在电机的实际运行过程中，当出现过载情况时，电机转速会明显降低，电流同时不同程度地增大，由此将导致定子绕组因为电流过大发热，出现绝缘系统崩溃的故障。当电机转子因过载而出现被静止的极限状态时，电机会在很短时间内被烧毁。

　　但在电机的生产和制造环节，则要通过堵转试验测定电机的某些性能符合性。电机堵转是电机在转速为0时仍然输出扭矩的一种极限情况，电机堵转试验时会通过人为性的措施，保证电机处于静止状态。电机堵转时功率因数极低，堵转电流高可达额定电流的5到7倍，时间稍长就会烧坏电机。电机的型式试验测取不同电压下的堵转电流，而电机出厂试验时则按照一个适当的电压进行。

　　在电机运行过程中，因负载过大、拖动设备的机械性故障，电机本体出现扫膛等原因，都会导致电动机无法启动或停止转动的现象，终的后果是电机的绕组瞬间崩塌。

　　对于堵转电流的大小，我们可以认为三相交流电机处于短路状态，或者是负载电阻为0，所以主要由定子和转子电抗与外加电压相平衡，堵转电流就会很大。而对于同步电机，当电机被堵转时，反电势为0，电机的定子绕组则变成一个固定电压作用下的电感元件，所有的电压全部加载到电机的定子绕组上，因而电流会很大。
