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。
U0--任一绝缘导体和\\\\"地\\\\"(电缆的金属护层或周围介质)之间的电压有效值。U--多芯电缆或单芯电缆系统任何两相导体之间的电压有效值,当用于交流系统时,电缆的额定电压应至少等于所使用电缆系统的标称电压。
