Motor maintenance process of motor maintenance center:

Clean the stator and rotor - replace the carbon brush or other parts - vacuum class F pressure dip paint - dry - calibrate the dynamic balance.

1. The use environment shall be kept dry frequently, the motor surface shall be kept clean, and the air inlet shall not be blocked by dust, fiber, etc.

2. When the thermal protection of the motor continuously acts, it should be found out whether the fault comes from the motor or overload or the setting value of the protection device is too low, so it can be eliminated

After failure, it can be put into operation.

3. The motor shall be well lubricated during operation. Generally, the motor runs for about 5000 hours, i.e. the lubricating grease shall be supplemented or replaced,

When the bearing is overheated or the lubrication is deteriorated during operation, the hydraulic pressure shall change the lubricating grease in time. When changing the grease, clean the old lubricating oil with gasoline

Clean the oil groove of bearing and bearing cover, and then fill 1 / 2 (to 2-pole) and 2 / 3 (to 4

6. 8 poles).

4. When the service life of the bearing is over, the vibration and noise of the motor will increase obviously. Check that the radial clearance of the bearing reaches the following values, namely

Bearings should be replaced.

5. When disassembling the motor, take out the rotor from the shaft extension end or the non extension end. If the fan is not removed, take out the rotor from the non shaft extension end

To facilitate extraction of the rotor from the stator, damage to the stator winding or insulation shall be prevented.

6. When replacing the winding, note down the form, size, turns, wire gauge, etc. of the original winding. When these data are lost, ask the manufacturer for them at will

When the original design winding is changed, one or several performances of the motor are often deteriorated and even cannot be used.
