已收藏BMG055NM230V后续依次c+a-、a-b+、b+c-、c-a+、a+b-、b-c+循环加电，转子磁铁就能循环转动起来了。每经过6次切换电流，转子转动一圈。
因为三个线圈相隔120°，所以，不难得出两个线圈同时导通时，转矩为单个线圈的√3倍。
上述驱动方法中，每次导通了两个线圈，因此称为“二二导通”驱动方式；相对地还有一种三个线圈同时导通的方式，称为“三三导通”驱动方式。
例如，施加电压为 a+b-c- 的状态时，由于三个线圈都会产生磁场，则定子磁铁会转动到下图位置（N极正对A线圈）：而且，由于A线圈中的电流等于B、C电流之和，所以总的转矩为1.5倍A线圈的转矩。
不难分析出，“三三导通”的驱动方式，也是6个步骤完成转动一圈。如我们依次按a+b-c-、a+b-c+、a-b-c+、a-b+c+、a-b+c-、a+b+c-循环控制线圈电压，则定子也能转动起来。
