Three-phase induction motor is a type of motor commonly used in industrial production. It has the advantages of a simple structure, high reliability, and long service life, so it has been widely used in production. However, as the use time increases, various faults will occur in the three-phase induction motor, affecting its normal operation. In order to ensure the normal operation of the three-phase induction motor and extend its service life, regular maintenance and upkeep must be carried out.

Maintenance of three-phase induction motors

1. Regularly check the appearance and wiring of the motor to ensure that the appearance of the motor is not damaged and the wiring is firm and reliable.

2. Regularly check the bearings of the motor to ensure that the bearings are well lubricated and have no abnormal noise or overheating.

3. Regularly check the insulation performance of the motor and use a multimeter to measure the insulation resistance to ensure that the insulation resistance meets the standard requirements.

4. Regularly check the fan and radiator of the motor to ensure good heat dissipation of the motor and avoid overheating of the motor.

5. Regularly check the motor's rotor and stator to ensure that there is no damage or deformation of the motor's rotor and stator.

6. Regularly check the capacitor of the motor to ensure that the capacity and voltage of the capacitor meet the standard requirements.

7. Regularly check the power supply voltage and current of the motor to ensure that the power supply voltage and current are stable and avoid overloading the motor.

8. Regularly check the motor controller and protective device to ensure that the controller and protective device are working properly.

Maintenance of three-phase induction motor

1. Change the lubricating oil of the motor regularly to ensure that the bearings of the motor are well lubricated.

2. Clean the fan and radiator of the motor regularly to ensure good heat dissipation of the motor.

3. Clean the rotor and stator of the motor regularly to ensure that the rotor and stator of the motor are free of dust and dirt.

4. Replace the motor capacitor regularly to ensure that the capacity and voltage of the capacitor meet the standard requirements.

5. Replace the bearings of the motor regularly to ensure that the bearings are well-lubricated and free of abnormal noise and overheating.

6. Regularly replace the insulation material of the motor to ensure that the insulation performance of the motor meets the standard requirements.

7. Regularly replace the motor controller and protective device to ensure that the controller and protective device are working properly.

Precautions

1. When performing maintenance and upkeep, the power supply must be cut off first to avoid electric shock accidents.

2. When performing maintenance and upkeep, special tools must be used to avoid damaging the motor.

3. When performing maintenance and upkeep, operating procedures must be followed to avoid accidents caused by improper operation.

4. When performing maintenance and upkeep, attention must be paid to safety to avoid accidents.

To sum up, the maintenance and upkeep of three-phase induction motors are important measures to ensure their normal operation and extend their service life. When performing maintenance and upkeep, you must follow the operating procedures, pay attention to safety, and avoid accidents caused by improper operation. At the same time, attention should also be paid to regular replacement of the motor's lubricating oil, capacitors, bearings, and other components to ensure that the motor's performance meets standard requirements. Only in this way can the normal operation of the three-phase induction motor be guaranteed and reliable power guarantee be provided for production.
