Do you know the diameter of this unit, and the thickness? I do
think the idea is the best I've heard, but it might take a custom
built unit to do this. I would bet we could get someone to build
one, since everyone who's purchased one of Tracy's drives could
use it, and would probably want to. Cheers,
Rusty (the network guy today)
We should not overlook the disadvantage of PM alternators. At
higher operating speed, the not used output will have to be
dissipated. This is the main reason why automotive alternators are
regulated by the exitation system.
FWIW.

Rusty, I was looking late last night, but 1" thick comes to mind. Extrapolating from the pictures, I would guess about 6" in diameter? On the gearbox I have, it should be a comfortable fit, even with a few bolts sticking out. With a little luck, the stator could easily be situated to fit over any bolts. I'm pretty sure the effects of any induced eddy currents will be insignificant. (There I go guess again.) But a couple of solid rivets will be plenty enough to hold the rotor, and the center splines could be turned of in a lathe with a 1" bit quickly enough. And now that we have Bill saying that we won't have to rewind the coils, this just looks to easy.
Richard, that is what I thought. I was wrong, but you may not be 8*) The old regulators dumped the excess current to ground through a resistor. The newer ones (like 1970 is new), just block the excess electrons. In my mind, I picture them loading up like a spring until the motive force of the magnets pass, when they then unload, releasing their energy and doing absolutely nothing.
