The high temperature of the gate motor during the working process will make the operation of the motor unstable or even cause it to fail to work. There are many reasons why the temperature of the motor is too high. We can deal with it according to the corresponding method to avoid its impact on production as much as possible.

1. When the instantaneous voltage of the gate motor exceeds the rated voltage by more than 10%, or the instantaneous voltage of the motor is lower than the rated voltage by more than 5%, it will cause the motor to heat up and increase in temperature under the rated load. In this case, the voltage should be checked and adjusted. .

2. The unbalance of the three-phase power supply voltage of the gate motor will also cause the motor to heat up. This is because when the unbalance of the three-phase power supply voltage exceeds 5%, it will cause the unbalance of the three-phase current. The solution is to check and adjust the voltage. .

3. The contact problem of the power switch of the gate motor and the open circuit of the first-phase fuse will cause the operation of the lack of phase, which will cause the temperature of the motor to rise. The solution is to repair or replace the damaged parts.

4. There is an error in the winding wiring of the gate motor, which makes the motor running under the rated load overheat. The solution is to correct the wiring error of the winding wire.

5. The inter-turn or inter-phase short-circuit or grounding of the stator winding of the gate motor will cause the current of the motor to increase and the temperature to rise. The solution is to add insulation to the center or directly replace the winding.

6. The cage rotor of the gate motor is broken or the winding rotor coil joint is loose, which will cause the current of the maintenance network to increase and cause temperature rise. The countermeasure is to weld repair or replace the rotor.

7. When the bearing of the gate motor is seriously worn, it will generate a large amount of friction and generate heat. The solution is to check whether the bearing is loose and whether the stator and rotor are poorly matched.

8. The overload of the gate motor is also the cause of overheating. Reducing the load or replacing the high-power motor can solve the overheating problem.

9. Too frequent startup of the gate motor, too high ambient temperature, poor ventilation, etc. will also cause the motor temperature to be too high, reduce the number of starts, reduce the ambient temperature, ensure smooth air ducts, eliminate dust and oil, and keep the fan in good condition Running both can help with similar overheating issues.
