    Hi bromikey, thanks for the tips.
    Wow, nice coil/core you have there, is that 29awg. wire, looks thicker.

    Don't think it will be a problem to get 1/16" gap, the rotor runs very true, meaning imperceptible wobble.
    Will add some super glue to each rotor magnet just in case and a barrier.
    Still seems a little hard to believe, that closing the gap by only a 1/16", will make much difference in amperage output.
    I'm now wondering if the extended core on the front was a mistake.
    Can always turn the coil around the other way, as the back side is just about flush with the bobbin material.
    Think that's the next step, turn the coil/core around, so the rotor magnet flux, can sweep through the coil/core closer.

    Then again, your core is miles away from the coil, will have to ponder this.
    peace love light

    Here is the data for mine. 29awg wire 55pound magnets @ 1/16"
    gap against 3/4" X 3/4" core block. Output at 3000 rpm's = per
    strand of measurement. 1 Strand 50 votls @ 170 foot.

    Each strand 170 feet X 17 strands = 900 volts all open circuit readings.
    The wire is rated at 600vac bye bye coil.

    Same setup gap at 1/8" output 450vac with barely any speed up under
    a loaded condition, Like I said you will learn the importance of
    building with high tolerances. The tighter gaps and the stronger
    magnets stress out a poorly built platform. Use a shield to hide behind.

    Wooden wheels with popped in magnets might come out if gaps are
    tightened up so be careful SKY.

    Hi all, made a few more tests today.
    Changed the pulley configuration and set it to maximum 3070 rpm.

    Each power channel now gives 130 volts AC, coil open circuit.

    Then wired both channels in series for 260 volts ac.

    Tried a 25 watt 120vac, incandescent bulb and it shows 10 volts ac across the bulb.
    Input watts do not change, though hardly any power is being drawn by the bulb.

    Think something is wrong with this setup so far.
    Can the magnet to core gap be the problem, it is at 1/8" gap at the moment.
    On one power channel, the 6 watt led bulb lights up nicely, though with an increase in watts.
    Hmm, will have to give this some thought.

    Hi lotec, you're welcome.
    peace love light

    Thanks SkyWatcher for sharing test results. Ive been curious for some time about these types of coils.

    Thanks Dragon, that looks like nice work.

    Wrong thinking and wrong direction as per the cloudy usual.
    Shorter wire, more power per mass, old rule. Old thinking, bad
    suggestion as always.Max drag like Bi

    Hi Sky,

    Nicely done. I am curious to see tests with coil, OC and loaded, with and without the magnetic neutralization in place. Also for your own benefit, try running the power channels in parallel. Standard theory says maximum power transfer occurs when load impedance is equal to the coil impedance. Also note that temperature rise will increase coil resistance, significantly.

    Thanks,

    bi

    Not sure what to make of this so far.....................
    Yes I think this is right, increased RPM's to compensate for small rotor
    dia that translates to lower speeds of which the magnet passes the core
    material. This fact makes me want to change my 6" rotor build before
    it is completed to a 10-12" rotor but using the same weaker magnets.

    However I am going to try it but being prepared to add more feet of wire
    (More Strands) to make up for the slow speeds for each channel. This is
    why I have 3600 feet of #25awg on my coil.

    My suggestion is to keep on experimenting with this small setup til you
    have maximized the output. This means getting 100volts and enough
    mili-amps to power up a load while seeing to it that no increase to drive
    power takes place.

    Magnet to core gap

    Rpm increase

    Added number of strands.

    This is where you find the limits of your mechanical contrivance. Tight
    gaps against (Nearly) very strong magnets are harder to build but with
    an opposing magnet to do away with all of the cogging who cares, right?

    It is under these circumstances that you produce much more power.

    Keep at it you will learn much from your machine. Spend an equal
    amount of time testing as it took you to build it.

    Have you tried 15, 16, 17...........24 strands...........26 strands?

    Time to party.

    Not sure what to make of this so far, though think the rpm needs to be increased maybe.
    Can also change the rotor magnet polarities, back to north-south-north-south, as the magnets are not glued into position, they're only press fit and magnets attracting each other, that are holding the magnets in the rotor, seems ok so far.
    Thoughts appreciated.

    You make some interesting points.

    I hope you don't mind me asking but that looks like a nice piece of hardware to work with. Only if you can spare the time.

