Due to the long-term continuous use of the motor, coupled with improper operation by users, failures often occur, so professionals are needed to maintain the motor, which can save costs and improve the utilization rate of the motor.
To repair the motor:
1. Observe whether the motor is abnormal during operation.
2. When the motor is in normal operation, it should emit a uniform and light buzzing sound without murmur and special sound. If the noise is too loud, including electromagnetic noise, bearing noise, mechanical friction sound and so on, it may be a fault precursor or fault phenomenon.
3. The smell of the motor can also judge and prevent the fault. If a special smell of paint is found, the internal temperature of the motor is too high; if it is found that there is a heavy paste smell or scorching smell, it is possible that the insulation layer has been broken down or the winding has been burned out.
4. The temperature of some parts of the motor can also judge the cause of the fault. In order to ensure safety, the back of the hand should be used to touch the motor shell and the part around the bearing, and if the temperature is abnormal, it should be solved in time.
