Need Help! Old J head 1HP motor - CNCzone.com-The Largest Machinist Community on the net!

I have an old J head with a Fairbanks-Morse 1 HP motor. After having a friend help me rewire it from 440 to 220, I had it running for a day. Now it will not start quickly like it was(and should). It pulses and heats up quickly. I am running a static phase converter. Any advise or wiring help would be greatly appreciated!! I have recently rebuilt the head and now need to finish this project so I can sell the machine. I have bought another mill that is newer and I want to get it in the garage, but I need to get this one sold first. A properly running motor will help it move quicker!! THANKS!! Joe

Sound like the static phase converter might have gone bad. If the phase converter does not function the motor will not start properly and moan/groan and get hot. I would recheck all your connections for starters.

I will recheck. The phase converter is brand new.
