I have a question about Motor- Drum Switch Wiring on this old 2 HP 220 volt 1 Phase motor.
It is an old Lima motor I would say at least a early 1950's motor possibly. This was pulled from my 15” Sheldon lathe when I bought it. I did power up the motor when I first got the lathe. Seem to run fine. Started with no problems. The motor was pulled and forgotten about until the other day. The guy I sold my 13” lathe to wants a 1 phase motor to replace the 3 phase motor and static converter. Won't get into details for the change out of the motor. I told him I had this 1 phase motor I would give him if he wanted it.
So I drug it up from the back porch, cleaned it off a little and proceeded to remove the makeshift cover to get to the wires to rewire it for his needs. This is the hornets nest I am into. Sorry for the blurred pictures.
The wires coming from the original forward/ reverse magnetic starter were just four and were marked 1, 2, 3, and 4. I only found one of the original wire markers out of all of the ones coming out of the motor.
Wires 1 and 2 have continuity, and wires 3 and 4 do not. So I assume 1 and 2 is the running winding and 3 and 4 have to do with the starting winding.
The two capacitors do not make any sense either. They are 450 mfd apiece. Both are electrolytic type and have separate wires going into the motor housing. Why would have that much mfd's for start up on a 2 HP motor! 5 HP maybe, 7-1/2 HP probably so. There is no oilfield run capacitors on the motor.
The motor nameplate has no meaning with what I see here to any of the wires that were currently used to run the motor.
I have not made any attempts to take the motor apart to see how it ticks.
My question is, How do you reverse this motor with only four wires?
It was apparently being done before I took it out of service. I left the wires intact with the motor, only cut them at the motor stating contactor, knowing someone would like to know how to hook it up.
My next problem is hooking this up to this drum switch I bought recently. A Chinese built switch that is supposedly to be good for 60 amps. There's no way to cram no. 6 wire in the case for 60 amp service! I'll be lucky to get 14 and 12 ga. wire in this case!
HELP!!!
