Long time lurker here,
I'm in the final building stages of my dream shop and pulled the trigger on some equipment. I grabbed a 2HP First knee-mill a few weeks back and picked up a 17 x 54 7.5HP Cincinnati lathe on the weekend. I was going to have the motor rewound on the mill and go the VFD route, but since both machines are 575V I figure its easier to just stick with a RPC and transformer and run both machines plug and play.
I'm finding very conflicting information regarding the sizing of the RPC and transformer and am hoping for some real world insight from members who have been down a similar road.
I'm hoping to use a 10hp 240V 3ph motor as my idler and a 15kVa 240V-575V 3ph transformer to step the voltage up. The lathe is clutched and I don't plan on pushing it anywhere near full load. Does this seem ok or should the RPC really be 15hp+?
Thanks in advance,
-Luke
