摘　　要：该文主要分析了一种两相同时励磁的开关磁阻电机(SRM)的静态特性。文中首先简要介绍了这种两相励磁系统的结构,然后提出了两相励磁下SRM的磁链模型。基于详细的非线性有限元分析(FEA)的结果,建立了简化的线性模型且利用此线性模型导出了SRM的转矩——转角特性,并和非线性FEA模型下的结果进行了比较。最后,根据FEA的结果,提出了一种优化的控制策略来提高这种SRM的性能。This paper provides an analysis of a switched reluctance motor (SRM) under two-phase excitation. After a brief introduction of the two-phase excitation scheme, the flux linkage model of a SRM under two-phase excitation is developed using FEA. A linearized model is then established based on the detailed flux linkage analysis. The torque-angle characteristics of such a linear model are compared with that derived from the detailed and nonlinear FEA model. Based on the FEA model, an optimized control strategy is proposed to improve the performance of the SRM under two-phase excitation.
