The brushless DC motor is a device composed of a motor and a driver. It is widely used in the machinery industry. Many people encounter the phenomenon of the motor process when using the device and don’t know how to deal with it. Let’s briefly introduce what to do. Deal with this situation.
1. The power supply voltage is too high, so that the core magnetic flux density is oversaturated and the temperature rise of the DC brushless motor is too high: If the power supply voltage exceeds the standard by a lot, communicate with the voltage department to solve it.
2. The power supply voltage is too low, and the temperature rise of the DC brushless motor is too high under the rated load: if it is caused by too much voltage drop on the power cord, we can replace the thicker power cord, if the voltage is too low, you can Contact the power supply department to increase the power supply voltage.
3. If there is a scorching wire, the iron core has been burned, and the iron loss will increase. We need to do an iron core inspection test to repair the iron core and eliminate the fault.
4. The stator and rotor cores are rubbed together: Check the cause of the failure. If the bearing clearance exceeds the limit, we must first replace the bearing to solve it.
5. Dust or foreign matter on the winding surface will directly affect the heat dissipation of the DC brushless motor. In order to avoid this situation, it is important to clean up in time.
The above points are about the treatment of the overheating phenomenon of the DC brushless motor. If you encounter this situation in the actual use process, you must solve it in time in order to ensure the normal operation of the equipment.
