KNOWLEDGE BASE ---Why Does VFD Driven Motor Overheat During Running?
1. The ambient temperature is too high.
Cause: The variable frequency drive inside is composed of countless electronic devices, which will generate a lot of heat when it works, especially the IGBT will generate more heat when it works at high frequency. If the surrounding temperature is too high, the temperature of the internal components of VFD will also be high. The AC drive will report a high temperature signal and stop in order to protect its internal circuit of the AC drive.
Solution: Reduce the temperature of the place where the inverter is located and installing an air-conditioning or fan to cool the VFD is also a better solution.
2. Poor ventilation of the inverter.
Cause: If the air duct of the VFD or control cabinet is blocked, it will not only affect the internal heat dissipation of the inverter, but also cause the variable speed drive to overheat and give out an alarm.
Solution: Check and repair the inverter regularly, remove the garbage in the air duct and smooth the air duct.
3. The fan is blocked of VFD or damaged.
Cause: When the inverter fan is broken, a large amount of heat accumulates in frequency converter and cannot be dissipated timely.
Solution: Replace the fan for the frequency converter.
4. The application load of VFD is too high.
Cause: When the application load of VFD is too high, it will generate excessive current and produce a lot of heat. Sometimes the variable frequency drive will set an alarm because of overheat.
Solution: Reduce the load or increase the capacity of the VFD. In general, the inverter capacity should be considered to be 1.8 times of that of load power when we select an variable frequency drive.
