This is better than a two-for-one deal at Saul Goodman & Associates! I mean, come on! 220V to 20V? You're not just bending the laws of physics, you're breaking 'em, and then rewriting 'em! That's what I call real legal wizardry, my friend. If you ever need a patent for that magnificent invention, you better call Saul, baby! We're talkin' intellectual property! We're talkin' making you the next big thing since, I don't know, the invention of the wheel or something! Keep this high-voltage content coming, Gear Show! You're makin' history here!

    Rotors, my least favourite part of rewinding motors. Would suggest getting some high copper brushes though, as the plain carbon ones will burn out fast, and probably are already robbing you of a good chunk of power there, and thus RPM. Could also have wound it using a shunt field, original windings would have done well enough, though of course using heavier wire and series would make it a lot more powerful.
