BAIXIANG MOTOR CO.,LTD.

The reason:

1. The power supply voltage is too low, and the temperature rise of the machine is too high under rated load.

2. The ventilation of the device is poor or the ambient humidity is too high.

3. The device is overloaded or in single-phase operation.

4. Frequent mechanical starting or excessive number of positive and negative rotation.

5. Stator and rotor rub.

Treatment method:

1. Measure the no-load and load voltage.

2. Check the motor fan and clean the ventilation channel, strengthen ventilation and reduce the ring temperature.

3. Check the current of each phase with a clamp ammeter and treat it accordingly.

4. Reduce the number of positive and negative rotation of the equipment, or replace it for frequent starting and positive and negative rotation.
