    My new rotary attraction motor.
    Special thanks to Tom Bearden, John Bedini, Peter Lindemann, Joseph Newman, the late Bruce DePalma and all the others for the inspiration.

    3 sets of 4 coils in series connected n-s-n-s.
    Timing wheel and timing ajustment ring all integrated.
    At 50v runs on 550ma at 4000 rpm. No heat.
    At 160v runs on 1amp at 12000 rpm. Only heat from bearing friction.
    The spikes from collapsing fields are over 3000 volt.

    By the way, this is a modified dishwasher motor 1700 rpm at 1.4 amp.

    Hi Robert,

    That is good news

    I'm not a fan of wave shaping to get the spikes down - but when we are experimenting sometimes it can help isolate the problem - at least if that was the cause of the failures it could keep things running long enough to pin down the cause.

    I'm glad that you were able to spot the feedback and get things separated out.

    Cheers!

    One way to control the peak voltage of the spike is to widen its discharge time. Very narrow discharge times result in high voltage spikes. The faster a transistor "turns off", the higher the spike can be. Of course lingering the on time can have the negative effect of back attraction.

    You may wish to wave shape the gate signal so that it turns off earlier, but the trailing edge is a bit sloped. A word of caution here is that while that will help reduce the HV spikes, it will increase the heat in the transistor because it tends to operate as a resistor for a longer period. It is for that reason that most MOSFETS (if you are using a MOSFET) are switched as fast as possible.

    If you are willing to share a schematic, it may show up some areas that can be improved on.

    Hi Harvey
    I found the source of my problem!
    My ground wire for the 555 and the one for my fets were too close and
    causing induction with each other. So I made the two circuits separate
    and I used opto isolators and shielded wire to connect them.
    Now the motor runs smoothly at 750 rpm.
    There's still a lot to be done.
    I'm on vacation in florida so I will get back to it in a month.

    Hi Vince,

    Your MOSFET is triggered by a gate voltage that must be several volts above its source voltage.

    From what I can see, when you try to turn on the transistor the source voltage raises up to about 4 volts which diminishes the differential between it (the source) and the gate.

    Let us try and rewire it so that it is switching the ground side instead.

    Supply (+) >> Coil High Side >> Coil >> Coil Low Side >> Mosfet Drain >> MOSFET >> Mosfet Source >> Supply (-)

    Then your 9V (-) should also be tied to the supply (-) as reference.

    Now when your photo transistor supplies the gate with a signal, it will always be relative to Supply (-) and the MOSFET will turn on completely (with about 8 to 10 volts). A gate to source voltage of only 7V will never reach much more than 4.8A with a 10V supply according to the charts:http://www.radiotechnika.hu/images/IRF510.pdf

    Rewiring it as stated should solve your problem.

    Having some troubles with my rotary attraction motor

    Hi All,

    I'm having some problems with my rotary attraction motor circuit. When I power the motor directly from the power supply the rotor is attracted quite powerfully to the armature. I have a phototransistor switch set up that trips a FET that is supposed to delivery the 12V needed to drive the motor. However at most I am only getting 3-4V. I'm not an electronics person so I could use some help in this circuit.

    You can watch this video to see the problem Rotary Attraction Motor - Lindemann - YouTube

    Many thanks,
    Vince

    This is my Rotary attraction motor experiment.

    14 inch diameter
    Two 8-coil stators and two rotors.
    Each coil is opposite polarity with the next.
    All 8 coils on each stator are 400 turns tri-filar #24 awg connected in parallel.
    Total impedance measured for each stator is 0.9 mh .
    The 2 rotors are offset by 22.5 degrees and fired in sequence.
    Optical timing with pulse duration controlled by 555.
    Driving voltage is 15.5 volt.
    Giving out spikes over 1300 volt,blowing up 1200volt 595watt transistors.
    Using a 100 watt bulb to control the spikes and protect my circuit.
    anything else I try i.e. 2000volt capacitor,battery, results in motor stopping and circuit going in strong oscillation
    with light bulb very bright.(probably higher voltage.)

    Your input would be greatly appreciated if you can spare the time.

    Thanks

    You could try posting this on the Lockridge device thread or Electricity's Watson
    Machine thread. Since those threads are more active right now and are also motor related. Someone with more experience than I have should be able to help you.

    Peg motor

    Jetijs,

    Hello there. I was looking at your pics on the link you gave a few posts back and the first one caught my eye. On the thread "Resonance - nice and simple" Armagdn03 had posted information about a motor he calls the peg motor or universe engine. And the first picture you have looked like the same thing. I was just wondering if you have done any work with this idea or if you plan too?

    I've watched both electric motor secret videos, and just today finished this electric motor secrets thread. And I must say it's hard to focus on anything else during my day. Electric motors are interesting enough, several of you here have taken it to a whole new level. I need to go back through and make some serious notes. So thank you for documenting everything and all the input you have provided. To you too Peter of course for the movies and the guidance here in the thread. Great information indeed.

