Multi-Filar Coils

While making observations of coil designs that have been used over the centuries, I noticed only those that showed some perceived useful results were kept in the arsenal of the scientists, the rest were either ignored or forgotten. There are two basic types and a 3rd being the combination:

1 Circular – Eg Solenoid, flat spiral,spherical, toroidal, mobius

2 Non-circular – Eg Basket weave, geometric, polyhedral, star forms, mobius

The circular types have 3 basic types  a resultant 4th and the unique 5th type:

1 Rings adding vertically –  Solenoid Coil

2 Rings expanding diametrically  - Flat spiral

3 Rings adding in a circular form – Toroidal

4 Rings adding vertically and/or diametrically and/or circular

a) Conical – differing sizes in both direction

b) Multilayer Solenoid – same sizes vertically + differing sizes diametrically

c) Multilayer Flat Spiral – same coils sizes vertically + adding vertically

d) Toroidal and Poloidal windings mixed sizes vertically + differing sizes diametrically

e) Spherical rotations windings mixed sizes radially + differing sizes diametrically

5 Winding folding into itself, creating a single surface  - all possible geometries – Mobuis

The shapes of coils are one aspect the other is the winding order and direction, thus creating multiple poles, cross coupling inductance, retarding or increasing both the inductance and the capacitance as the design requires, the addition of the mobius windings diversifies the basic options, this is where the art is at in 2012. A good example of combining many geometries and winding types is the:

Magnetic coil(1820 Hans Christian Oersted)

Faraday coil(1831 Micheal Faraday)

Henry coil(1831 Joesph Henry)

Induction coil(1836 Nickolas Callan)

Ruhmkorff coil(1851 Heinrich Ruhmkorff)

Helmholtz coil(1869 Herman von Helmholtz)

Maxwell coil(1873 James Maxwell)

Cook coil(1871 Daniel Cook)

Tesla coil 1/4 wave(1891 Nicola Tesla)

Tesla Flat coil(1890 Nicola Tesla)

Tesla Bifilar coil(1894 Nicola Tesla)

Hubbard coil(1918 Alfred Hubbard)

O’Leary Coil(1920 William O’Leary)

Hendershot coil(1928 Lester Hendershot)

Interceptor coil(1946 John Wiegand)

Tokamak coil(1950 Oleg Lavrentiev)

Stellartator coil(1950 Lyman Spitzer)

Smith coil(1952 Wilber Smith)

Fusor coil(1964 Philo Farnsworth)

Hooper coil(1968 William Hooper)

Rodin coil(1986 Marco Rodin)

Biaxial Poloid coil(1990 Bo Atkinson)

Tetra Helix coil(1991 Bo Atkinson)

Vortex coil(1992 Ken Gailey)

Double Helix coil(TM) (2007 AML)

Not to mention my own explorations in coil geometry with:

Mandela coil(1990 Arto Heino) – Page 55 – Link

Crown coil(1994/2011 Arto Heino) – Link

Infinty coil(1993/2011 Arto Heino) – Link

- and many toroidal/polyhedral mixtures that have been popping up regularly with names like the Star ship coil, Loohan coil, Polish coil,  Big Secret coil, some of these are marvels of artistry and human innovation.

Not to mention the many non inductive windings that are used as resistances. This has been looked at for at least 200 years, Nicola Tesla was one engineer/Scientist who’s original thinking left a legacy of numerous winding geometries he used to design his motors and coils,one of these is his Bifilar design. This design exposed a unique addition to the idea of combining the merits of both coil and capacitor without addition hardware contrivances, the anti-series winding nulls out self-inductance.

Nicola Tesla writes that a standard coil of 1000 turns with a potential of 100 volts across it will have a difference of 0.1 volt between turns.
100/1000 = 0.1
A similar bifilar coil will have a potential of 50 volts between turns.
100/2 = 50
In that the stored energy is a function of the square of the voltages, the ratio of energy in the bifilar to a standard coil will be
50^2/0.1^2 = 2500/0.01 = 250000
Which as stated by Tesla, “the energy stored is 250000 times greater than the standard coil!”

The storage of energy when pulsing a bifilar coil is n amount more than a standard solenoid/flat coil, as Tesla stated and gave you the formula to engineer this type of coil, we should be incorporating this simple idea into many everyday devices. I have drawn a few design methodologies that I hope will spur this well known innovation into more interesting directions.

These are basic bifilar solenoid configuration showing the capacitance between each winding. The windings can be rearranged in a different order to change the amount of induction and capacitance you put into the coil.  The winding below shows what can be done to rearrange the capacitive differential to increase the energy storage.

The graphic table below shows how many different arrangements that can be used with a Quadrifilar coil system, each will give a different result for the inductance, capacitance and its resonant frequency spectrum.

