Because very similar to chi shu rotors very few , the teeth harmonics moment for the second harmonics moment , and two stator mistaken 90e of mutual perspective , the two stator teeth resolved moment worth equal to 13 , 800 conversely , synthetic zero 3 .由于爪极数等于转子极数,故谐波力矩为2次谐波力矩,而2个定子相互错位90电角度,所以2个定子的谐波力矩幅值相等,相位相反,合成为零。
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 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。
