Professional motor maintenance and repair center motor maintenance process: cleaning the rotor - replace the carbon brush or other parts - vacuum class F pressure dipping paint - drying - school balance.
1. The use environment should be kept dry frequently, the surface of the motor should be kept clean, and the air inlet should not be obstructed by dust or fibers.
2. When the thermal protection of the motor continuously occurs, it should be ascertained that the fault is from the motor or the overload or the setting value of the protection device is too low, and the fault can be put into operation.
3. It should ensure good lubrication of the motor during operation. The general motor runs for about 5,000 hours, that is, the grease should be replenished or replaced. When the bearing is overheated or deteriorated during operation, the hydraulic pressure is changed in time. When replacing the grease, the old lubricating oil should be removed, and the oil groove of the bearing and the bearing cap should be cleaned by gasoline, and then the ZL-3 lithium base grease fills the cavity between the inner and outer rings of the bearing by 1/2 (for 2 poles). And 2/3 (for 4, 6, 8 poles).
4. When the end of the bearing life, the vibration and noise of the motor will increase significantly. When the radial clearance of the bearing reaches the following values, the bearing should be replaced.
5. When removing the motor, the rotor can be taken out from the extended end or the non-extended end. If it is not necessary to remove the fan, it is convenient to remove the rotor from the non-shaft extension. When the rotor is pulled out of the stator, damage to the stator winding or insulation should be prevented.
6. When replacing the winding, you must write down the form, size and number of turns of the original winding, wire gauge, etc. When the data is lost, you should obtain it from the manufacturer and change the original design winding at will, often making one or several performances of the motor. Deteriorated, even unable to use.
