My 10 hp RPC just crapped out so am considering a VFD to replace it. I was using the RPC to power my 16" South Bend and my J head Bridgeport mill (never at the same time). The lathe has a 3 hp motor and the mill has a 1-1/2 hp motor. Am considering a 3 hp VFD to be used with both machines. Don't plan on using the VFD to regulate speed just to provide 3 phase power. Can the VFD be wired so that it will work with either machine or would I need a separate VFD for each machine? Also would prefer American made VFD so would appreciate recommendations.
