Ten common faults of the motor
1. Generator overheating
2. Generator neutral line has abnormal voltage to ground
3. Generator current is too large
4. Generator terminal voltage is too high
5. Low power
6. Stator winding insulation breakdown, short circuit
7. Short circuit between iron chips
8. The generator loses residual magnetism and cannot generate electricity when starting.
9. Excitation reactor temperature of automatic excitation device is too high
10. After the generator starts, the voltage does not rise.
