Hello all,

I'm not sure how to go about this. I have a milling machine that is 110V, 3/4 horsepower and simple forward and reverse. I have recently purchased a CNC software/hardware based controller for a VFD. I also have 220V single phase ready to go. I'm looking for an inexpensive VFD/motor combo that will work for my machine.

Thanks in advance.

Hello Cnced1

Welcome to the forum

You will need a single phase input three phase output VSD and a 220 volt three phase motor. You can not use a VSD on a single phase motor!!

These are available in most electrical equipment suppliers, but if you have difficulty getting on, I can probably organise one from here. It would be preferable to get one locally if you can.

Best regards

Thanks for the info Marke.
I'm in the USA and have found http://www.wegelectric.com/.
They offer a setup with a 2 HP odp or tefc 3 phase motor and a VFD with encoder feedback. Sounds like a plan to me. The more horsepower the better.
