I have an old 3 phase mill which has what appears to be a starter of some sort and other than that is simply switches and fuses. Is there any reason I can't feed the mill with a VFD into the starter as opposed to wiring the motor directly?
The reason I ask is the mill is a combo vertical/horizontal mill (Rambaudi VSR-2) with separate motors on the horizontal and the vertical. Instead of wiring a separate VFD to each motor I'd like to just power the mill at 100% and use the original circuitry/gears/belts for speed control.
Is there a good reason this wouldn't work?
thanks
