        22 reasons for motor heating

        What are the reasons for Motor Heating?

        FSTpipe

        1. The room temperature is too high

        2. Poor heat dissipation

        3. overload

        4. Overvoltage, undervoltage or unbalanced voltage

        5. Frequent start and stop or frequent reversal

        6. Lack of phase

        7. The fan is broken or the air inlet and outlet are blocked

        8. Bearing lack of oil

        9. Mechanical jam

        10. The load moment of inertia is too large, the starting time is too long

        11. Short circuit between turns

        12. The internal wiring of the new motor is incorrect

        13. Wrong star-delta wiring

        14. Star-delta or self-dual step-down start-up load restart time is long or abnormal conversion due to fault

        15. Motor is damp

        16. Broken bar of squirrel cage asynchronous motor rotor

        17. The rotor winding of the wound asynchronous motor is broken or the resistance is unbalanced

        18. Rotor sweep

        19. Power harmonics are too large, such as large rectifier equipment, high frequency equipment, etc. nearby

        20. The magnetic flux of the motor core after repeated maintenance is reduced

        21. Some motors have poor winding technology

        22. The high temperature of the motor is generally unlikely to be a bearing problem, unless the bearing temperature is too high
