【摘要】 基于ＳＲ电机定子振动特性频域和时域实验结果，对角度位置控制（ＡＰＣ）和电压ＰＷＭ 工况下“两步换相法”的有效性及局限性进行了实验分析。研究表明，ＳＲ电机定子振动具有多个主振型，如何从总体最大限度地降低定子振动出发优化两步换相的时间间隔是值得进一步研究的问题；电压 ＰＷＭ方式斩波期间电流关断引起的冲击振动和位置换相引起的冲击振动一样，均可通过两步换相法抑制。但在斩波期间的每一斩波段采用两步换相法有一定的局限，当斩波频率设计值较高或电机固有频率较低时不宜采用。因此应进一步研究电压ＰＷＭ方式下振动抑制的策略．更多还原

【Abstract】 In a previous paper, a new commutation strategy for the reduction of vibrations of switched reluctance motors(SRM) was described. The commutation process of this new technique is not one but two. Based on experimental results the validation and limitation of the new strategy is analyzed. Since there are many modes for the stator vibration in SRM, the interval time between two stage of commutation process should be optimized to cancel the stator vibration. The vibration produced by a SRM with voltage PWM can also be reduced dramatically with the new commutation strategy, but it is not useful for high chopping frequency or low stator natural frequency.更多还原
