观察电动机运行过程中有无异常，其主要表现为以下几种情况

1.定子绕组短路时，可能会看到电动机冒烟。

2.电动机严重过载或缺相运行时，转速会变慢且有较沉重的"嗡嗡"声。

3.电动机正常运行，但突然停止时，会看到接线松脱处冒火花；保险丝熔断或某部件被卡住等现象。

4.若电动机剧烈振动，则可能是传动装置被卡住或电动机固定不良、底脚螺栓松动等。

5.若电动机内接触点和连接处有变色、烧痕和烟迹等，则说明可能有局部过热、导体连接处接触不良或绕组烧毁等。

Observe whether there is any abnormality in the operation of the motor, which is mainly manifested in the following situations

1. When the stator winding is short circuited, the motor may be seen smoking.

2. When the motor is seriously overloaded or runs without phase, the speed will be slow and there will be a heavy "buzz" sound.

3. The motor runs normally, but when it stops suddenly, sparks will be seen where the wiring is loose; A blown fuse or a part is stuck.

4. If the motor vibrates violently, it may be that the transmission device is stuck or the motor is badly fixed, and the foot bolts are loose.

5. If there are discoloration, burn marks and smoke trails at the contact points and connections in the motor, it indicates that there may be local overheating, poor contact at the conductor connection or winding burnout.
