Six technical maintenance lift hoist motor

lift hoist motor is an important part, but also the most expensive parts in winch, if damaged, repair or replacement costs will be very expensive. Remind customers to take good care  hoist equipment es, tips are as follows:
1, the use of the environment should be kept dry, the motor surface should be kept clean, air inlet should not be dust, fibers and other obstacles.
2, when the motor thermal protection succession of action, should identify the fault or from a motor overload protection device or the setting value is too low, eliminating the fault can be put into operation.
3, should ensure that the motor is running good lubrication. General motors running 5000 hours or so, which should supplement or replace the grease is found bearing overheating or running metamorphic lubrication, hydraulic in time for grease. Replace grease should remove the old oil, and gasoline wash bearings and bearing cap tank, then ZL-3 lithium grease fills the cavity between the bearing inner and outer rings 1/2 (for 2-pole) and 2/3 (4,6,8 pole pair).
4, when the end of life of the bearing,wire rope winch vibration and noise motor operation will significantly increase, check the bearing radial clearance reached the following values, which should replace the bearings.
5, disassemble the motor, extending from the shaft end or side rotor can be removed. If you do not need to remove the fan, or removed from the non-drive end rotor is more convenient, out of the rotor from the stator, should prevent damage to the stator windings or insulation.
6, the replacement must write down the winding primary winding form, size and number of turns, wire, etc., when the loss of these data, should be obtained from the manufacturer, free to change the original design of the winding, often made of one or several performance motor deteriorated even not be used.
