The bifilar pancake coil at its resonant frequency

[nelsonrochaa]

Hi MH , you talk a lot make me write a lot too and English is my third language so not easy answering to last big "testament".


"The central issue is what is the reason for taking a bifilar pancake coil and exciting it at its self-resonant frequency?Why do this? What are you trying to accomplish? What practical applications are there for this? It's fun to "play" but what is the point behind the playing? Those are the types of questions that are avoided and never posed and never answered by many experimenters. "

What i try accomplish have nothing to do with topic , i'm not talk about my own work,  but about  the topic that Evostars open .

"Here is another set of questions: Why a bifilar pancake coil? Why not a regular pancake coil? Does making it bifilar really do anything more than let the experimenter proclaim that there is a stronger electric field between the wires?"

Myself already answer about that point but i answer again :
Self induction of coil will be zero.  In a pancake bifilar coil  the magnetic field of one of winding is  equal and opposite to that created by the other wind canceling their self inductance.


"Suppose you want to make an air-core transformer. Which of the four types of coil would be the best choice for this? One more time, the answer is the regular solenoid coil. The regular solenoid coil will meet the design goal with a more efficient coupling for power transfer, less wire used and less resistance and less unwanted self-capacitance and have a higher working frequency bandwidth."

Sorry but i don't agree about that point that regular solenoid have a more efficient coupling in power transfer , and even with less wire , resistance and self-capacitance . You should test before talk otherwise you are just talking something that someone write and you assume that true is unbreakable .

"I will just repeat to you again: I am telling you with 100% certainty that it is a major mistake to use a square wave when trying to find the self-resonant frequency of a coil. What you should be doing is trying to understand for yourself why I am saying that. Rejecting what I am telling you is the wrong course of action."

Sure i understand , that point and i did not say that is the best option or not , just tell that is possible with a square wave find the self -resonant frequency of the coil in same way.
About i go in wrong course of action ...  Will it?

"I probably just raised more questions about bifilar pancake coils and three other variations that you may never have even considered.This is to get you and your peers to start critically thinking and examining all of the issues. Chances are that I am viewing this issue more deeply than you have ever done before, and I am not even a hard-core electronics guy. Sometimes things really are carved in stone."

Now you are start acting a bit more weird  ... what peers are you referring ?  About you say that are viewing more deeply than me , for sure not , go to bench and test it is easy and after you can show us .
OHHH i forget ! You don't need you already answer that in last email your "peers" already did that no chance of that "peers" fail.

"I am challenging you and your peers to improve your wisdom"
I'm improve everyday , even with less correct information provide by other , and i do not feel like I knew everything, my learning window is still open .


"The general conclusion will be that the regular solenoid coil performs the best and offers the most inductance per unit of wire length and therefore has the least amount of resistive losses. It also has the least unwanted self-capacitance that reduces the working bandwidth of the coil"

Is your conclusion and i accepted that , but not agree .

"If you think a series bifilar coil is something special then you have to make tests and demonstrate what makes it special and why."

I don't think that coil is special , i guarantee that is real special because i already test it, otherwise why should i use in my  work ? . Should i demonstrate to whom ?
To you ?
Just put you hands at work and see by yourself , otherwise you are just throw away words like a parrot nothing more . What is the difficulty to you in test it ?  Is you that are try convince me and my "peers" about your point of view , go forward show something to us ! To me since i'm a member of this forum it will a pleasure see you make something more "palpable" then simple talk .

Have a nice day MH

I got shicked 18 months ago when I commented on Skycollection's Conradelectro P/I P/O test. Jorge determined that his six Hexafilar LED's, not connected by anything more than wireless induction between his Tesla serial bifilar pancake coils, sustained amperage but suffered a voltage drop instead while the LED's maintained their luminosity. The reverse of conventional grid usage where they feed amperage into the system, and voltage remains constant. Suppose we have to feed lights in parallel down a 10 miles long wire. Ohms law of inverse resistance to voltage points to the advantage of stepping voltage up to feed the farthest lights, rather then generating amperage.

With this bifilar pancake coil i can charge the 12 v battery without magnet rotor, can you describe this experiment...?

Nice experiment, and a nice stack of pancake coils!

I've been wondering about charging a battery with the dielectric resonant voltage. Thanks for showing that it works.

Have you noticed a difference, in how the coil is connected? I noticed, north is stronger. Why do you not use 2 diodes, to create a plus and minus from the resonant sine wave?

really cool to hear it buzzing with the magnet on top. I hear my coils buzzing sometimes, when I load them unbalanced.

Skycollection is sending power with a longitudinal magnet wave wirelessly between his bifilar pancake coils at self resonating frequency. This conduit for power acts like a super conductor.
