1. Conduct insulation resistance tests regularly

Regularly perform insulation resistance tests on elevator door machine motors to ensure their insulation performance meets standard requirements. According to relevant standards, the insulation resistance of elevator door machine motors under hot conditions should be no less than 2 MΩ. During testing, select an appropriate test voltage—typically, a 500V test voltage is sufficient for motors rated at 500V or lower.

2. Maintain a healthy operating environment

Keep the elevator machine room dry and clean to prevent moisture and dust from affecting the motor's insulation performance. Proper ventilation helps reduce motor temperature rise, thereby extending the motor's lifespan.

3. Inspect and Maintain the Motor

Inspect the motor's insulation material : Ensure that the motor uses insulation materials that meet standards, such as Class B insulation materials, which offer excellent heat resistance and mechanical strength.
Check the cooling system : Ensure the motor's thermal design is optimized and the cooling system functions properly to minimize temperature rise during operation.
Inspect the motor windings : Regularly check the continuity and insulation resistance of the motor windings to identify any turn-to-turn or ground faults in the windings.

4. Strengthen daily maintenance and inspections

Regular check-ups : Conduct insulation resistance tests on the motor according to the prescribed cycle, record the data, analyze the trends, and promptly identify any signs of declining insulation performance.
Timely repairs : Once an abnormal insulation resistance value is detected, the cause should be immediately investigated, and corrective measures taken. If necessary, the motor should be replaced.
Professional Training : Strengthen technical training for elevator maintenance personnel and enhance their awareness of the importance of insulation resistance testing.

What should I do if the 80 reducer motor makes loud noise during operation?

What should you do if the elevator door operator motor won’t start or is running at an abnormal speed?

What should I do if the 80 reducer motor makes loud noise during operation?

Summary: Check the bearings: Wear or damage to the bearings can cause noise during motor operation. Inspect the bearings for any signs of abnormal wear or looseness, and replace them if necessary.
