In daily life, electric motors and reducers play a huge role in converting electrical energy into the mechanical energy needed in daily life. Today’s article shares with you some common problems and solutions to the following electric motors.
The engine hums but does not run

Engine overheating can be caused by a chronic lack of maintenance on the ventilation system or a poor supply of cooling air. To resolve this problem, clean the impeller that has accumulated dirt and lubricate the shaft and bearings. If the cooling fan system is still functioning properly, the problem may be caused by a motor failure or motor overload. At this time, please recheck the load or ask a professional to repair or replace the motor.

Electric motors produce strong noise and vibration when running
Excessive noise is a sign of motor problems. Motor noise is often related to motor vibration, which can lead to coil and bearing damage. The cause of the noise is usually a faulty shaft connection or an imbalance in the electrical or mechanical system. To resolve this issue, check for damaged bearings, loose joints, and presence of shaft connections.
Regular motor maintenance will help minimize the above problems. Some basic motor maintenance steps include cleaning dirt, lubricating bearings, and insulating windings. Do these things when necessary.
Electric motors produce strong noise and vibration
In order to minimize damage to the motor during operation, the design and production of the control cabinet is very important. The motor control cabinet needs to have the following protection functions:
- Prevent reverse phase and protect against lack of phase
- Undervoltage and overvoltage protection
- Overcurrent protection (overload)
- Short circuit protection
I hope the article shared today on how to solve common motor problems will be helpful to you when needed.
