Like woody said. A VFD is good for one motor. Controls would have to be rewired as well.

To use the VFD you will need to wire around the starter and any e-stops in place, but if you stick with 60hz any other secondary electrics should work fine. Any e-stops can be wired into the low voltage accessory circuit of the VFD so they will work as before. The economics all depends on whether the OP does indeed not acquire any more 3ph machines or possibly lucks into a used motor/starter that will work.

If you don t plan to go the RPC route just get in touch with Jack Forsberg, he is active on many of the forums under his own name, and buy a VFD to run it. He is the man for quality/price and in particular 1ph in 3ph out VFDs for higher horsepower machines.

Definitely this. ^^^
VFD technology is like magic sometimes.
I sold a three phase wall fan to a single phase customer, and we had to source one of these drives. It worked like a champ!

Do they make VFD’s for 10HP motors that don’t cost thousands of dollars? I looked into an RPC but it was $1,600. I could get a factory new motor intended for my specific machine for under $1,500.
