁链。The special structure of switched reluctance motor makes it difficult to establish its flux linkage model.According to the periodic characteristics of SRM operation,a model based on Fourier series is proposed from the mathematical relationship.By combining Fourier series model with traditional exponential model through weight coefficient,a new improved model is obtained.Using the improved model,exponential function model and Fourier series model,the simulation flux data of Ansoft Maxwell are fitted respectively.By comparing the analytical results,it is proved that the improved model has higher analytical accuracy and is suitable for the analysis of flux linkage.
