Product Details

In the daily maintenance of stage electric hoists, the maintenance of the motor is of crucial importance. The following are the specific maintenance details: Clean the Motor - **External Cleaning**: Regularly use a clean soft cloth or compressed air to remove dust, oil stains, and debris from the motor housing, preventing these contaminants from accumulating and affecting the motor's heat dissipation. Pay special attention to cleaning the ventilation openings of the motor to ensure smooth ventilation. - **Internal Cleaning**: Open the motor end cover at regular intervals (such as every six months or once a year), and use dry compressed air or a hair dryer (set to the cold - air mode) to blow away the dust and debris inside the motor. However, during the operation, be careful to avoid damaging the windings and insulation layer inside the motor. Check Motor Components - **Check the Wiring Terminals**: Examine whether the motor wiring terminals are loose, discolored, or show signs of ablation. If loose, tighten them in a timely manner. If discolored or ablated, find out the cause and replace the damaged terminals to ensure good electrical connections of the motor and avoid overheating or damage to the motor due to poor contact. - **Check the Bearings**: Judge the condition of the bearings by listening to the sound and feeling the vibration. During operation, if the motor emits abnormal noise or has excessive vibration, there may be a problem with the bearings. You can use a stethoscope or a similar tool to get close to the bearing area and listen carefully for abnormal sounds such as friction or impact. In addition, you can also turn the motor shaft by hand to check if it rotates flexibly and whether there is any jamming or abnormal resistance. If there are signs of bearing damage, replace them in a timely manner. - **Check the Insulation Resistance**: Regularly (such as monthly or quarterly) use an insulation resistance meter to measure the insulation resistance of the motor windings. Generally, the insulation resistance of the motor should not be lower than 0.5 megohm. If the insulation resistance value is too low, it indicates a decline in the motor's insulation performance, and there may be problems such as moisture ingress or insulation layer damage. At this time, the motor needs to be dried or the damaged insulation part needs to be found and repaired. Ensure Good Heat Dissipation - **Check the Cooling Fan**: Check whether the motor cooling fan is firmly installed and whether the blades are damaged or deformed. The fan should operate smoothly without abnormal vibration or noise. If there are problems with the fan, replace it in a timely manner to ensure that the fan can effectively dissipate heat for the motor. - **Keep the Heat Dissipation Passage Unobstructed**: Check whether there are obstacles around the motor to ensure that the motor heat sink and ventilation ducts are not blocked by debris. The motor should be installed in a well - ventilated location with sufficient surrounding space to facilitate air circulation and improve the heat dissipation effect. Other Maintenance Work - **Check the Motor Temperature**: During the operation of the motor, regularly measure the motor temperature with a thermometer or an infrared thermometer. Under normal circumstances, the operating temperature of the motor should not exceed its rated temperature. If the motor temperature is found to be too high, stop the machine immediately for inspection, find out the cause and eliminate the fault, such as whether it is overloaded, has poor heat dissipation, or there is a fault in the motor itself.

- **Lubricate the Motor Bearings**: According to the requirements of the motor instruction manual, regularly add appropriate lubricating grease to the bearings. Generally, it is necessary to replenish or replace the lubricating grease every 2000 - 3000 hours of operation or about every six months. When adding lubricating grease, pay attention to the right amount, as too much or too little may affect the performance of the bearings.
