摘　　要：在考虑开关磁阻电动机(SRM)的转子位置角和电流对电感曲线影响的基础上,提出一种开关磁阻电动机的非线性电感模型,根据此模型解析计算了电机的相电流、电磁转矩和径向力.计算结果表明,该电感模型在SRM设计阶段,在不降低SRM力能指标的前提下,可减小径向力,从而为抑制振动提供理论依据,对SRM转矩脉动、振动噪声抑制策略的研究具有一定的意义.In consideration of the influences of rotor angle and phase current on inductance curve, a nonlinear inductance model of switched reluctance motor （SRM） was developed. With the model, the phase current, electromagnetic torque, and radial force were calculated. The calculated results show that, without degrading the force performance, the model can reduce radial force during the design stage of SRM, and thus it provides a theoretical basis for vibration depression. The model is of certain significance to minimization of torque fluctuation and reduction of vibration-induced noise.
