I recently picked up a 13" South Bend Lathe, from the son of it's previous owner (who had passed away after several years of ill health). It's powered by a 1.5 hp 3 phase motor, and along with the lathe came a TP Electrical Rotary Phase Inverter. According to the son, this had been used to power the PO's equipment in several different shops and had been installed and moved by an electician friend.
The problem I've got is I have no idea how to wire this device, and there are no labels or markings on any of the wires attached to the unit (nor is there any attachement on the invertor to attach the lathe).
Is there some way to figure out what wires are for the 220v single phase in and which wires are for the 220v 3 phase out?
If I can't figure this out, my next thought is to go with a VFD to operate the lathe, but before I do that I want to make sure that the original motor is still functional.
