China 12v Gear Motor maintenance process
China 12v Gear Motor maintenance process:
Clean the stator and rotor of the geared motor, replace the carbon brush or other parts, vacuum F-grade pressure dipping paint, drying, and school balance.
1: The 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 found 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 that the motor is well lubricated 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 changes grease 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 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 disassembling the motor, it is convenient to take out the rotor from the extended end or the non-extended end. If it is not necessary to remove the fan, it is convenient to take out the rotor from the non-shaft extension. When the rotor is pulled out from the stator, it should be prevented from damaging the stator winding or insulation.
6. When replacing the winding, you must record the form, size and number of turns of the original winding, wire gauge, etc. When the data is lost, it should be obtained from the Shenzhen Oding gear motor manufacturer, and the original design winding can be changed at will, often making the motor a certain item. Or a few performance degradations, or even unusable.
