Funny - that's what I woke up thinking may work! I think it would work great for Paul's induction motor; after all they require slip, so an accurate position isn't necessary - right?
OTOH, accurate position is very helpful for PM motors; and that's the current issue.
Soooo, the idea is to take the encoder off the induction motor he has and make it work on the PM motor he just got. The reluctance encoder could be set up for the induction motor. I think it's a great set of experiments.
Paul- if you'd like to try this, I'll machine an adapter for the different motor shaft diameter.
