摘　　要：基于ＳＲ电机线性模型和定子振动简化模型，推导了ＳＲ电机径向力解析式，分析了ＳＲ电机定子振动特性和抑制振动的方法，在ＷｕＣＹ等提出的“两步换相法”抑制振动的基础上，提出“改进的两步换相法”，研究了电压ＰＷＭ方式振动抑制策略，并采用只有６只主开关的功率变换器，将改进的两步换相策略引入四相（８／６）ＳＲＤ设计中，实验表明，有显著抑制振动效果。The radial force between the stator and rotor in the SR motor has been analyzed based on the linear model and a simplified vibration model of SR motor,which has been used to draw conclusions about the vibration characteristic and the control technique to reduce vibration of SR motor.An adapted method to cancel the vibration in SR motors more effectively has been developed based on Wu C Y's technique whose commutation process is not one stage but two.Some expriement validation are given in this paper.
