KMD - Kehyo's Magnetic Disruptor

[kEhYo77]

Hi.

As of 11.1.11 I am starting my new project of a motionless electromagnetic generator. I will be disrupting magnetic field of a permanent magnet placed within a Rodin coil wound on toroidal core made from ferrofluid. This core material will provide almost no hysteresis lossess to a high voltage pulse and it will respond to high frequencies of switching carrying magnetic mometum along the N-S axis and at 90 deg. around the toroidal core... I'm going to make ferrofluid first and then I plan to construct the core's shell from fiber glass stripe and some resin to form multilayered laminate on a wax donut model...

My logo for this project incorporates the starting date and somewhat resembles the device... :]_.o0



OK. So, here it is:



The idea is as follows: when a Rodin coil is not being energized the magnetic flux is focused within the closed loop core (4), fixed around a permanent magnet (1). When a Rodin coil (2) is energized it creates a twisted magnetic field gradient around it and saturates the donut core inside (3) at 90 deg. angle. It affects the closed loop core in such a way that the field from a permanent magnet now has to find some other route. The inner part of a Rodin coil (wires close to the permanent magnet) creates magnetic field of the same orientation as permanent magnet's field. So those two vectors add up an now the lines of force go through the core in the shape of a triangle with a powerful magnetic momentum, inducing voltage in the output coils (5) of that core. Then we stop the current flowing through a Rodin coil and the system seeks equilibrium state finding the shortest routes to balance itself. Closed loop core's particles rotate back 90 deg., which induces voltage on the output coil (5) around the outer edge of a Rodin coil.

I might not be understanding what you are saying, but fiberglass and epoxy
do not usually work well together.

Don't worry, a friend of mine makes laminated crane cabins, I don't know the kind of binding agent I am going to use but it is not a problem. I am in the process of modeling my device in 3D so you will see what it is about soon.

So what do you think about it? I might generate some unusual effects at resonance.

So what do you think about it? I might generate some unusual effects at resonance.

Can you explain your thoughts on the purpose and workings of the permanent magnet? Which coils are the input/pulse coils? Have you taken into account that the Rodin winding forces 1 pole to be entirely tucked away in the center and the other all around the outside? Did you know the clockwise or anticlockwise orientation of the Rodin coil affects the polarity? Do you intend the ferrofluid to maintain and build momentum, or periodically reverse direction?

I like the look of it, but you didn't tell us much about it's intended operation.

I plan to make an animation on how it works in near future but for now I will try to explain the workings of this device the best I can (English is not my native tongue...).
I got fascinated with the simplicity of MEG type generators and I wanted to improve on that. I came up with an idea as how to overcome some of the shortcomings of T. Bearden’s solution. The prototype somewhat worked but the switching mechanism for redirecting magnetic flux was not efficient. So I left it for a while. Recently I got this brand new idea of redirecting the permanent magnet flux path. J.L. Naudin’s improvement on MEG was the introduction of thin N-S field across the core, at 90 degrees to the lines of force going through it, which effectively cuts off the magnetic flux path with much less energy than the original design. This cross-path flux stream blocking is used in US 4,006,401 Patent for example. At first I wanted a generator based on one permanent magnet only to make things simple. Looking at pictures of how ferrofluid sticks around a permanent magnet I realised that the optimal C shape core for closing the path between the poles would be a thick shell encasing the magnet. The volume of ferrofluid picked up from a bath by a permanent magnet indicates the proper volume of the shell type core for that magnet, meeting the requirements for closing the loop with minimal leakage outside the core. The cavity inside the Closed Loop Core, contains Rodin type coil fixed around the permanent magnet. It is not the ‘original’ Rodin design. It will be bifilar, but in the same direction (Tesla style for electromagnets). One of the purposes of this coil is to effectively magnetise a part of the shell core at 90 degrees blocking the passage of permanent magnet’s flux through its volume. Looking at the outside edge of the Closed Loop Core I have to deal with relatively thin wall (because of the distributed cross section volume at a given radius). Now, I am going to use the peripheral part of the Rodin type coil (only half circle part of outside facing windings) to influence the magnetic vectors in this area of space. I could achieve similar effect witch a standard toroid coil, (similar to ORBO) but in this solution, the Rodin type coil besides providing the effect just mentioned, creates a strong magnetic dipole in its centre, parallel to already existing field emanating from a permanent magnet. The coil should be wound in a proper direction to create magnetic pole of the same polarity as in magnet. This configuration of two like fields in the same direction will have now a greater magnetization potential in the N-S axis of a permanent magnet, than the magnet alone would have. So to sum things up, by pulsing the Rodin type coil we effectively create high magnetic resistance in significant area around a permanent magnet forcing its flux through alternative route (through the core connecting all the magnets in a loop). It is similar to the pumping of a heart. At this instant randomly oriented particles of ferrofluid, which retain no magnetization will align to this strong presence of a magnetic gradient in this triangle output coil core. The main power of this combined magnetic impulse will come from a permanent magnet and the current induced in those output coils will have negligible effect on the input current in the Rodin type coil. There is another set of output coils placed around each disruptor on the swiching section of the Closed Loop Core. Without the Rodin field present magnetic particles orient on the N-S axis again rotating back 90 degrees inducing potential I these windings. I am expecting some translational movements within the donut ferrofluid core of the Rodin coil. I am not sure of the effects it will have on this configuration. Hope it helps.

Because one picture is worth a thousand words...

I built this today... It is a beta version ready for testing. It lights up 2 ><LEDs at the 2 output coils when 12V is applied to all 4 input coils at once. This indicates that the output core section magnetises and demagnetises while pulsing DC in one direction only, which is a GOOd sign! There will be strong kickback from 4 input coils when the magnet closes the loop after the pulse. What is interesting at this moment is that when input polarity is reversed it still lights up those LEDs...

Today I started building a new configuration. The one in previous post was my first try and I had to make few adjustments. I salvaged two more ‘transformers’ from broken PC power supplies. It appears that many of them use similar components, so I have enough identical core material to work with now. It is quite hard to rip apart the coils but it is doable. I came across 2 different shapes of core pieces: C and L. Both of them have little slit in the shape of a triangle, right where my DIY bobbin is positioned. I filled that with powdered iron mixed with epoxy to fill this space.

The input coil this time will be wound close to perfection when it comes to geometry. I will be using two layers of wires, 16 wires per layer to form 3D Tesla bifilar pancake electromagnet. I think that the best way to connect all those wires is to make 2 interleaved sections 8 wires per section soldered together for handling high current. So it is going to be two multi strand isolated cables per section making sort of a bifilar tape. I will have two such tapes obviously to make pancake coils. I predict high efficiency and quick magnetic field build up as a result of this configuration.

Today I was browsing through google patent database and look what I've found:
Magnetic Power Converter
it looks like this one is based on my idea from Feb 2011, what do you think about it?

Basically all boat hulls (fiberglass) are made with fiberglass mat and epoxy so I'm not sure what you are referring to there AFAIK that's essentially to core ingredients for most boats as well as fiberglass car bodies (like Corvettes had when the dropped the metal bodies).

Looks close enough that you might want to write the patent office to let them know this is open source or that it is prior art.
