NEMA AC Induction Motor Connection Diagram

Details

Tips: Why The induction motor frame is electrified?
The reason for the motor frame with electricity may be that the motor shell is not connected with the ground or has been damaged. If the grounding equipment is damaged, the motor winding is affected with the damp and the insulation is aged. As a result, the current may leak out due to poor insulation. Or the outgoing line has been connected with the motor enclosure.
For this problem, first of all, check if the motor grounding equipment is perfect and reconnect it with the ground. If the motor get humid, it needs to be dried. The winding with seriously aged insulation should be exchanged.
