well, what is there to tell. . .
The bearings are the motor from an old 5.25 inch hard drive.
The magnets are from maxtor hard drives. Those little kidney--bean shaped magnets that have only one pole on each face. (takes 4 of them per drive instead of two like with others.
Those magnetsa re mounted on the teeth of a 5 inch circular saw blade. 20 teeth, 20 magnets. . .
The coils (20 of them) are centered on the magnets. The blade and the thing it is mounted to is the armature of the 20" box fan.
It is two sets of 10 coils in series, wired together parallel.
It'll put out about 40VDC in a stiff wind.
It is keeping two 6V golf car batteries charged at a remote cabin. (cabin has a incandescent over the sink and a flourescent over the table and that is all it does, but works great.
Keeps those batteries at 12.8V after the weekend drain to about 12.3. . .
Anything else?
