A follow-up video showing this repulsion-start induction-run motor now that it has been cleaned up and serviced. The motor was covered in a mix of oil and wood dust that had to be cleaned by a complete disassembly and washing in hand-hot water and dish soap. It took about a week for the stator windings to dry out and record good insulation test readings (now over 10 M Ohms). The motor has four wires that can be configured for 110 or 220 VAC, although I've only tried it on 230/240VAC. Under no mechanical load, the motor draws about 3.5 A during startup and 1.5 A running. The rotor direction is easily reversed by adjusting a small set screw - see the video for details. Some wires have been resleeved with heat shrink tubing to maintain their integrity. The stator windings have been given a light spray over with with electronic conformal coating.
