Here is a picture of the Lathe. The main motor is two wire with a capacitor start, The label shows it is a Dayton 1725rpm 12.6A motor P/N 4K413A, I'm not sure if I got the part number, it was hard to read. I searched for information for that part number, but didn't find any. I did find a similar part number 4K141 listed as a capacitor start power tool motor, this one had different specs, but I think it's the same kind of motor. The other two motors have six wires, he said he thought they were vacuum cleaner motors. I can see two of the wires go to the brushes, the other four, I don't know. I have been reading about motors on-line for a few days, so I can guess the other four wires go to the stators. There is no starting cap, so one set of wires may be for an induction winding, set 90 degrees from the main winding to get the motor turning. Or the motor may be shaded pole, another way to get it turning. At any rate, it appears I have to connect the A/C line hot to one end of one winding, and A/C ground to one end of the other winding. The other end of both windings connect to the brushes. The direction is switched by reversing brush connection. I don't know what polarity to connect the stators, I'll just guess and see if it works. Now I'm ready to order some components. After I get a circuit together, I have a vacuum cleaner motor I can use to test and scope it out.When it works, I'll put it on the lathe and wire up those motors.