A great science/engineering project or University paper for someone would be to tabulate and analyze  each arrangement,  you might just get your doctorate on this.

The flat coil is a dimension less than the solenoid and a lot easier to redefine into  multi-filar arrangements.

The basic geometries involved in designing coils, transformers and bifilar systems must have a few design rules so the engineering of these items become straight forward and adaptable to the needs of the energy transformations. Here are a few simple systems that can be easily expanded and used creatively.

The cipher I am using here is:

B = Blue              R = Red

U = Upper          L = Lower

N = North           S = South      / is the upper part of the cross

E = East               W = West       \ is the upper part of the cross

The order of the letters is the order from the top to the bottom.

The order of the numbers is from the left to the right.

The first set is based on 2 simple loops. This will give you 8 different forms:

The next is the topology of a single loop of wire which loops on itself, like a bifilar or just a plain solenoid:

As you can see by these configurations, the standard engineering practice used in industry only use a small portion of these geometries. Now if you loop 2 coils as used in transformers you will see industry only apply 1 or 2 of these geometries in 98% of all transformers.

The fusing of  Adams motor and the Tesla bifilar coil was one of the first iterations that showed me the correctness of this approach by its exceptional efficiency.

Incorporating both bifilar and loop transformations as shown previously, you can begin to appreciate the transformations I have below to create a magic square coil, as originally shown on my Artoworld website in 1999.

Old photo from 1999

Most of the original readers of these documents never understood my topology in 1999, even though I built many of these coil constructs as stators for pulsed motors. The current breed of experimenter has less inhibitions to these  geometric forms. The first arrangement is the non-magic numeric sequence, just the same as if you wrap a standard solenoid.

Colimag4

The next diagram is the magic square arrangement, which utilizes the the pairing of the “17″ as a magic square paring which translates to the bifilar pairing.

Below is the original stator coil I wound in 1999, it performed well and required high voltage(24v) and low current(0.001 amp).

I hope this small extract from my upcoming book “Talking with the Birds” will be helpful in any research you might be doing. Regards Arto

*** Update***

I have had a request to explain the Tesla/Adams Bifilar setup, here is a diagram that should make it transparent. The consequence of using this way of connecting coils will give you a multitude of possibilities for the experimenter to find interesting combinations ,  have fun regards Arto.

    hi artojh,,

    I will design a bifilar coil using ferrite rod to complete my final project. I need some journal about bifilar coil containing explanations, calculations and equations, benefits, and other detail stuff. Can you help me? is there a pdf file of the bifilar coil that you can share to me?
    thank you.

    Hi Ansyar,

    Thanks for asking, I am still working on getting data freely available to everybody for these particular types of coils. I have developed a method to test the differences and benefits to using this type and other types of coils, it is still in the drafting stages in one of my chapters in my book. Here is a run down of some of the tests and procedures that I will use.

    Build units

    Standard Coils 6 types (6)

    1 Air core solenoid
    2 Air core Pancake
    3 Ferrite Core Solenoid
    4 Ferrite Core Pancake
    5 Air Core Toroid
    6 Ferrite care Toroid

    Non standard Coil Geometries (6+6=12)

    1 Poloid
    2 Infinity
    3 Tesla Crown
    4,5,6

    Each standard/Non-standard coil will have each wound in: (10*12=120)

    1 Unifilar Start-End
    2 Bifilar Start-End-Start-End Connected as per Tesla Bifilar
    3 Trifilar S-E-S-E-S-E
    4 Quadfilar S-E-S-E-S-E-S-E

    5 Bi start-End-End-Start Connected as Low Inductance
    6 Tri S-E-E-S-S-E
    7 Quad S-E-E-S-S-E-E-S

    8 Bi Start+Start-End+End Connected as Parallel
    9 Tri S+S-E+E-S+S-E+E Connected as a Parallel Bifilar
    10 Quad S+S-E+E-S+S-E+E-S+S-E+E

    All the coils will maintain the basic parameters-

    1 Same wire Length
    2 Same wire Diameter
    3 Same amount of copper
    4 All Core diameters to be the same

    The Basic Tests will include (120 x 9 = 1080)

    1 Inductance
    2 Capacitance per turn
    3 Capacitance End to End
    4 Resistance
    5 Self resonant frequency
    a Spectrum Harmonic analysis
    6 Using 10 standard Frequencies
    a Spectrum Harmonic analysis
    7 Radiation tests
    8 Magnetic tests
    9 Electrostatic Tests

    Each Basic test will be performed with a second coil : (120×160 )+(120x120x160)x6

    1 Of the same type
    16 basic mutual inductance Geometries
    a 10 Different mutual inductance distances

    2 of each other type
    16 basic mutual inductance Geometries
    a 10 Different mutual inductance distances

    So as you can see for basic testing alone I would need 120 coils, wound in at least 6 different wire gauges, making 720 coils. Each of those coils would need at least 6 different winding lengths, making 4320 coils. Now each on these can have different basic geometries, like long verses short, another 6 more types, making 25920, whew !! that is just to start before I test each one in multiple methods.

