    Will be a good watch to see just how long the bearings in the bar last. Not long at that kind of treatment.

    Here is the real deal, he didn't want his belts giggling so bad that they pop off so he made a secondary giggling bar

    Thanks Dave, I will have to make another rotor. It's an opportunity to make it better and thicker with more magnets, as I had already bought them few months ago.

    Liber63. I have the diameter of a magnet between each of the magnets on the rotor. I’m not sure that is necessary, but it is what I have always done.

    7th graders pulse motor, 4-5 watts input to turn rotor 4000 rpm for large 8" disk and many heavy magnets. Now add regenx coils

    I have not recorded any tests. I 've done thousand of them. Most of the time is preparing and testing different coils. What do you mean 'without jumping all over'? Rotor turns very smoothly and had it up to 2500 rpm, though most of my experiments don't need that many rpm. I am very happy around 1800-2000, or less. My problem of not having enough power on the coils, as a friend of mine suggested, is something I didn't know when making the rotor. He said I should have enough space between each magnet. He said it should be at least the diameter of a magnet or more.

    I want to ask Dave, what is the distance between his magnets? Is it enough for a virual magnet in between, or more?
    I am about to make another rotor with more space between the magnets.
    Hi Dave
    I understand you said you have no idea, why do i get half the power with double the magnets. In case you missed the above post, can you tell what is the distance between your magnets? Is it at least one magnet diameter? 'Cause i am not going to make another rotor if this is not a probable problem. At my rotor the distance between them is about 2/10ths less. Magnets' diameter is 22mm and the distance in between is 18mm.

    What a gift Doug has to engineer mechanical devices. And patient. See video on cogging which is a key element to this work. He is showing a lot of magnets interacting with cores of a double rotor system and spins up with 1 finger. "Strange but it almost wants to run itself."

    This guy is a mechanical genius. If I had the money to hire people he would be up to bat. He just needs a mill and lathe. Listen to the end of the video where he talks hows easy the rotor spins and doesn't "latch up" or cog.

    Doug Konzen overseas now, Hi Doug. The cogging is low.

    I AM SURE DAVE WILL SEE THIS AND HELP YOU AS HE HAS BEEN THERE FOR EVERYONE THE PAST 10 YEARS OR BETTER.

    Your virtual magnet space seems fine to me. As far as your friends statement goes I would like to see his build first. People talk but we need to see their build, ya know?

    We have all been told by Dave a million times. Slow rotor speeds give low coil output.

    Wide gaps give low coil output.

    Weak magnets give low coil output.

    Combine slow speeds with large magnet gaps and weak magnets and you will output little.

    As another example Thane Heinz runs 3600 rpms, 60 thousandths gaps from coil to core and strong magnets. Some of his rotors the magnets are 1/4" apart and other rotors 1" apart. These rotors all work fine and they are metal rotors not plastic.

    You have a nice machine there inspired by Dave Bowling and I wish you well on your many tests.

    Please post any tests being done which includes showing the rotor turning without jumping all over. Looks nice. How does it run?
