What are the main contents of daily maintenance and care of Mining Electric Motor?

1. Appearance inspection
Check whether the motor housing is damaged, deformed, corroded, etc.
Check the tightness of the end cover, junction box, fan cover and other parts.
2. Cleaning work
Remove dust, oil and debris from the surface of the motor.
Ensure that the air duct and heat sink are not blocked to facilitate heat dissipation.
3. Wiring inspection
Tighten the terminal to ensure that the connection is firm, without looseness and overheating.
Check whether the cable sheath is damaged or aging.
4. Bearing maintenance
Listen to the sound of the bearing operation for abnormal noise.
Regularly add or replace the appropriate amount of grease.
5. Insulation detection
Use a megohmmeter to measure the insulation resistance of the motor winding to ensure good insulation performance.
6. Brush and slip ring inspection (for brushed motors)
Check the degree of wear of the brushes and replace the severely worn brushes in time.
Clean the surface of the slip ring to ensure good contact.
7. Fan inspection
Confirm that the fan blades are not damaged or deformed, and operate normally to ensure ventilation and heat dissipation effects.
8. Check the tightening bolts
Check the tightening of the motor mounting bolts and anchor bolts.
9. Electrical parameter monitoring
Regularly measure the motor's current, voltage, power and other parameters, compare with the rated values, and determine whether the motor is running normally.
10. Magnetic field system inspection (for synchronous motors)
Check the status of components such as magnetic poles and excitation windings.
