Paul,
Sorry this has been so much trouble.
Can you get a simple, slowly rotating magnetic field (no feedback) to work? What happens in that case?
I'm going to test my free spinning rotor ( no stator ) with a piece of iron. It should simply align with that iron

Also, I got it to run "smoothly for a fraction of a revolution, and then it sloshes back and forth (but very smoothly). I'm becoming convinced that it's like 50% synchronous and 50% reluctance. I don't think you can just ignore the reluctance component, even for casual testing to get it to spin. What seems to be happening is, it rocks back and forth between where the reluctance component is near zero and where the synchronous component is near zero. So, what I"m going to do is get the reluctance correction code running on the Leaf motor (since that seems to be like 90% synchronous 10% reluctance), and then switch back to the mgr.
