Cause and treatment:

1, poor grounding or grounding resistance is too large - according to the provisions of good grounding, remove the bad grounding fault 2, the winding moisture - for drying treatment 3, insulation damage, lead touch shell - impregnated repair insulation, reconnect lead .

Symptom: The motor has a low speed with load

Cause and treatment:

1, the power supply voltage is too low - check the power supply voltage 2, the load is too large - check the load 3, broken rotor winding coil - replace the rotor
