I had a 220v Jet 1236 lathe that I traded for a Rockwell 11" lathe. The Rockwell has a 230v 3 ph motor. Part of the trade was an OLD motor that supposed to be 3ph to generate the L3 phase to run this lathe. The guy I traded with had never wired it up so he was no help. Anyone have a wiring diagram or a good link for this?
I also have a box that was an original part of the lathe (from a local high school) that has a transformer, a Polyphase motor starter and a 3ph breaker in it.
The motor has NO markings on it - no name plate, no embossed company logo like GE or Westinghouse and no numbers on the 4 wires coming out of it. (It looks like it"s about 1930"s or 1940"s era.)
How do I test the wires to determine what"s L1, L2 & L3? What do I look for to determine which is the ground/neutral, the start leg and the L2 & L3 run legs? I"ll have to install machine grounds on the motor, box & lathe, too but that should be fairly simple.
I have a good multimeter, a good machining back ground and a good residential wiring back ground but I"m light in 3 phase and theory to figure this out on my own.
