1. Excessively high room temperature; 2. Faulty fan or blocked air inlets/outlets, resulting in poor cooling; 3. Overload; 4. Overvoltage, undervoltage, or voltage imbalance; 5. Frequent start/stop or frequent forward/reverse operation; 6. Missing phase; 7. Bearings lacking oil.

1) Poor insulation, moisture. 2) Excess oil pressure, high current, overload; 3) Short circuit in the motor’s power cable. 4) Improper installation of the motor bearings. 5) Too much or too little grease inside the motor. 6) Lack of regular cleaning, resulting in poor ventilation and heat dissipation.
