Motor regular maintenance and maintenance methods

To ensure the proper functioning of high-voltage motors, in addition to following the operating procedures and ensuring regular monitoring and maintenance during operation, regular inspections and proper motor maintenance are also required. This can help eliminate problems promptly, prevent malfunctions, and ensure safe and reliable motor operation. The interval for regular maintenance can be determined based on the type of motor and the operating environment.

Regular maintenance for high-voltage motors includes the following:

1. Clean the motor. Promptly remove dust and sludge from the exterior of the motor base. If the operating environment is dusty, clean it once a day.

2. Inspect and clean the motor terminals. Check the terminal box for loose or burnt screws.

3. Check all mounting screws, including the anchor screws, end cap screws, and bearing cap screws. Tighten any loose nuts.

4. Inspect the transmission system, including the pulleys and couplings, for signs of wear and damage, and ensure they are securely installed. Ensure the belt and its couplings are intact.

5. The motor's starting device should also be cleaned of dust and dirt, and the contacts should be cleaned. Check all wiring connections for burn marks and ensure the grounding wire is in good condition.

6. Bearing Inspection and Maintenance. Bearings should be cleaned and lubricated with new grease or oil after a period of use. The timing of cleaning and oil changes depends on the motor's operating conditions, operating environment, cleanliness, and lubricant type. Generally, cleaning and oil changes should be performed every 3-6 months. Motors operating in high oil temperatures, poor environmental conditions, or high dust levels require more frequent cleaning and oil changes.

7. Insulation Inspection. The insulating capacity of insulating materials varies with dryness, so it is important to check the dryness of the motor windings. Humid operating environments and the presence of corrosive gases in the workspace can damage electrical insulation. A common cause is a winding grounding fault, where insulation damage allows live parts to come into contact with metal parts that should not be live, such as the housing. This fault not only affects the normal operation of the motor but can also endanger personal safety. Therefore, the insulation resistance of the motor should be checked regularly during use, and the motor housing should also be properly grounded.

8. In addition to the regular maintenance mentioned above, the motor should undergo an overhaul after one year of operation. The purpose of an overhaul is to thoroughly inspect and maintain the motor, replace missing or worn components, completely remove dust and dirt from inside and outside the motor, check the insulation, clean the bearings, and inspect them for wear. Any problems identified should be addressed promptly.
