As the title says I've finally saved up a few thousand to get my old bridgeport running! Some of you may remember me but for those that don't here's an overview of what's going on.
About a couple years ago I bought a 72 Bridgeport series 2 for a hell of a deal. It's been sitting in my shop collecting dust while I saved up for the day I could afford a phase converter and transformer! Well that day has come! And I'm looking for advice on how to go about setting this up and what size RPC and transformers I'd be looking at. (A VFD will not work as the mill has 2 other DC drive motors and I'd like to retain all factory features)
The mill has a 4HP 440 3 phase motor. I have 220 single phase. The plan is to go from 220 single to 220 3phase with an RPC then step that up to 440 3 phase with a transformer. I believe I would need a 10hp roto phase and a 15kva transformer. Anyone with experience in this kinda stuff please let me know if I'm atleast on the right path!?
