The rotary phase convertor (RPC) I'm building is sized to run woodworking machinery that's about the same size as the idler. I've got a 7.5HP saw/shaper, 7.5 HP joiner/planer, 7.5 HP sander and 5.5 HP dust collector. I'd expect to always be running 1 machine + the DC, so running HP will be in the 12HP range. My idler motor is 15HP. I've sized breakers/contactors/overloads so I can run 2 machines + DC and just wouldn't start the machines at the same time.
Question - can I run a small load on this RPC? For example, I'm now looking at line boring equipment that has small (1.5-2 HP) motors in relation to the RPC. Is that a problem? Or - is this the reason to have multiple idlers that get pulled in as HP needs increase?
I don't really want to go back and start the scrounge process all over again to swap out the 15HP idler and all the controlling gear to go to a dual-7.5 HP idler setup.
