Common Issues with Doubling Machine Motors
Release date:
2024-10-12
1. Power Supply Issues
-
Voltage anomaly : When the power supply voltage is too low, the motor struggles to start, and the inrush current increases significantly. Conversely, if the voltage is too high, it causes the motor windings to heat up excessively—both scenarios can ultimately prevent the motor from starting altogether.
-
Line failure : Aging power lines, damaged insulation layers, and poor contact can lead to abnormal current flow, preventing the motor from starting properly.
-
Three-phase voltage imbalance : It can cause the motor to vibrate during operation, reduce efficiency, and lead to abnormal current fluctuations, ultimately resulting in failure to start.
II. Motor Malfunction
-
Winding issue : Short circuits or open circuits in the motor windings can lead to abnormally high current while resulting in insufficient torque, or even cause the motor to run on a single phase, drastically reducing the starting torque and making it difficult to start.
-
Rotor failure : Breakage of the rotor bars or rotor eccentricity in a squirrel-cage induction motor can lead to a reduction in torque, slower starting speeds, and may even cause unusual noises during startup.
-
Bearing damage : Bearing wear or inadequate lubrication can lead to increased mechanical resistance, making it difficult for the motor to start.
3. Mechanical Load Issues
-
Overload : When the load on motor-driven mechanical equipment exceeds the motor's rated capacity, the motor may fail to start properly or run at an abnormally low speed.
-
Mechanical Transmission System Failure : Issues such as overly tight or slipping belts, improper coupling alignment, or mechanical equipment experiencing jams or blockages can all increase starting resistance, making it difficult for the motor to start.
4. Control System Issues
-
Contactor failure : Poor contact at the contactor's contacts, coil damage, and other issues can cause the motor to fail to start properly or experience abnormalities during startup.
-
Thermal relay malfunction : If the thermal relay's setting value is improperly adjusted, or if the thermal relay itself malfunctions, it may trigger unintended actions, causing the motor to fail to start.
-
Improper inverter parameter settings : If the motor is driven by a variable frequency drive, improper parameter settings—such as an excessively low starting frequency or an overly long acceleration time—can result in slow startup speeds.
5. Environmental Factors
-
Ambient temperature is too high. Poor motor cooling can cause the internal temperature to rise excessively, triggering the overheating protection mechanism and preventing the motor from starting.
-
The environmental humidity is too high. :The motor has become damp, leading to a decline in insulation performance and increasing the risk of faults like electrical leakage, ultimately resulting in failure to start.
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.

How is the insulation performance of the elevator door operator motor ensured?
Summary: Regularly perform insulation resistance tests on elevator door operator motors to ensure their insulation performance meets standard requirements.

Summary: Confirm whether the power voltage is normal and check for any voltage drops or abnormal power frequency.
