On a bench. I do have a golf cart with a DC motor inside, so a good choice for me would be a motor I could mate to the transmission. Like some sort of 3 phase AC golf cart motor, that's maybe 48 or 72vDC input that comes with an encoder. That would get the current up, and give the FOC more resolution.

I have a 3 phase 12v BMW alternator that Otmar let me borrow. It doesn't have an encoder. I also have a 208vac 3/4HP I think. It even has an encoder, but I don't know if I can push enough current through it to actually test the FOC code. Sure I can get it to spin with a V/Hz sort of thing. Can you drive with V/Hz as the software? With an encoder, it could be pretty smart.
