Quotes are around 600 to 900 bucks for both a transfomer and a phase converter. Im not spending that.
Even if I want to keep 3 phase, I have to get a different 3 phase motor.
The DC motor was 80 bucks, I either use it here or somewhere else. The price of a motor drive should be less than the VFD. Basic internet search looks like about 100 to 150 for a drive board. With the DC you get all the power with the speed control.
So my options are,
1) use the DC motor which I have from a trade, but need motor controller, which I know squat about.....
2) buy a 220V face mount motor currently on sale, and its 2 hp so lots of power, and I still have all the pulleys for the different speeds, as was the origional setup,,, bolt it up and go, but no reverse switching,,
3) find another 3 phase that fits, must be the right voltage,,, and then get a VFD

Oops! I missed the goofy voltage. Go to
www.surpluscenter.com. They usually have several DC motor controllers for under $100, suitable for at least 1HP. These are very popular:

They also have a number of 3-phase motors for cheap.
