Hello everyone,
I have eleven three phase machines in my shop that would love to help me get work done, but are sitting idle ( some of them for years) because I've never gotten around to building a rotary phase converter.
Well, now's the time.
I've started collecting parts to build an RPC. I have a 5hp, 1725 RPM 3 phase motor ( 14A @220) and a Furnas size 1 mag starter with fused disconnect. I'm a mechanic by trade, and while I have little problem repairing the used equipment that comprises my shop ( thirty-one vintage machines, the newest built in the late 1950's, the earliest sometime before 1903), I'm a little intimidated with drawing up a wiring diagram for an RPC; I just don't "get" electrical concepts the way I understand mechanical ones.
I understand the basics of how an RPC works, but the finer points ( start versus run capacitor layout, etc.) are confusing to me. I don't expect someone to do it for me, but I'll be the first to admit I need whatever help I can get.
Thank you,
