定子极数减少了的改进型多相无刷电机
摘要：
一种A相无刷电极，其中A为大于或等于2的整数，包括定子和转子。定子具有q个定子极，其中q为大于或等于A的整数。定子极形成S个定子极组，每个具有A个定子极对应A相，其中S整数等于(q/A)。转子具有p个转子极，其中p为大于或等于2的整数，并且布置成转子极面对定子极。进一步，在无刷电机中，p≥q，并且定子极布置在电机的圆周方向，这样，在S个定子极组中每个中的A个定子极中的任意邻接的两个具有的电角度位置差等于(360°/A)。
摘要（英）：

An A-phase brushless motor, where A is an integer greater than or equal to 2, includes a stator and a rotor. The stator has q stator poles, where q is an integer greater than or equal to A. The statorpoles form S stator pole sets each consisting of A stator poles each of which corresponds to one of A phases, where S is an integer equal to (q/A). The rotor has p rotor poles, where p is an integergreater than or equal to 2, and is so arranged that the rotor poles face the stator poles. Further, in the brushless motor, p>=q, and the stator poles are arranged in a circumferential direction of the motor such that a difference in electrical angular position between any adjacent two of the A stator poles in each of the S stator pole sets is equal to (360 DEG /A).
