If you can't find cheap three phase motors, you probably are not
looking in the right places. Try the scrap yards. I mean the yards
that supply steel scrap to steel mills. Not salvage yards.

As far as looking at a motor generator, have you considered using a
three phase induction generator?

Seriously, I did, and have experienced a lot of the same pricing
troubles and problems with the RPC idea that you have and so I still
want to keep looking at the motor-gen idea.


I have looked for surplus motors to build a phase converter but
frankly I have not found the oasis where they are available for cheap.
The shipping costs are usually the killer.
