OK I have a 50 HP Wye start Delta run Baldor motor
.
I have 200 amps Inductive ( as per POCO, but more like 160 constant ) going to shop ( 320 amps divided by 2).
I am wiring all the power directly to my RPC after going through a Square D QDL 22200 breaker. I am wondering if I just go with the 60 HP capacitor cabinet that has separate run and start caps and potential relay and all the good stuff for $650. Instead, should I go with a 3hp single phase pony motor? I Know I have to use run caps to balance everything.
I'd like to use a foot pedal belt tensioner arrangement like this guy.
Rotary Phase Converter to convert single phase 240v to 575v , 3 phase, 575v / 600v / 7.5 hp - YouTube
I especially plan on using that cam that activates the pony motor via the foot pedal when engaged and would like something that powers up the idler when the pedal is pulled back by return spring. Release the foot pedal when idler up to speed and then engage power to idler. I plan on using 1 way clutch on the Idler shaft. Either way, the RPC is going to be outdoors and I am thinking I can't get a TEFC single phase small HP motor so easily. Can I use the usual cheapie single phase 240 VAC compressor motor outdoors. Its gonna be under a cover, but not climate controlled etc. I wish I could get a car starter to run as the pony and use some kind of flexplate like arrangement and ignition switch to start the whole thing. But don't see how to get the necessary 1700 RPM to idler shaft using that.
So first question, should I go with start caps or Pony motor considering my amperage. Any suggestions for good pony motor arrangement if that is the better route?
