So is it possible to produce something that delivers current to an external load rather than heat the armature? Well we need to keep the low resistance present so that the L/R time constant is long, else we need impossible speeds. And IMO we can't have multiple turns so we need the single turn approach. I have come up with this wavy-line armature made from thick copper buss material that is connected via slip-rings to the external load. The output is AC. The first jpeg here shows the wavy-line directly above the magnets where the flux cutting voltage induction is a maximum, and at low speeds the current is in phase with that voltage so the torque loading is also maximum. The second jpeg shows the situation at high speed where the current is shifted by almost 90 degrees, and now the maximum current occurs with the wavy-line in between the magnets where torque is almost zero. So could this be an OU generator? I leave it to you construction guys to find out. If it works it will be a low voltage high current generator, with all the attendant problems of losses especially at the slip-rings. But as in homopolar generators there are ways of overcoming those.
