摘要 埋入式永磁同步电机转子磁路结构与普通同步电机有很大差别,电感参数用传统计算方法难以准确计算。分别采用传统方法和保存与运行点相对应的磁导率的方法(fixed permeability method,FPM),利用Ansoft软件对永磁同步电机进行二维有限元计算,得到了电机的永磁体磁链λm、d、q轴电枢反应电感参数。分析了采用不同计算方法产生差异的原因,研究了饱和对埋入式永磁同步电机永磁体磁链λm、d、q轴电枢反应电感特性以及磁桥宽度对电感特性的影响。总结出埋入式永磁同步电机电感参数的变化规律,为永磁同步电机设计和性能分析提供了理论依据。 Since rotor structures of the IPMSM are different from the common motor, inductance parameters are hard to be accurately calculated by the traditional calculation method. A new analytical method, which is called the fixed permeability method (FPM), is used to calculate the inductance parameters and the magnet flux λm of IPMSM. The results calculated by the FPM and the conventional finite element method (FEM) are compared and the reasons which caused the different results are analyzed. The impacts of saturation and cross coupling on the inductance and the magnet flux λm and the impact of the width of the bridge on the inductance are studied. On the basis of the analysis, the influence factors and the rules of the inductance parameters of IPMSM are summarized, which are good for analysis and design of PMSM.
