the video shows the very low friction of the flywheel and alternator combination ,and the flywheel action
the alternator stator is made in sections of three coils each , creatively wired together.
it has 24 poles 18 coils when done ,9 on there so far.
i had a bunch of coils laying around so that is what i used.
the rotors and hub are from a motorcycle front brake and whatever kind of metal its made of it dosent rust , unlike the minigenII's rotors which are cast iron have rusted allready in spots around the magnets
i fliped one of the rotors around so that the gap between rotors is about 2.9" and with 1" wide by .875 dia. neo magnets that leaves a magnet gap of .9 inches
i used the hole pattern the rotors to drill the sprocket that is attached to the rotors .
the drive sprocket to the alternator is also a bicycle sprocket that i attached to the flywheel
