交流电机极数判别技巧

为了能够快速准确的判别出交流电机的极数，根据交流电机绕组接线图的接线规律，找到了一种判别的方法。该方法先找到电机绕组的其中任意一相，标注上电流运行方向，然后将相邻且电流方向不变的作为电机的一极，这样就能得到总极数。本文通过举几种较典型的例子说明此判别方法的可行性，为交流电机的设计和修理打下坚实的基础。

Judging the number of poles of AC motor

In order to judge the number of poles rapidly and accurately, according to the rule of wiring diagram of AC motor, seek a way which can judge it. firstly find out discretional a Phase of AC motor and label the direction of electric current, secondly contiguous and same label regard as a pole, so get the total of pole. This paper give representative examples to show this way which is feasible, and establish a foundation for designing and repairing.
