          22 reasons for motor heating

          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
