    Yes, OrionLightShip, satisfied smiles the world over attests to your observation.

    Concerning the Soft Iron powder, I have no direct experience with it, but I have in the past used paramagnetic "dirt." I added a thin glue and filled cores of coils for Bedini energizers. It gave me something like an air core's quick action as it did not hold the magnetism after the magnet had passed. I ran my small 6 coil machine (I added 3 more coils to one of Rick Friedrich's 3PM machines with its very small coils) at over 10,000rpm. I think that if you mix the Soft Iron with a resin that it will reduce the air that welding rods have in the core. The air creates heat because it gets energized and hits against the rods as it bounces around. I think this is one of the reasons that ferrite is cooler because it has no air inside.

    Alexelectric, thanks...I'll keep playing with it and keep ya'll informed. One problem with collecting data is that I am running it off of solar which is inconsistent AND it stops every night (don't know why...its a mystery ).

    Take care,

    Bob

    It's soft magnetic iron Mikey. Its' small particle size minimizes eddy current loss.

    I am not a motor builder, at least not on Dave's scale. I have a solid state energy transfer project that I bought this for testing the difference between air core and iron core and to have control of the inductance without having to position a ferrite rod.

    I will put it at 3mm, but first I will incorporate the neutralization of the magnetic drag, because as I have already said the attraction is tremendous, I remember Dave when he informed us how that drag burns the motors or increased consumption.
    Yes gap MUST be 3mm or less to get a reasonable EFFECT. ALL MOTORS used today
    use a much smaller gap than 1mm. You will not get what you are looking for.

    Hello again,

    Here's another video:

    https://www.youtube.com/watch?v=_GnX...ature=youtu.be

    This is the pendulum not swinging, but bouncing straight out from the magnet on the points. I didn't intend this, so it's not to my credit or fault...it's the pendulum revealing its secrets. This allows for a modification where there is no pivot on the arm. The flexibility of the arm and A-frame allows for the movement. I measured the frequency across the coil and it rapidly varies constantly between 48-68Hz.

    OrionLightShip, good to hear from you. (I just got a notification that somebody with a Russian name has subscribed to me, so things are picking). I will be doing that and other measurements and will post them here. I certainly do not have this perfected. I am constantly trying different things. I just added a diode that I think will keep more of the collapse of the coil going to the battery...we'll see.

    Take care guys,

    Bob

    regards BobFrench
    interesting your proposal, you continue to improve it, that good.
    I have a bedini motor when I connect it began to oscillate between two coils and magnets as a pendulum, I remembered your projects.
    Greetings and here pending your progress

    5-6mm is to big. Try 3mm or 2mm for best response. Not so easy for a cheap rotor.
    When I use 1/4" gaps nothing happens. I had to tighten the space up to 3mm or less.
    Now mine works.

    Air gap
    # of magnets on the rotor
    RPM
    core material
    # of winds in the coil
    wire diameter
    # of strands
    connections between parallel strands

    All these effect your input and output, because with THIS machine the output DOES affect the results you get with your input.

    Do you know what your air gap is?


    Of course, it all depends on the elements that are in operation.
    Everything is in accordance with its recommendations, it is a simple replica of the project, I only need 2800 rpm.
    I only use a coil of 256 feet and 12 cables, cable 23, connected in series of 4 and the resulting 3 in parallel
    The dimensions of the coil are of the reel you suggested.
    The core is welder, which is used in bedini
    The core is 5 mm from the rotor, the attraction is tremendous
    The rotor has 6 N52 2 "x 3/4 neodymium magnets
    If I build the 12 magnet rotor only 1400 rpm would be needed, if I ran it at 2800 rpm it would be more fem and amperage. For now, this simple project is enough for me to have the satisfactory results
    I have not incorporated magnetic suppression, I will add it

    I have to buy the engine you are using and your speed controller can remind me of the data.

    With all this, I am already advanced to demonstrate a viable replica of his Dave project, I have no doubts about his contributions and data, which he has entrusted to us, supports it in two patents, and viable electromagnetic principles.
    Every project requires work and effort.
    honor to who deserves it thanks Dave for sharing and supporting

    yt has been changed throughout the forum to video, which is the correct embed code for vbulletin now but vbulletin hasn't found a way to get the vids to automatically embed, they only changed the code.

    Would you just editing the post and saving (without changing anything in the post) so we can see if that forces the embed? Just click edit and then save.
    hello Aaron I just saw this post and I will try it if I can find which one. Thanks for your hard work.

    PS I am back and just pasted the yt links straight in and they work.

    Quickly, I just wanted to apologize to my new subscriber for referring to him as "Russian." I wasn't paying attention...the letters in his name are obviously Greek...duh. Sorry. Oh, and I just got another subscriber today...the place is fillin' up.

    Also, I thought that I should have mentioned in the last post that I put a diode directly off the input positive so that the positive of the collapsing coil would not go to the input. If the input was a battery I might not bother.
