If you want to build a rotary phase converter just do a google search
for phase converter and George Carlson he has an great page on this.
If you want the VFD way check out automationdirect.com or e-bay. be
warned some older VFD's choke on single phase inputs. I have a 3 hp
rotary running a 2hp mill. It runs good on low speed (2 speed motor)
but will not run it in high speed. my 5hp will run it in both speeds
with out any problem. Make sure you balance the voltage on your three
