if you hunt the internet, you should be able to find an industrial grade inverter(110/220 input with 3 phase 220 output)that also has a variable frequency function for $200 or less(I just bought a 3hp Leeson for $150 delivered. then shop and you can find industrial grade motor to go with it for $200 or less. there are many places on line that sell last years model for less than 1/2 of current model. we are talking motors and motor controls, not computers. very little has changed in the way motors are made(other than some companies moving their factories off shore to save a buck) in the last 50 years. should be able to find someone help you do the wiring, wow, 7 wires. the book that comes with the inverter will show you exactly how to wire it and there will be a picture on the motor also.