    The hardware with the windings, i'm assuming it's the stator. What is it off. or is it custom built? How are the individual cores attached to the rim piece, or how do you get them off for winding? And how are the magnets attached to the rotor. I'm probably being a nusence, and some tricks of the trade are hard earnt, but if your feeling generous that would be cool to. Not too much detail required. I will get the gist.

    regards

    Edit... Good luck SkyWatcher, I'm hoping you can get good juice out of that coil.
    This is Sky's thread so I'll keep it brief... This project was a quick and simple conversion to prove a point. The core is from a standard box fan with all the wires cut off and rewound for the testing I wanted to do. The center is a machined steel core ( machined for the bearings and mounting) mounted to the backing plate. The rotor was machined from plastic with the iron pole pieces glued in place. The pole pieces direct the flux through the core as it rotated. Even though it worked very well and it was very efficient I didn't consider the added efficiency difference over a standard alternator to be great enough to pursue. I later built a large conversion using a donor 3kw gen head which worked ok but again the efficiency gain wasn't much over the standard off the shelf units so I moved on to other ideas and thoughts of how to increase the efficiency in other ways.

    Anyway, neither here nor there...? Are you kidding? I didn't know all
    that, you are an awesome builder. Glad to see you working on lower
    lenz.

    Anyway, neither here nor there...? That is what I came for, keep blowing
    your horn like that, it's what I love to hear.Yours is a bit different as
    you say but this is how we combine ideas to further the work.

    Hi all, Hi turion, thanks for sharing all the information here, even if you already did elsewhere, it is appreciated.
    Like was said, the simple one core test, can hardly be conclusive.
    Have not even tried tweaking the setup further yet, as bromikey says, this setup may not be ideal at the moment, to show the magnet to core neutralization effect properly.

    Will work on tweaking the magnet neutralizing method at some point, though the next step, maybe tomorrow, will be to get the coil/core in place and run some tests.

    It's just me using the shock treatment. Dude there are no spaced core
    strategy used here. That is the Muller motor that does that. If we were
    using properly spaced cores you would still have lots of drag without
    using Muller's coils and circuits.

    No offense Dragon

    However we can't keep mixing up apples and oranges in the details. A
    little misinformation in the lump spoils the whole thing. Please keep
    a strict eye on the specific layout and I won't feel the need to continual
    correct you.

    It is my desire that you understand. Is it yours?

    Best way to grasp this easily is buy some refrigerator magnets that
    are weak and cheap, then use a lazy Susan from the kitchen that
    is used to spin around in a corner cupboard so you can get the cups
    behind.

    Now you have a spinning wheel and hot glue the magnets on that.
    This will get you to magnetic cancellation by following instruction.
    Very very simple setup.

    First (Like Mad Mack taught) measure the pull force it takes to over
    come the lock using 1 magnet on the spinning wheel to a bolt or
    something iron. This is the first step.

    Repeat this step again using a repulsing magnet on the opposition
    side of the 2 rotor magnets to help break the magnetic lock.

    Now you have your answer.

    The taunt is all in fun to see whats inside.

    God Bless you Dragon.
    Thank you, we should be able to have a reasonable conversation even if we disagree on different points.

    I'm well aware of the forces involved, I've been building these machines for a few decades now. I have a large unit that will rip a 60 lb flywheel right out of your hands and uses custom made N52 neos. I used to sell a 3 phase radial air core alternator kit that would produce 500 watts and fit in the palm of your hand. Anyway, neither here nor there...

    I believe your thinking of something a little different when I made the statement of spaced cores. I'm simply saying that because there is a gap between each of the coil cores there will be a significant cog moving from one to the next. As the cores are moved closer together this becomes less of a problem. An example shown in the generator below of one I built a few years back to remove or lower the Lenz effect. The coils and magnets in this case were stationary and only the pole pieces were moved. Shorting the coils had no effect on the torque required to rotate the rotor. Although a different design it's very similar to what Turion is doing. ( and, no, it is not overunity just very efficient )

    The other comment I made about the neutralizing magnets after the coil started generating power... the best way I could explain it would be to look at Fig 9 on the link that Turion posted... When there is no load on the coils (44) the polarities shown are canceling each other, however, when the coils are loaded the core's (50) will reverse polarity as the current increases. Now you have 2 forces acting against the prime mover. With the cores side by side the start up and running torque is minimal.
