摘　　要：为抑制开关磁阻电机(SRM)转矩脉动,从电机设计和控制的角度出发都需要快速、正确地获取其磁链和转矩模型。本文根据SRM磁链随角度、电流的变化特点,取6个特殊转子位置处的磁链数据,用七次多项式函数来建立SRM磁链模型和转矩模型,与有限元计算结果对比表明,所提方法具有快速和准确性。In order to restrain the torque ripple of the Switched Reluctance Motor （ SRM ）, the flux and torque model is needed to be quickly and accurately obtained in the point of view both from design and control. According to the characteristics of the flux＇s changes with the angle and current, flux dates of six special rotor positions were taken, a polynomial function with seven times was used to establish the flux model and the torque model of SRM. Compared to the finite element results, the method proposed in this paper is fast and accuracy.
