Self running coil?

[gotoluc]

Hi all, I did some tests based on some comments in this thread to satisfy my own curiousity.  Dont know if its useful or not, but here are the results.

Core: Metglas 2714A 2510P4AF Flat Loop  25mmx19mmx10mm flat loop

Magnet wire - 22 guage

BK 878A LCR Meter

4 turn wire - 12"

2 turn wire - 6"

1 turn wire - 3"

Data is at: http://spreadsheets.google.com/pub?key=twYJTFuWUrRAMMzos--b_LQ&output=html

I dont know if there's anything useful in there yet - I was just recording data.  One thing I saw was the discrepency between the 2 CCW + 2CCW series and the single 4 CW - I wound those setups twice to verify that it was different.

Hi void109,

thanks for doing these tests. I would guess that the 2CCW 2CCW Series 1094uH result would be the way my coil is done.

It would be of great service if you can try the following idea.

Someone asked me, if 2 coil section wound and connected the correct way (in series) will double the inductance, will 4 or more coil section quadruple or more the inductance.

Can you do a test to verify this, as it would be of great help to all replicators.

I'm not sure how the 4 sections would be connected to get highest value, so you may have to try many combination's to figure it out.

Please let us know what you come up with.

Thanks again for sharing all this great data with us.

This is what I have been doing ever since I started this topic Gyula.

No battery is connected and the cap bank charges up.

Sorry Luc, I have lost in the circuit and measurement details so much that I forgot about the overall history...

No problem Gyula

I do appreciate all your test suggestions as I would hate to overlook something obvious.

This makes me feel better that someone with so much more EE knowledge than me cannot see something that has been overlooked.

I'll keep developing it and posting the results.

Thanks again for your assistance

Hey Mags,

I am still going to try...but, I have now reduced my input power from 2 amps using one toroid, to having 4 toroids in series and a 100 ohm resistor on the battery lead.  Amps are reduced to .070...  

The idea, I am thinking, will be to wire in series as many toroids as possible, all the same cores, and windings.  Wrap with just enough windings to oscillate the magnet.  The MORE toroids in series, the LESS power used...why?  Because the toroid DOES NOT SEE THE LOAD, because the power is being generated by oscillating a magnetic field.  Yes, more amps make it to oscillate better, but having the proper core, with powerful magnet inside, should more than make up for it.  I will add up my output power tomorow and see where I stand.  But, hehehe, I simply need to keep adding toroids and remove the 100 Ohm resistor.

Cheers,

Bruce

The above is a quote from Bruce in another thread.  He says, having more toroids in series, lowers the input power.  If we connect two toroids in series, and used both ends of the magnet between each toroid in a figure 8 or an overlapping figure 8 configuration, then we may have an increase in performance, as compared to a single toroid where only one end of the magnet is being used.  The unused end of the magnet with a single toroid can bias another toroid at no cost, let's use it.

I'm just trying to throw out ideas to improve upon what Luc has already done.  It's not changing his system, other than utilizing what isn't currently being used.  Let's exploit the system to it's fullest potential possible.

Hi GB,

I agree with you!... the dual toroid idea sounds good.

Please note that adding toriod's in series is also a way of increasing inductance. I'm starting to think that maybe a high enough inductance coil on a ferrite core toroid at resonance may return some energy even without adding magnets.

Many things to test
