  • Switched magnet solenoid



    I started working on this project about a month ago. This concept was hatched from my work with the MEG. I realized that in order to generate any power, there had to be some movement associated with the device.
    Like any new idea, the concept and realty have to be reconciled through construction and testing. This takes a lot of time and energy. Nevertheless, preliminary results are encouraging so I thought I would share what I was working on.
    A neodymium magnet is nothing but a perpetual energy device, but getting power from it without wasting a lot of energy is not always easy. I think the trick is efficiently turning the magnet “on and off” in order to use it. To do this requires a way to recover the power used in switching.
    A transformer is exactly what is needed. A transformer orients the magnetic domains in its core depending on the polarity of the current traveling through the primary winding. This energy is then transferred to the secondary winding in a highly efficient manner. A bifiler wound coil fits the bill nicely, although adjacent coils will also work.
    All I am doing with the switching coil is reorienting the domains of the core in opposition to the magnet. This essentially turns on the magnet by blocking the flux path between poles. The only work being done by the switching coil is in the hysteresis loss. All the rest of the power used in the coil is available for recovery.
    I have two devices that I’m currently working on. One is a solenoid and the other a rotating unit. The solenoid is very interesting to me, although the rotating device will ultimately be far more efficient.
    I have tried a number of configurations for the solenoid. I tried a coaxial configuration similar to the Hilden-Brand electromagnet, but it didn’t switch efficiently (see below).



    Moving the control coil 90 degrees, and closer to the magnet, helped actuate the core.
    As the core is pulled into the magnets it becomes polarized. The act of a polarized core traveling past a coil will generate power. If a coil is wound around the core just outside of the solenoid, power can be collected. I haven’t got quite that far yet, but it’s the next step.
    Eventually I plan on having two solenoids set up in a pull/pull configuration with a common core. Between the two solenoids I’ll place a pickup coil around the core. How much power it will generate is yet to be seen.
    Power is also generated in the steel surrounding the poles of the magnet. Current is induced back into the switching and recovery coils as a result of the movement of the polarized core. How much is also yet to be determined.
    Here is the front with the core in:



    Here is the center without the core:



    There is still a lot of testing and development to do but I have a fairly solid idea of what I want to end up with. The solenoid could be used as part of a motor, or a small generation unit, but I think a fully rotating device (still working on it) will be better. I'm going to try and get this solenoid to oscillate using a mechanical switch and a spring, although electronic switching will probably work better in the long run.
    There are hundreds of ways to reconfigure this type of device. I think of a new way almost everyday, but I have to stick to something. I think the concept has great potential so I'll be traveling down this road for a while.

    Cheers,

    Something, what is growling in my Stommach since i think about your Attemps, was, that you should not oversaturate the Core.

    This Guy, what did make some Experiments with a Torroid, Magnet and a Coil on it,
    said, the Core behaves like a Transistor, when you saturate the core.
    His Name was K Meyr, but not the one who have the Theorie about Scalarwaves.
    When it start to saturate, the characteristic curve goes up to a certain Point,
    change to a flat Line, and there is no different at the Output/Strenght from the Magnetfield at the Core anymore.
    He had to change the Magnets to weaker one, that they match better, and he could get better Results.
    And he had to drive his Device at the Limit from Saturation,

    I suppose, that he did not 'close the Circle' with the Magnetfield from the Magnets, but with the additional pulsed Coil he did.
    And that is, how you get more Induction into the Core as only with the Coil.
    I think anyhow, its a similar Way at the MEG, that he creates a Magnetfield with the middle Magnets,
    and close the Circle with the other Coils.
    And thats the Limits too, what seems there is, when T B talks about 200-800W? Output,
    as if there is the Limit with the Core and the strenght of the Magnets, similar to a Fluxfieldgenerator.
    Theorizer are like High Voltage. A lot hot Air with no Power behind but they are the dead of applied Work and Ideas.

      Thanks for the info Joit. I'm not too worried about core saturation characteristics yet. I'm basically just switching the magnets on and off and letting the magnets do the mechanical work.

        Very interesting....

        Hi Ted,

        Very interesting idea.....

        A few questions so that I can replicate if that is ok?

        What is the material of your push rod/center rod?

        How are your coils wired? In series or parallel or some other way?

        What is your power source?

        I have been thinking about this for a while now as an alternative simpler way to replicate the voicecoil part of the kundel motor....

        Thanks for any and all help...


        Tj

        P.S. You might find this Bedini Back EMF Motor Generator patent interesting....