    I am sorry that I do not have that sort of resources, basically a full laboratory with 3 to 4 staff full time working for at least 2 years, would be ideal. Alas I am but one man with no resources, I will publish all my results in my book “Talking With The Birds” ASAP, good luck, I hope some of what I have here can help, Regards Arto

      hi Arto,
      Thank you so much for your help,

      My final project is about water fuel cell (WFC) as it has been made ​​by stan mayer, dave lowton, and ravi. did you ever know?

      in their paper, there is mounting bifilar coil is connected to the WFC. They use x turn, y SWG, and z inch ferrite rod of bifilar coil. but they do not explain why they use the value of x, y, z of the bifilar coil. I do not find there a detailed calculation. it makes me confused.

      I actually want to know the benefits of a coil in a circuit. Can you help me to explain?

      I have learned that the bifilar coil consists of two strands of copper wire that acts as the primary and secondary coils. My question is:

      bifilar coil is the same as the transformer or not?
      what effect a given bifilar coil in the circuit?
      how the resonance effect, is that what is needed from the bifilar coil for the system? and what are the benefits?

      sorry for the many questions because I’m still an amateur in this case and sorry if my english is not good.

      thanks.

    Hi Artojh, I am working on a number of free energy devices and have a fairly good understanding of electronics and physics have wound a number of coils bifilar pancake solenoid quadfilar starship and believe you are truly demonstrating a great winding technique but I am Struggling to understand your diagrams am not sure if the numbers represent single turns or layers of turns and how it actually connects up. Was trying to work from the old coil pic on graph paper but the close up only shows a and b the chart shows up to d, the smaller diagram has 3 pairs ? up to c? please excuse my ignorance If you could make me understand how the winding all goes together I would be so grateful. am used to winding bifilar in series where two windings go on side by side at same time, so two starts two finishes. Start one is begining, finish one goes to start 2 and finish two is end. I can understand your first three diagrams where 1] you have a bifilar with two turns, 2] is a bifiliar with 2.5 turn showing capacitance and 3] the quadfiliar with 1.5 turns. If you could demonstrate with the same kind of diagram I should understand bear in mind i’m upside down here in UK this might be a drawback lol. Many thanks in advance.

      Hi Andy,
      Thanks for checking the windings in detail, most people never understood my methods in the early 90′s, so I decided to unravel the knot in diagrams. What I have on this blog is only part of a draft from my book, where I have also included earlier ideas such as the magic square winding. I am posting an update at the end of this blog with a diagram that should help you understand what I had originally designed. The arrangement possibilities are more numerous than I can indicate on my diagram. Thanks Regards Arto

    Wow thanks for amazingly fast reply, I look forward to exploring your posting, I know what you mean with explaining your own work I do all sorts of jotting down that I guess really, only I can know what it means unless I clarify it more but not everyone as you say is really interested. I came across your blog by searching google with “spiral solenoid starship spiral coil” as I was debating with myself what coil I should use next on my wheel pulsed motor / generator as I am getting a feeling that I may be able to get it self running with a little more work. Just the back emf from the drive coil I am using is quite exciting and I am hardly feeding it .01 amps on a constant reading with 12v supply. But I need more speed with little more current to get the generation working am using heavy magnets but unable to get much over 100 rpm and coils don’t start generating till its over about 200 rpm so luckily bumped into your work!

    Also Arto, the reference you have on standard solenoid looks to me like 4 layers of 4 windings piled on top of each other but always starting from same end of coil which is something I have never fully understood because my thinking made me think this was required but then noticing that most commercial stuff is wound back and forth and I read somewhere I think, that it did not matter as long as the windings were neatly following on. Its hard to find out what really is correct without trying everything as you say. Was toying with the idea of lots of pancakes piled on top of each other in series but, do I need litz wire, should they be multifilar, ? its just so much work for nothing if it does not prove better results. I had quite good results with a series bifiar pancake coil using 7 strands of .4mm magnet wire twisted in drill chuck for tapping off an induction cooker but not a definate cop>1.

      Hi Andy,

      Yes you are correct, you can wind it in either direction. The idea is to think about the actual placement, as each wire has an inductive and capacitive influence on all other wires, where the overall combination is much more than each part individually, like a living organism.

