Those are the lines along which I've been thinking ever since Erfinder alluded to it on another forum. I believe the point he was trying to make was that the bemf could be harnessed to assist the motor's turning, rather than a counter-rotational force to be overcome. This is something I'd love to investigate further. My sense is that this can be done in a motor without adding a second commutator at the other end of the rotor. It might simply depend on altering the direction of series coils on the armature in order that the cemf can be harvested. Just kind of thinking out loud. Perhaps you have a clearer idea. I suspect Erfinder may as well.
