I have a Delta (Invicta) RU-50 pin router, which I acquired last June. Previous owner used it on 3-phase power up until I bought it from him. Not having 3-phase in my basement, I consulted with American Rotary and bought one of their static phase converters. The converter is rated at 4-8 hp heavy duty for my 3 hp motor, because it's Brazilian made and supposedly hard to start. This was an engineer's recommendation.
Fast forward to today. I finally got the 240 wiring in my basement shop to run this and it won't turn over. Starts to turn for a half second, then stops - then repeats, about every second or so. On one occasion it tripped the overload on the switch.
Could I have a bum motor? Or should I try a different phase converter? Rotary? Any help appreciated as I needed this up and running today.
Cheers,
