摘　　要：借助Bertotti分离铁耗模型,结合Preisach磁滞理论,建立了通用的铁心动态等效电路。该电路模型充分体现了铁心材料的磁化特性和实际损耗,能精确的对电机动态铁耗进行分离,为深入研究电机的动态特性及控制策略提供了便利。以一台轴向磁通永磁无刷直流电动机为例,对上述等效电路模型进行了验证。Based on the Bertotti＇ s separated iron losses computational model and Preisach hysteresis theory, a dynamic iron core circuit model was presented , and it was applied to build the equivalent circuit of the core of induction motor, it was suitable to deduce the dynamic equivalent resistances of core losses. Using these equivalent resistances the dynamic core losses of induction motor was calculated and separated precisely. An axial permanent magnet motor was used to validate it.
