am I doing the frequency tests correctly?

Hi Tropes,

I hope all's well with you. I had heard of this theory back in the early 80's and have tried it out myself during my pulse motor experimentation era.
I don't recall who it was associated with, I just remember reading it somewhere.
Alas, what works in theory often has a strange way of  working but doing also something completely unexpected in reality. When used as a generator/motor coil in front of a single magnet pole, it yielded extremely poor results in my own experiments. The duel cores inductances are actually self cancelling. The reason will take a page of description and diagrams to explain. Whew ! more work!  But I must say that it is worth an explanation. I will try to come back to this subject after I've finished covering a little more ground on pulse motor design. I've still got a lot to say in that area - probably too much! (LOL)

P.S. - I can't overstate the positive aspects of the "Alloy" nature of the sheaths. When comparing like for like with ordinary soft iron which I did in later experiments, it became very obvious that the huge gain in voltage and current availability was due to the nature of the core material. (The shape still matters - see updates on my site) But dont stress over this, because I am sure that it is not some Exotic once only fluke alloy, but is widely available and at a cheap enough price even at retail, that you can save yourself the time and trouble of repeating all the experiments with soft iron tubing and just go out and buy them pre-made. Still, experimenting is a pathway to understanding!

Hi Hoptoad
The cancer cells have been removed so all is getting better with me thanks. I'm sure the alloy makes a difference but the reason I cannot use the complete outer sheath is I am trying to shorten the coil on my new Sotropa Motor so there is a less distance and greater attraction by the opposing pistons. I would need a sheath 3/8" Diameter by 7/8" length. Both ends of the coil are used to attract and repel the magnetic pistons. However, I will check out the wall anchors at the hardware stores.
I have upgraded http://www.theowlnest.com/circuit.html so anyone wishing to have a circuit posted should upload a jpeg or gif to this forum and I will post it on this page.
Anyone new here should read http://www.totallyamped.net/adams/index.html

Good work tropes and toad.

@ tropes. These bolts are sometimes reffered to as dynabolts I believe. The slots in them are designed to spread apart when a bolt/nut is driven into the center. Excellent for fixing say the frame of a house/wall to concrete/brick. They do come in a multitude of sizes over here, but if your unable to find any I'd imagine a similar material could suffice? You could make cuts similar to the bolts in another piece of tubing and obtain similar results I think.

@ Toad. How well does a Bedini style core stack up against these? I'd imagine a bunch of welding rods or tie wire would perform similarly to a laminated core? Fascinating reading by the way, you should have been a teacher!

Go and check out page 5 if you havent already people. Three thumbs up (well two thumbs and a toe/toad) ! lol

Hi Ren, I'm glad I'm getting my experience though on this subject. I really want some of you to try what shall be revealed in good time!
I don't want what I am saying to remain in the realm of just my own observations and experiments. Replication would be great. I'm sorry its taking me a while to get to "the anomoly" I keep hinting about.

But writing this stuff up in a way which is readable and understandable to anyone who has only a very minor understanding of electronics is actually quite a challenge. Please be patient as I let things unfold. Robert Adams was onto something very valuable. But he, and many others after him, have jumped to the wrong conclusions, because I think, it is easy to do so. That old expression of "can't see the forest for the trees" is often very apt.

Bedini motors are just another form of pulse controlled motor running in an open magnetic configuration. As such the principles I have outlined for coil cores applies as much to a "Bedini" as it does to an "Adams". The only real difference with bedini motors is that that usually use a trigger coil instead of external semi-conductor sensors to do the switching. As such, they provide a more rounded semi-sinusoidal switching pulse than a square one.

Yes, " a bunch of welding rods or tie wire would perform similarly to a laminated core?"
But a hollow core made from the same material as those welding rods would be better. In fact, place a number of welding rods in between two hollow plastic cylinders to form a ring which looks like a hollow tube. You will get as much, if not more, out of the coil as you would if the whole inner circle was full of rods as well. But you will have significantly less drag.

P.S
I've just finished  and updated page 5 - will move onto bi-filar coils and working models next.

Please check out my comment on your youtube video Paul. I'm sorry for giving out the wrong info. There is a great tutorial for reading RPM from an oscilloscope and I will need to find it. If you have a Hz measurement on your multimeter, then we won't need it. Sorry for the  inaccurate information.
