Motor maintenance method of mobile lifting platform

1. When the motor of the mobile lifting platform replaces the winding, the original winding method, ratio and number of turns, wire gauge, etc. must be written down. When these data are lost, the original planned winding should be obtained from the manufacturer, and the original planned winding should be changed at will. This will often aggravate one or more functions of the motor, or even make it impossible to use. 2. The application environment of the mobile lifting platform should always be boring. The motor shape of the mobile lifting cage platform should be kept clean, and the air inlet should not be obstructed by dust, fibers, etc. 3. When the mobile lifting platform motor is disassembled, the rotor can be disassembled from the extended end or the non-extended end of the shaft. If it is not necessary to disassemble the fan, it is easier to disassemble the rotor from the non-axially extending end. When removing the rotor from the stator, avoid damage to the stator winding or insulation. 4. Ensure that the mobile lifting platform motor has good stability during operation. After the motor has been running for about 5000 hours, smooth grease must be added or replaced. When the bearing is overheated or running smoothly, the hydraulic pressure will change the smooth grease in time. When replacing the lubricating grease, take out the old lubricating oil, clean the bearing and oil groove of the bearing cap with gasoline, and then use ZL-3 lithium grease 1≤2 (for 2 poles) and 2≤3 (for 4, 6, 8 poles) ) Fill the cavity between the inner and outer rings of the bearing. 5. When the thermal protection of the mobile lifting cage platform motor comes one after another, it should be found that the fault is because the motor is still overloaded or the setting value of the protection device is too low, so that it can be put into operation after troubleshooting. 6. When the bearing life ends, the vibration and noise of the motor will increase significantly. When the bearing radial clearance reaches the following value, the bearing should be replaced.
