Magnetic Field Analysis and Iron Loss Estimation of an SRM

本文采用有限元计算技术对四相开关磁阻电机（ＳＲ电机）磁场的磁场模式进行了分析研究，阐述了各部分铁心中磁场变化周期及规律，并借助谐波分析方法估算了电机铁心损耗。

The magnetic fields of a 4-phase switched reluctance motor (SRM) are analyzed with finite element Method. The frequencies and forms of the flux variations in different perts of the core are described. Fourier analysis is applied to estimate the iron loss of the SRM.
