What are the hazards of grounding the motor winding?

When the motor winding is grounded, it will cause the winding to heat up, which will cause the winding to short-circuit and even make the motor unable to run; it will also make the motor casing electrified, which may easily cause personal electric shock accidents; when the grounding is serious, the motor will not be able to close the switch. Therefore, the insulation condition of the motor winding must be checked frequently, and once the winding is grounded, it must be repaired in time.
