I don't see how you could slow one shaft to make it turn like a coaxial. Has anyone else seen these things? I have no idea what they're really made for....but I had to quit looking at it because sparks and smoke came out of my ears! What the heck could a motor like that be used for?

Too bad you lost the link, now I am curious. If it is geared to make the shafts turn counter clockwise then we are out of luck. However if it has a split center winding and outer windings and is sort of stacked then maybe it could be managed.
