I remember (long ago, in college physics) learning about electric motors and generators, specifically about the "exciter" coils in generators which did a better job than permanent magnets, because of a sort of "turbo" or force-multiplier effect.
I notice, however, that while basically ALL generators use two sets of coils, NO electric motors do that. I would GUESS that it would be a simple way to make a stronger motor: Put your power into both sides of the attraction/repulsion rather than leaving one to a permanent magnet.
But no one does it that way.
What am I missing?
