Thanks for the tip, the rotary phase converters don't have the
flexability i want and are to noisy for me. I was thinking about
using one of my old note book computers interfaced to some power
semiconductors and hopefully end up with a user programable vfd.


Do not underestimate the cost of this project, and you will end up
with something rather substandard. But it is fun.

For example, single phase input rated, 1 horsepower VFDs can be bought
on eBay for about $47 plus $12 shipping. It is hard to beat that.
