Here is the first picture showing the pieces.

Here is the first of 4 sets of coils

    So four stator coil sets and two magnet rotors sadwiched between them? Are the magnets in a non-metalic rotor? Is there cogging with this turbine? Nice post.

    Correct, the Coils are wound with very small wire I would guess something like 32 gauge? They are wound around laminated steel core about 2 inches long and 7/8th square.

    Yes the Magnets appear to be pressed into a HD wood pressboard.

    If I recall correctly you can feel very slight cogging... but don't quote me on that....

    This is a 200 Volt Model. Due to all the Coils the AC is Rectified in the turbine itself and sent down the tower as DC voltage.

    I Took it apart to see if I could rewire it to a lower voltage, but I don't feel comfortable at this point rewiring anything....

    Thanks for the answer. Just my opinion but the risk of rewiring for lower voltage may increase the heat in the stators. My suggestion would be to take these pictures to feildlines otherpower forum and hope some one like flux would answer. someone there might have already converted on of these for battery charging. I do find it interesting but garrentee my knowlage is not good enough that I could rewire it and know what I ended up with. If you just split the coils in half, you might be able to use it with a midnight classic but unless you live in vertual hurrican area year round it the out put might not be worth the 800 bucks for the cc.
    Please keep us posted.

    I do live in a "hurricane area" Wyoming 13 mph average wind.
