Ok bois so my tractor lathe which i have been working on has el problemo. so i hooked it up with a new Belt because the old one was roached. and connected her up to 110V (yes i know 220 is optimal etc.) i did it just to see if the motor is brokey. it runs but its like its turning on and off, it spins up then stops then spins up. kinda like a dude at a drag race (revvvvvvvv pause revvvvvv). its rather odd and i think the motor is bad because on the motor it says PH-1 which is single phase and 115-220. so theoretically it should work just fine. So if the motor is in fact broken what are my options? ive read forms of people taking south bend 9" lathes and hooking up VFD's. which im not against using a VFD, but i would like to keep it as close to original if i can Thanks.

You need to connect the motor right for the voltage. However those symptoms don't sound like the motor but instead something else in the drive is dragging somehow and the motor can just barely power past. I'm guessing though, you need to get the motor wired right for the voltage first which means finding and reading the nameplate.
