      2021-06-19 08:40:58 207

      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
