摘要
针对凸极式同步推进电机的空载特性及其绕组参数与电机结构、定转子齿槽、磁场饱和等紧密相关的问题,分析了在不同励磁电流下同步推进电机相反电势的数值计算方法,提出了采用电机磁场能量微动法计算相绕组的参数,并对一台十二相同步推进电机的绕组参数及其空载特性进行了计算和测量。结果表明,提出的方法适用于分析多相同步推进电机的空载特性和绕组参数。
Considering the relations between idle load characteristics and armature winding parameters of the salient-pole propulsive synchronous motor （SPSM）with its structure ,stator tooth and magnetic saturation ,the analysis of numerical method for the back electromotive force calculation of SPSM is given under various exciting current values. Furthermore ,a method based on energy perturbation is proposed for the parameters calculation of armature winding,and it has been applied to the winding parameters calculation of a twelvephase SPSM as well as its idle load characteristics analysis, which indicate the validity of the proposed method.
