Interesting. Did I mention that I signed a NDA on the Sprain motor?
We had a lively discussion!

For "cogging" EM motors, it seems to me to make sense to increase the
decelerating "cogging" angle to as much as possible, then put multiple
motors sharing their armatures in tandem but out of phase. For example,
if the cogging angle were 36 degrees, then 10 motors should cover the
full 360 degree circle. If the cogging angle could be made 120 degrees,
for example, then 3 motors in tandem should make for a perpetual motion
machine, assuming such is possible.
