The best I can tell is that only the controller is working (well beta at least). So no power stage yet?

Well, certainly both Paul and I have built controllers complete with power stage and everything. Both of us have spun a motor with said controller as well. But, I don't have anything I can really release and say "this works. you can build it like this too."
So, quick summary of what has been done to date:
* Firmware which implements PID loop for throttle and V/Hz control of a three phase AC motor
* PCB of an IGBT halfbridge driver
* Prototype controller (control + power stage) put together - A bit of the PCB has been laid out by me but not yet released
* On my end several blown up IGBTs
I haven't worked on the project in a while because I've had other things to do. However, eventually I'll get back to it.
