Canceling self-induction in electromagnets

I have been studying for a while the concept of canceling self-induction in electromagnets. This, in my oppinion, is the Holy Grail of highly energy efficient machines. The idea is to make an electromagnet be part of a LC circuit. At resonance XL (inductive reactance) and XC (capacitive reactance) are equal and opposite, so they "cancel" each other out, making the overall impedance the pure ohmic resistance of the conductor itself. This would increase the overall efficiency of the electromagnet assembly (be it in a motor or elsewhere). If you want to read more about this, patent US 512'340 is all about that (you have it attached) and also "The Inventions, Researches, and Writings of Nikola Tesla", "On electrical resonance" section of the book. 

I have tryed using all kind of motor electromagnets and capacitor combinations but I can't seem to attain the desired effect (canceling of self induction). There is allways higher than ohmic resistance impedance in the circuits. It is important to mention that I have used coil+capacitor assemblies with the coils having inductance of at least 50mH (Examples: 350W Three phase induction motor coils, 100W Monophase induction motor coils, relay coils, etc). I say this because Nikola Tesla in US 512'340 made the capacitor, part of the coil itself, thru a very interesting winding of it. I haven't tryed that aproach, yet. That should hold some promise.

Anyway I write this  because I have hit a wall and I hope that toghether we can pass thru it.

P.S.: Fighter, is there a day/night luminosity mode on this site? The white text on dark background is hitting my eyes hard. Thank you.

Unfortunately we don't have a night/dark theme, we didn't had time to work on multiple themes when we built our site, we created just this theme.

We needed to build it fast and bring it online so our team can have a home and a platform for continuing our research and have all the necessary features for exchanging/sharing ideas, experiments, photos, videos and documents.

But I recommend you F.Lux, it will auto-adjust the luminosity on your screen in the evenings and nights. I use it on all my machines.

Maybe I can add on my to-do list a option for having a option for members to choose the color of the text but I need to do some research on how I can implement this within the existing code of the site (which is based on the MVC-Forum platform but heavily customized by us and containing our own implemented features). It's not going to be a fast implementation and, considering the lack of time, I don't know when I'll be able to implement.

Until then F.Lux or something similar could be a temporary solution.

Fighter

If You want to maximize reduction of self inductance, just wind the wire in the coil 90 degrees of each other turn - 45 degrees to the axle of the coil both directions one by one turn.

What do you mean 90 degrees of each other turn? I can't visualize what you are saying. A drawing would be excelent.

el_fuego333 posted this 5 weeks ago

I mean like this - blue wire on the photo. if you place the turns 90 degrees to each other, the magnetic field can not induce the back-bracking current , so the self inductance is zero.

Welcome El_Fuego333,

That is a caduceus/tensor coil and it's known for its unusual properties, one of them is the coil is producing scalar waves.

Summary of experiments conducted with caduceus-wound coils, also known as tensor coils. Key findings include: 1) The coils exhibited zero impedance unlike ordinary coils and did not heat up when powered. 2) They displayed infinite resonance, strongly resonating across many frequencies rather than just fundamental frequencies. 3) In some experiments, the coils appeared to levitate when pulsed with microwave frequencies, hopping slightly off the ground. 4) This device has shown some very interesting features concerning the transmission of these scalar waves through a shielded and grounded box. Standard electromagnetic theory cannot explain these anomalous behaviors, which seem to arise from the unique toroidal magnetic field generated within the coils.

One of the best researchers who studied this kind of coils is Wilbert B. Smith from Canada:

https://alixus.wordpress.com/the-caduceus-coil-2/

Also there are experiments made by J.L. Naudin with this kind of coils:

http://jnaudin.free.fr/spgen/

I'm not sure this kind of coil can be used as electromagnets because as far as I know it's converting its entire energy in scalar waves, it's some kind of energy sink:

The coil is said to be an energy sink — that is, current fed into it just disappears, causing no radiation, even of heat. When operating and placed near a grid dip meter, the coil is said to show a large number of resonance points across the spectrum from 200 to 2.0 Mc. This coil is further said to have zero impedance. Further, two or more coils cannot be coupled together. Also it has infinite resonance – unlike an ordinary coil which will resonate chiefly at its natural fundamental frequency and weakly on the 2nd or 3rd harmonic, the Tensor coil is capable of resonating strongly on any number of frequencies randomly spaced in the spectrum. The signal pumped into such a coil strangely enough cannot be quantified (detected) by standard RF (radio frequency) detection apparatus. Many “Ham” radio operators and electronic technicians who have used these coils, are completely baffled by them.

It seems to me that it can't produce a magnetic field but I may be wrong.

Note: researchers should be carefully when experimenting with this kind of coils, they should not stand in front of them as the effect of those directional scalar/longitudinal waves on living organisms is still unknown; please take all the safety measures when experimenting with this kind of technologies we're using in our research !

Fighter

Well, yes, but that implies that I space the windings more than a conventional coil. If I do that, the developed magnetic field reduces significantly and the efficiency also.

Hi Vasile,

I have read something you might find interesting recently. A guy on another forum shared he has made several OU prototypes by putting together a wheel with magnets, trigger coil and a generator coil (or output coil) that he wound up precisely to go into resonance at the desired RPM. If you want to power anything from it, you must include the load in the resonance computation too.

I hope sharing links to other forums is ok, I tried to look for some rules about that and didn't find any so please remove the link if it is against the rules.

Hi Kloakito,

No worries, the links to other forums are allowed here as long as those forums share the same goal with us and the subject of those links are about the same kind of research we're doing here.

Regards,

Fighter

hi all,

after reading through the papers which Fighter linked (thx for that) i decided to build myself such a coil. i took 12m of loudspeaker wire and wound this coil on a pvc pipe. it took me a while because the winding process is not so easy as i thought it would be.

i have an air-coil system which is in resonance and i put this type of coil near the system and watched the oscilloscope. what i found was the resonance signal of my system. so with this coil and in this condition here i can get a signal out of it.

the next thing i tried was to rectify that signal with one of my diode-plugs. and yes this works too - i can 'modify' this signal like we can do with 'ordinary' electromagnetic waves.

BUT

i was not able to consume this power on my load. i tried LED and ordinary lamp but this energy did not manifest itself in my loads. i cannot diminish this potential which by the way is in de capacitors. it seems that there is no current because when i connect a load i cannot see any effect. at the moment i have no idea what's going on.

here is a scope shot of this signal. CH1 is my main resonance dipole. CH2 is input from halfbridge. CH3 is one leg from caduceus and CH4 is other leg after rectification. the energy between the 2 curves is stored in caps for later usage (which did not work as i mentioned,,,)

 

hope that there will be light somewhere

regards

B

I have talked to Turion aka "David Bowling" in the past regarding the exact same thing that you posted and honestly not much has come out of it. He talks about a generator that puts out 1400-1600 watts on an input of less than 300 watts. I would like to see it with measurements being done on it. There is nothing like that posted.
