How to deal with overheating of brushless dc motor?

A brushless DC motor is a device composed of a motor and a driver, widely used in the mechanical industry. Many people encounter the issue of motor overheating when using such equipment and may not know how to handle it. Below, we will briefly explain how to deal with this situation.

1.Excessive power supply voltage leading to saturation of the core magnetic flux, resulting in excessive temperature rise in the brushless DC motor: If the power supply voltage exceeds the standard by a large margin, it is necessary to communicate with the power supply department to resolve the issue.

2.Low power supply voltage causing excessive temperature rise in the brushless DC motor under rated load: If the voltage drop a lot in power supply line, you can replace it with a thicker power supply line. If the voltage is too low, you can contact the power supply department to increase the power supply voltage.

3. If there is a case of burnt wire, the core has been burnt, resulting in increased iron losses. In this situation, a core inspection test is required to troubleshoot and repair the core.

4.Friction between the stator and rotor cores: Inspect the cause of the fault. If the bearing clearance exceeds the limit, the bearings should be replaced to solve the issue.

5.Accumulation of dust on the surface of the winding will directly affect the heat dissipation of the brushless DC motor. It is important to clean it promptly to avoid such situations.

The points mentioned above are the methods for dealing with the overheating phenomenon in brushless DC motors. If you encounter such a situation during actual use, it is important to address it promptly to ensure the normal operation of the equipment.
