Having a problem with my phase converter... Replaced it after a number of years of good use only to have one fail. Installed another, burned out the capacitor. New one now gives e a stall and growl when turning it on, anyone know anything about this. It is used on an older Bridgeport with a 3 phase one HP motor

Jim, unless you are running multiple machines off of it, change to a VFD.

THIS.
The older rotating phase converter scheme does NOT produce a clean 3-phase power source.
More like two phases 180 degrees apart and a third between them by 90 degrees.
The VFD makes a real, correct 3-phase at 120 degree each.

Just google it. I think several are on Amazon and Ebay. I have a Hitachi and a Westinghouse. Both work great.Any particular brand ? Running a 3hp lathe with a rotary right now. Single phase in..
Or where to buy?
