I'm getting ready to build a RCP to power up my new (to me) CNC lathe. All this is going to power up is the axis drives and spindle, the three small 3 phase motors for the coolant pumps and the hydraulics will be powered by VFDs from a separate feed, as will the computer and controls.
I have a 15HP compressor motor to use as the idler. 2 pole, 3450 RPM, 240 volt. I tried to remove the motor from the compressor head, but it turns out that the armature shaft and the screw are one piece. So I pulled out the mating screw, greased the bearings and put the housing back together.
Here is the schematic of the RPC. Comments are solicited and welcome. Starting is with the 3/4 HP, 3450 RPM, single phase pony motor to minimize the start load on my electrical system.