          Hi Tj,
          Of course you're welcome to replicate this device, as is anyone else. It's a simple thing to make and a lot of fun to play with.
          These pictures are of some of the early models I made. I was trying to determine the most efficient geometry, which turns out to be the square keeper.
          The plunger is a piece of 3/4" mild steel round stock I bought at the hardware store. It fits just perfectly through the middle of the magnets, which are .76" in diameter.
          The steel surrounding the magnets is 2" x 3/8" bar stock, but you can use layers of thinner material to do the same thing.
          The coils are something I'm still working on. I'm trying to get just the right size wire, at the right amount of turns. A neodymium magnet has about 1.2 to 1.4 Teslas of force at its face, which is a lot. To generate that kind of force in a coil requires about 10,000 amp turns! Fortunately it doesn't take that big of a coil to effectively switch the magnet, but they need to be considerable bigger than the ones in the picture.
          I'm winding a new coil today and I'll post the results in the next day or so. I'm trying 22 ga instead of the 19 ga I was using. If the wire is too small, it takes a higher voltage to make the switch. I have a 50 volt supply, and could gang a few supplies together, but I would rather keep the voltage down. What voltage / coil combination is the most efficient is still an unknown. These are the variables that take time to work out.
          Nevertheless, a decent size coil and the right voltage will make it work. I want to get a working model first, then start tweaking it.
          Thanks for reminding me of the Bedini BEMF machine. That motor has great potential. He said one time that he really runs it with the rotor magnet reversed, which made sense to me at the time, but not anymore.
          As it is now, the rotor would be strongly attracted to the stator with no current through the coil. As soon as the rotor needed to pull away to keep rotating, a strong pulse would activate the control coils to reverse the polarity of the stator rods. This would block the effect of the stator magnet while changing the polarity of the stator poles around the rotor magnet. The change of polarity would then push the rotor magnet away from the stator. You would have a pull/push action on the rotor.
          The more I look at this motor, the more I like it. All the current generated by the rotor magnet passing the stator poles, plus the recovery of the control pulse, would be captured in the output coils and returned to the load. It could truly be a self running generator (which is really what I'm trying to do here). Maybe it would be more worthwhile to replicate Bedini's machine? LOL

              Where can I find your comment explaining why it did not work?
              It came up under "live2laugh111". Is that you?

                Hi Ted,

                On the Bedini BEMF bar motor what is 19a and 19b?

                Are those "magnetized pole pieces" magnets? Any thoughts....

                Take care and have fun....

                  Those are just soft iron pole pieces. They get magnetized from the stator magnet and pull in the rotor magnet. Once the rotor magnet is lined up between the pole pieces, then the control coil fires, reversing the polarization of the poles, which then pushes the rotor away. This is a Lenz free motor, among other things.
                  The rotor magnet traveling past those pole pieces generates electricity in the output coils, which is then fed out to the load. The output coils also induce most of the control pulse, which is also fed out to the load.
                  If there is any device that could have the potential to run your house, this is it IMHO.

                    You see the latest is signed with Ted, so..? i would suppose, he did write his comment there.

                    About the MEG, it was mentioned oftens at more Threads around here,
                    but noone was really exited about, to rebuild it or play around with it.
                    Anyhow, for most it does looks like, that it dont works. (so easily?)

                      Bedini actually said that the rotor magnet in his BEMF device should be reversed, but I like it as it's drawn.
                      I didn't understand his machine then as I do now. I think it takes less energy to release the magnet than it does to pull it in. A strong, quick pulse is all it takes to reverse the polarity of the poles and sent the rotor on its way.
                      The real work is done by the magnets attracting and moving towards each other. This accelerates the rotor and simultaneously generates power. This is all gravy since no external power is being applied at this time. Once the rotor magnet has reached a position directly between the poles, it just needs to be released.
                      The more speed the rotor has, the more power is generated. Two big neos have a lot of attraction and a lot of generating power. Since most of the release energy is going to be recovered in the output coil, what's not to love?
                      The interesting thing about the release pulse is that it's not doing any real work. There is no magnetic current draw as there would be in a motor. The magnetic current faces two like poles on each side of the coil and has nowhere to go. Consequently, the core quickly saturates and pulls no further current from the coil. The only "load" on the circuit is the output coil (besides the hysteresis loss).
                      I'm going to try and replicate Bedini's BEMF motor. I'm building something similar anyway, but I like his design better. I'll start another thread when I get started on the project.

                      Cheers,
