Star delta connected as above. The phases are in correct rotation (have a phase rotation relay in control circuit). Motor is running in reverse, but I can't for the life of me remember how to reverse the motor at the motor terminals. I can't just swap the MCCB feed so how should I alter the wiring at the terms to make the above work?
“It would be cleaner to swap any 2 phases at the point they enter the machine.”
I agree with Mike. It is safer to swap the 2 phases at the MCCB than do at the induction motor. I use to do this rectification for reversing a Star-delta motor. The motor rotated reverse as I need.
