There's a bunch of work they did in Australia with rewinding motors for lower voltage, and then running them at higher rpm. I don't know where the site was though, but somebody around here must know.
Hi e*clipse, the control board/driver/power board works fine. I've tested all the safety features and the basic functionality with a basic V/Hz scheme at around 320v or so and they work as expected. I'm getting my bigger motor's post turned down to 1" this next week so I can finally fit an encoder on it. I've been waiting on them to get back to me about a special order for a 1.125" encoder, but they never did. Once the encoder is on, I can start testing the FOC code. It would be really easy to change things for Permanent magnet synchronous. It would be just a couple lines of code to allow for field weakening.
