Combining Magnetic Frames

This is just a suggestion and has not been built and tested. First, watch the very interesting video here where it appears that a ferrite toroid with small magnets on it is one way to reproduce Lawrence Tseung’s magnetic frame:

While this would be a very easy video to fake, considering the Tseung frame performance, I am inclined to accept this one at face value. The Tseung Magnetic frame has been independently replicated at COP=1.5 which is, 50% more power output than the input power.

One obvious arrangement to test is cascade frames as shown here:

The limit here is the magnetic saturation of the laminated frames or “yokes”. While you can do all sorts of calculations to predict what power levels can be carried by any laminated iron frame, all that is really necessary is to look at an existing transformer and see what power rating is quoted for that particular frame cross-section size, and although the power levels shown in the diagram are very modest, it is likely that very much higher power levels could be used, giving a much higher excess output.

Laminated iron has very restricted operating frequency, typically, well below 1000 Hz, which is why the diagram above shows just 500 Hz as the suggested frequency. As efficiency improves at higher frequencies, using ferrite for the frame and a higher frequency should improve the performance.

One additional step would be to use Thane Heins’ adaption for the frames as his performance gain is very much better with 300% being about the lowest noted in experiments. Combining these two ideas might produce an arrangement like this:

With this arrangement, the increased magnetic path on the right hand side of the first two toroids gives a dramatic improvement to their performance, even without the use of magnets on the toroids. A COP of nine or more should be perfectly possible, but only actual implementation and testing will show the real performance and testing far outweighs theory and ideas. Wound with coils, the arrangement would look like this:

The input would be pulsed with a 555 timer circuit or a signal generator. Power limit is the magnetic saturation point of the toroids as you have to keep below magnetic saturation or else your pulsing will not have any effect. Avoid the resonant frequency of the ferrite toroids, but pulsing in the kilohertz range might give a very good results. There is, of course, no reason why you could not use more than one of those arrangements, combining the outputs after rectification and feeding into a capacitor:

This could be an interesting project. You will notice in the video that the brightest light is where the second magnet has not been turned around all the way to where the demonstrator finally positions it, so experimenting with different magnet angles might produce better effects. The magnets can be held in place with super glue when the best positions have been found.

Theodore Annis & Patrick Eberly have produced a variation on this multiple-magnetic-path method which is shown in their US Patent Application 20090096219. They have opted to use a motionless reluctance switch which is a solid-state device which can block magnetic flow when energised. They have arranged one of their devices like this:

The ring shown in grey is a magnet which connects to the ring shown in yellow through two diagonal ‘reluctance’ (magnetic flow) switches. The yellow ring can carry magnetic flux and the control box marked 118 switches the diagonal strips on and off in turn, causing the magnetic flux to reverse it’s direction through the yellow ring. The coils wound on the yellow ring pick up this reversing magnetic flux and pass it out as an electric current. While only one pair of rings are shown here, the design allows for as many rings as are needed to be connected together as shown here:

The patent says: “The currently preferred motionless reluctance switch is described by Toshiyuki Ueno & Toshiro Higuchi, in their paper entitled “Investigation of the Dynamic Properties of a Magnetic Flux Control Device composed of Laminations of Magnetostrictive Piezoelectric Materials” – University of Tokyo 2004. As shown in Fig.4, this switch is made of a laminate of a Giant Magnetostrictive Material 42, a TbDyFe alloy, bonded on both sides by a Piezoelectric material 44, 46 to which electricity is applied. The application of electricity causes the reluctance of the piezoelectric material to increase.

  1. Asking questions are truly fastidious thing if you are not understanding
    something fully, however this piece of writing provides fastidious understanding yet.

  2. Good post. I absolutely love this website. Continue the good work!

  3. Congratulations on possessing certainly one of one of the vital sophisticated blogs Ive arrive across in a while! Its just superb how a lot you’ll be capable of think about away from a thing mainly simply because of how visually gorgeous it is. Youve place collectively an incredible weblog site space –nice graphics, films, layout. This is definitely a should-see web site!
