Do NOT get a static.
You can make a suitable rotary from a large[say 7hp in your case] 3 phase motor and a small single phase motor momentary start switch to spin the small motor and ge tth ebig one turning, then power to the big one, voila , 3 phase. You will not have as much starting stopping torque, so you may have to adjust some timing if your machine is really fast. You may also have to swap the legs around because the control won't want to run on the 'fake' leg.
I ran 2 cnc mills on a pair of homemade converters, so it can be done. |
