VR型步进电机定子磁极吸引转子时，由于转子磁极为**磁极，有磁化的N极和S极，不论定子绕组激磁所产生极性为N极还是S极均会产生吸引力。定子磁极激磁为N极时，吸引S极性转子磁极，激磁S极性的定子磁极会吸引转子的N磁极。定子磁极需要极性的切换。激磁定子磁极的线圈为单线圈绕组，磁极正反切换，则电流需正反向流因此驱动电路为双极方式。磁极上绕有两个线圈组成双线圈，一个线圈直流通电产生的极性，与另一个线圈直流通电产生的极性相反，此为单极方式。

今天我们在厂区换灯的时候看到一个同事打下空气开关后因为懒得拆线就用尖嘴直接把电缆剪断，你们认为这样剪电线是否正确。好像这样剪并没有错，空气开关都已经打下来了，平常很多人也都是这样剪，实际上这样剪线是比较危险的。有次我也在换一盏室外功率为55W的彩灯，因为原来的线是在灯壳里面接的，手上也有电笔但验不了电，除非把灯壳拆开。想想反正空气开关也打下了应该不会有电了，嫌麻烦就直接用尖嘴钳把电缆剪断，那一剪可使我终生难忘啊？直接听到一声爆炸声，眼前就像在漆黑的夜晚忽然打雷一样两眼看到一道白光。