      The standard number sequence here would be slightly different if you wound it commercially as said, still the abstract Magic form would still be the same, it is the distance from each of the windings that will show up as unique harmonics adding to the open system with tunable elements to it local EM environment, also the inter-wing differential EMF’s are not uniform anymore. Magic Squares are like a form of controlled chaos.

      What is required is the free flow of the Ether through the coil system, using an organic wiring system, such as plankton growing from dilute chemical nutrients in its environment.

    hmm, not so sure now I actually look at it, you see on the solinoid drawings I can accept the numbers as being the turns in order but with the magic square it seems the numbers can’t be turns because if they were you would be having wires coming of for coupling before winding even one layer, infact a single turn then wire coming of each end which somehow does not seem right if it is and this is how it works then please tell me, but what I am thinking is there would be so much straight wire running over/under other turns that the magic would possibly be lost, I feel so silly that I can grab some but not all of it but I believe god loves those who try.

      Hi Andy,
      Remember all the wires are wound in pairs, the joining is at either the end of the coil. The numbers are also labels for the placement and location of each wire. I know this is not an easy design or system of winding, it took me years to figure out a new way of looking at coil engineering, then applying the abstraction into practical results. I suggest building a 4 layer 32 point connection board before tackling the Magic square wiring, the one on the blog I uploaded was a 3 layer 24 point connection board. The Magic square wiring is 4 layers with 2 input pair and 2 output pair which gives you 16 units of connections for each stator. The magic coil system was designed to have 2 stators which will give you 16 complete wire lengths that have multiple turns on each stator, which means each wire will represent one number placement on the magic square 4. I am sorry it cannot be simpler, good luck and regards Arto.

    That is wonderful, I feel quite sure I understand it now although I wanted to use just one coil if that will not work so well because they are designed to compliment each other I can add another but as I am using five magnets I would have to offset the second coil to pulse at the 3rd or second magnet. This might create an interesting unbalance to collect more from this. I was reading through quite a number of your other posts (impressed) my father is an artist, he is 87, I shall show him your work. Art and Electronics are often thought of as so separate yet it seems you have developed both complimentary.

      No need to sweat I have placed another diagram on my blog, completed as a magic square 4 system. Now you can choose from 880 magic square 4 arrangements. The rotor arrangement with 5 poles is OK with this coil system, or a possible expansion of this into a square 5 you can use the columns as each stator, this way you split the square into 5 parts.

    Arto, I am glad I am also motivating you. I have wound four bifilar layers was going to connect them as per corrected diagram but then started wondering what would happen with five or six layers and now you have given even more combinations I don’t have enough wire or cores to build every combination, much that it would be great to achieve that task! also you lost me again when you mentioned columns do you mean the 5 magnet columns .. no i doubt it. I wish we could meet to discuss this my email address is andy@makecleanpower.com although I don’t mind discussing most stuff here for the benefit of others who may follow this thread my original idea was inspired by romero uk’s variation on the muller motor but there appears to be so many variants on pulsed motors for high efficiency or even cop>1 romero uk by the way pulled out due to a visit from some well dressed people who were not happy and I believe posed threats as well as confiscating his equipment but you can still find stuff on his replication. Have read a bit on the adams motor to get an idea on the principals and can’t really get my head around the coils getting cooler as they run but believe so lets move on. I also don’t get the picture of the square properly either but I know how to use the connection system so unless you advise different before i start will wind another one or two layers then get following one of the three connection patterns but adding the extra 2 or 4 wires (1 or two layers) suddenly taking my mind back about 35 years to high school maths is not enough but am doing what I can. If I don’t achieve overunity, I may go back in time instead!

    I appreciate that add more layers could mess up the system but not knowing how it all affects itself exactly makes me want to experiment but i don’t want to miss the benefits you have already found. I read somewhere that with ordinary solenoid coils the best proportions is diameter = 1.5 X length i.e. short fat coils but then this is no ordinary solenoid. cheers Arto

    Just had an idea Arto, if we were to work out what way the current is flowing on each link it may be beneficial to wind the links into a few turn on an air-core coil, then position it so that one of the remaining magnets energizes each link in the right direction of current flow to encourage the pulse in the other 2 coils .. just a thought will test the original magic square first though have stuck to four layers as the wire ends were a little to much to increase on with first wind besides the connection of the magic is not as simple to add to as the first setup, am just starting my second coil.I will also need to modify my circuit so i have more control over pulse width.

      Your idea has great merit, this is the type of thinking that will get some interesting outcomes. This project will the hallmarks of originality and should lay a foundation for a different and unique design element that Robert Adams had hoped for my work in 1996. I am working on a pulse motor switching element utilizing the unique Lamda Diode, when my research is complete i will send you the diagram, it should work well in the magic square coil design due to its similarity of having a complimentary pair in reverse gate design.
