I've got a late 80's jet metal lathe that was wired 110v but has the option to be wired 220v. I'd like to switch it to 220v so I draw less amps in my shop.
I dont have a manual for the machine bit there are diagrams on the switch housing and the motor. I can't make any sense out of the one on the motor but the one on the switch seemed simple enough except for one thing.
For 110v it uses 5 wires. For 220v it only uses 4. I followed the diagram on the switch, plugged it in, no pops, sizzles or smoke so hey were good. Threw the switch in forward, nothing. Go to reverse and it makes a pretty good humm but doesn't turn. Almost acts like a bad capacitor but it ran fine before the rewire.
Apparently this motor has three sets of windings in it. One forward, one reverse and a starter winding.
I'll post some pics of how it was wired 110v and a sketchy drawing of how I have it now as well as the diagrams on the machine.
