Alternator Porn

I took one of the alternators apart to see what it looked like inside. When I opened it up it looked like the magnets might have been rubbing up against the inside of the coils. You can see that the outer edge of the magnets are worn down and the inside of the wire coils are scratched, but this might just have been from the machining of the parts. The shaft seems to rotate a little more freely now, but we might want to file down the edges a bit.

On left: note the rectifier sitting inside the cover. On right: the magnet rotor sitting inside of the coil ring. You can see the three sets of coils that comprise the three-phase configuration.
