Maintenance and repair of motor:

1. The operation environment should be kept clean and dry, the air inlet

    should not be obstructed by dust and fibers

2. Before each operation it should be strictly checked, whether the fasteners

    loose or fallen off, by occurrence of these phenomena the fasteners must

    be tightened at first

3. The bearings of ordinary three-phase asynchronous motor should be

    maintenanced after 2000 hours operation time, it's mainly clearing the

    bearings with kerosene or diesel oil, increasing grease according to the

    bearing capacity, make sure that the grease must be clean and free of

    impurities. The grease should be as much as 50% ~ 60% of the bearing

    inner ring. For a 2-pol motor it should be 1/3, too much grease will

    cause extra heating of the bearing, oil owing out of the wire wrap and

    damaging the insulation package

4. When the bearing life closing its limit, vibration and noise of the motor

    operation will significantly increase, the bearing should be replaced
