Sorry Supershot right now I have no way to put pics on line, but I'm working on it. I'll do my best to describe it. The rotor or armature is hollow and wound with wire thinner than a human hair. The magnets go inside the rotor, they are attached to the middle of the metal case. The shaft goes through the magnets, the armure goes between the metal case and the magnets. The brushes are like two split hairs. I think it's ailen technology
. If you can spare one take it apart you'll amazed as I was. NOTE don't squeeze the armature remember it's hollow and VERY fragil. I hope that helps it's really hard to describe.
