电机旋转方向是按照的方向进行的，如果是三相电机，输入的是顺时针旋转，我们就可以这样控制，如果是180度的话，那么电机的转向是180度，如果是正反转，就要把三根相线的位置信号改接为正转。
电机正反转，将其电源的相序为ABC，电机正转时，电源输入相序为ACB，那么电源输入相序为ACB。
当电机反转时，电源输入相序为ACB，那么电机的正转将迎来一个逆时针旋转，我们姑且图为正转，这个反转即是相等。
顺时针是正转，我们知道，电机能够转动的，相对于转动的方向相反，从电机开始任何一个方向旋转都是逆时针。
如果想形成一个定时，方向是逆时针，那么调换相序为ACB。
如果想形成一个定时，那么调换相序为ACB，则是反相序。
如果想形成一个定时，那么调换相序为ACB，那么调换相序为ACB。
因为电机正反转时，电源输入相序为ACB，那么调换相序就可以改变电机的旋转方向。
如果你的电机是逆时针，那么调换相序为ACB，则是从ACB到ACB的反相序。
如果是三相，那么调换相序为ACB，则不必要改变旋转方向。
