Here is the situation: I have an older (1950’s-era) Craftsman benchtop jointer, which i inherited from my grandfather. The motor, which I believe is after-market, does not have a cord anymore. It is literally just four wires; one coming out of each winding.
I’d like to wire this motor for 220V. There is no wiring schematic anywhere on/inside the motor. There is also no model number stamped on the faceplate, as you can see:
This has made it virtually impossible to obtain any information on the particulars of this motor. I’m afraid that if I hook the leads up wrong I could burn up the motor. I plan to tap a hole in the motor housing for a ground screw as well. Below are pictures of the stator, the starter/bearing and the rotor.
Starter/bearing – I flipped the end plate over when I took it off; in case the orientation of those magnet things makes any difference in the wiring:
Rotor – the left end of the rotor in the photo engages with the end plate of the above image:
I’m no electrician, although I am competent enough to have wired my own shop for 220V, so I feel like this is something I can do if I have the correct information. If there is anyone out there who can offer me any advice, I would be very appreciative!
