Hollow Shaft Electric Motor Troubleshooting:

1. After the motor is turned on, the motor cannot start, but there is a click?
  The power supply is not fully turned on to single-phase start; overload; wiring error or disconnection, short circuit
2. the motor is difficult to start, after the rated load, the speed is lower?
The power supply voltage is low; the corner connection is incorrectly connected to the star connection; the cage end of the rotor is unwelded, loose or broken
3. after the motor starts, the heat exceeds the temperature rise or smoke
The power supply voltage is too low, the ventilation is poor or the ambient humidity is too high; the overload; the start-up is frequent or the number of positive and negative reversals is too high.
4. low insulation resistance
Damp or dripping into the motor; dust and oil on the windings; insulation aging.
5. the motor casing is charged
The end of the winding touches the casing; there is no reliable grounding
6. the sound is not normal when the motor is running
Stator winding connection error; lack of lubricating oil
7.motor vibration
Uneven foundation, fan, rotor, pulley or coupling unbalanced; shaft bend or pulley eccentric

Hollow Shaft Electric Motor Daily Maintenance:

1. Do a good job of regular inspection and maintenance. In the annual overhaul, the motor is dismantled and maintained, the bearing is cleaned or replaced, the insulation is inspected, the cooling system is perfected, and the motor is in good condition;

2. The integrated management in the operation is strengthened. In the process of using the motor, the liability system is strictly implemented. The maintenance personnel will regularly check the inspections every time, observe and monitor the motor, and find out the problems in time to ensure the quality of maintenance.

3. When repairing the hollow shaft electric motor, it is necessary to ensure that various parameters meet the technical requirements of the motor, strictly control the quality of the replaced parts and the enameled wire, correctly operate the various processes, prevent human-induced residual accidents, and improve the quality of the motor after repair;

4. Ensure control The system is running fine. For each electrical component in the second line of the control motor, it is necessary to check and maintain it regularly to ensure that it is intact. The overcurrent short circuit protection device should be regularly checked to ensure reliable and sensitive operation so that the motor is always in good running state.
