Maintenance methods of motor

Professional motor maintenance and repair center motor maintenance process: cleaning fixed rotor - replace carbon brush or other parts - vacuum F level pressure dip paint - drying - Calibration dynamic balance.

1, the use of the environment should always be dry, the motor surface should be kept clean, the air inlet should not be dust, fiber and other obstacles.

2, when the motor thermal protection continuous action, should identify the fault from the motor or overload or protective device setting value is too low, after eliminating the fault, can be put into operation.

3, should ensure that the motor in the process of good lubrication. The general motor running about 5000 hours, that is, should be replaced or replaced grease, running found in bearings overheating or lubrication deterioration, the timely change of hydraulic grease. The replacement of grease, should remove the old oil, and the oil tank of gasoline to clean the bearing and bearing cover, and then the ZL-3 lithium grease filled cavity between the inner and outer rings of the bearing of the 1/2 (2 pole) and 2/3 (4, 6, 8).

4, when the bearing life is finished, the vibration and noise of the motor will be obviously increased. When the radial clearance of the bearing reaches the following values, the bearings should be replaced.

5, remove the motor, from the shaft extension or non extension of the rotor can be removed. If it is not necessary to remove the fan or to remove the rotor from the non shaft end, the stator winding or insulation should be prevented when the rotor is drawn out of the stator.

6, when the replacement of the winding must take note of the primary winding form, size and number of turns of wire, etc., when the loss of the data, should be obtained from the factory, change the original design of the motor winding, often one or several performance deterioration, even unable to use.