    I should be getting some things machined soon as soon as I get a solid idea of what I want to do, this peg motor being my first interest. And maybe this summer I can add a little to the thread when I have time to play and test.

    Armagdn03 I know I asked you about this motor on the other thread, and I know you are reading these, lol.. maybe this would be a better place to comment on my questions? Other post is "Resonance - nice and simple" post 46.

    Bob Teal Motor Is A No-Back-EMF Motor

    I am convinced that the Bob Teal Motor is a No-Back-EMF Motor, providing you provide a path for the transient inductive spike from the coil to go somewhere, for example, to a load or to charge another battery.

    Hello all,

    Thank you Peter for sharing this concept, and to everyone who shared their progress and ideas. Drawing from the info in this thread, and hopefully adding some ideas of my own, I would like to share my ideas. Hopefully the pictures will download ok.
    Picture 1, I like Peter's early concept presented in the video with the 4 opposing c-cores. This appeals to me because it uses the flux generated at both poles for motive power. It isn't as robust as the radial type motors presented here, but it is good for efficiency. The motor I would like to begin building will have adjustable stators. This will help in reducing airgap. It's just a cheap way to do it. The stator keeper pieces must be made of super strong plastic. A plastic made like G-10 would more than suffice. A tight weave of any strong cloth like fiber is dipped in epoxy and lightly squeegied. it's then laid up in a mold being careful of airbubbles. when all the layers are in place, a weight is set on top of a mold top piece that fits like a piston in a cylinder. This squeezes out excess epoxy. The result is a super strong part.
    The other part I am eager to build is the timing mechanism that consists of an engagement lever that can advance or retard timing. The pulse width and type can be adjusted by the sliding photo reflective sensor. Both functions can be controlled while the motor is underway. This saves a lot of time experimenting with different control parameters. I look forward to posting my results. If anyone has any suggestions on it, please let me know.
    I'm hoping the control circuit wont be too difficult to come up with. One similar to Jetijs's would work well. But I would like to only use one opto, so I will need to use a counter chip or something to split the signal into 2 outputs, 1 for each coil set. I found 1 photo reflective switch that may have high enough speeds, the toshiba tl907. Anyways, I will post when I have something done.

    So I start with iron core 1x1cm, lenght about 40 cm with cross rotor, two widdings for 200 loops. Input voltage 24V, current /measured with analog A meter/ 1,5A and RPM 3333 Then I found circuit what Jetjis and Mr. Lindemann drawn and I use it. RPM goes ut to 4000 RPM and currend goes to 1Amp. Then I try some experiments with pulsed optobridge.
    Hi

    I saw this post of yours, thought to tell you: USE MUCH MORE WINDINGS, as much as you its distance from your core material does not get so much, and then tell us about your results. My motor does not have much space in it for increasing the windings. each winding you add, contributes to the overall magnetic field, while decreasing the current draw, so you will have a much more efficient motor at the end. My Newman machine uses about 14kg of copper, and it is about 90% efficient. I can hardly say that it exceeds 100% but it is fairly efficient. Dr Lindemann's design has some advantages, and the main one is that it is BEMF Free unlike Newman's machine which turns really slowly, because of the LARGE BEMF, due to a rotating magnet inside a very large coil.

    And also, for reference, my Lindemann type of motor, is operated on about 50 volts, it draws about 0.6A and goes upto about 6000RPM, The mechanical efficiency of the motor is about 20-30% at best, and the recovery is about 50% at best. I suspect that increasing the windings can decrease the current draw, while, making the mechanical power output remains the same.

    GOOD LUCK

    Too bad the battery holders . . . I mean upright supports are not transparent

    Sadly, they are large enough to not only house a battery stack but also a motor to drive the axle. All that is needed in that regard is the energy addition necessary to lift the stator magnet out of the conservative loop.

    Because the cam would provide a gravity assist in normal conditions, it would have been good to see the device at rest with the cam down. If it truly worked as shown, without any momentum, it would settle calmly to a minimum point of gravitational potential energy balance with the magnetic fields. But if the rotor was driven by a motor, it would not come to rest in this way, but would begin bobbing as it tries to lift the cam against the gravitational minimum and finds its resonant position.

    Since these two conditions are avoided (transparent supports, natural state of rest) the video is suspect.

    That being said, I have shown with my M.A.P. tests that energy can be extracted from these two conservative fields when they are separated properly into non conservative parts. This device may exhibit such a separation. In my tests, mathematical projections showed there was approximately 10x the energy available for extraction than was required to drive the trigger mechanism. So while the output energy was minuscule, it was cumulative.

    Why has Roobert33 removed the video?
