Common faults and maintenance methods of synchronous motors

Common faults of synchronous motors

Although synchronous motors can maintain high work efficiency in most cases, there may still be some faults, as described below:
1. Power reduction: Due to the inability of the rotor to rotate synchronously with the power supply, it may result in a decrease in the output power of the synchronous motor.

2. Vibration and noise: Synchronous motors may have issues with vibration and noise. This may be due to deformation of various components inside the electric motor, resulting in either unstable movement or noise emission.

3. System failure: Synchronous motors may experience issues with power supply voltage and phase balance, which can lead to system instability and malfunction.

4. Bearing failure: The bearings of synchronous motors may be damaged due to excessive use or long-term lack of maintenance, which may cause vibration and noise.

5. Mechanical damage: The speed control system may be damaged or malfunctioning, or the stator may have electrical insulation issues, resulting in abnormal motor operation.

6. Excessive temperature: Synchronous motors may be damaged due to excessive temperature. This may be caused by overload or short circuit.

In summary, common faults of synchronous motors may include power reduction, vibration and noise, system failures, bearing failures, mechanical damage, and high temperatures. In order to ensure the normal operation of the motor, regular maintenance and upkeep are required, and timely repair and replacement are necessary for damages and malfunctions. To deal with faults in synchronous motors, professional technicians are required to conduct regular inspections and maintenance of the motors.

Maintenance methods for synchronous motors
Synchronous motors may experience various malfunctions during operation and require maintenance and repair. Here are the maintenance methods for synchronous motors:

1. Check the power supply circuit: Check if the power supply circuit is normal, if there are any short circuits or poor contacts, etc., which need to be repaired.

2. Check bearings: Regularly inspect bearings for wear or damage, and replace or repair bearings if there are any issues.

3. Clean the interior of the motor: There may be dirt or dust inside the motor, and it needs to be reinstalled after cleaning. After installation, check if all components are complete.

4. Check magnetic flux: Check whether the magnetic flux is appropriate, which is the key to the normal operation of the motor.

5. Check the rotor: Check if the rotor is in the correct position and eliminate any abnormal situations.

6. Rotor flattening: When the bearing wears out, it may cause rotor deformation and needs to be flattened.

7. Replace magnet: If the magnet is found to be damaged or broken, it needs to be replaced.

In short, synchronous motor maintenance requires experience and skills. It is recommended to have a professional motor maintenance company or motor maintenance engineer handle the operation. Only through regular inspection, maintenance, and repair can synchronous motors ensure long service life and stable operation. At the same time, it is necessary to take corresponding maintenance and protective measures for the environment and management of the motor to extend its service life.
