Hi All,

Please see this latest update from JLN.

http://jnaudin.free.fr/steorn/indexen.htm#patent

This US government patent shows a method that can be used to reduce CEMF in toroid coils to zero by means of an additional coil wound circularly in normal fashion around the toroid's core and then wired in series or parallel with the toroid coil such that the current flow of any induce CEMF in each coil opposes each other. As long as the number of turns of this additional coil is equal to the number of times the toroid coils windings complete a full circle around the circumference of the core then it is possible to reduce any total CEMF induced in the coils to zero.

Here is perhaps a better explanation from JLN himself.

"The patent is very interesting because it say that in a common toroidal coil each layer are equal of one coil turn along the axis of the toroid. So, a one layer of toroidal coil is equal to a flat coil of one turn and thus it can catch or produce emf outside. So, to counter this, the only thing to do is to wound a one tun coil along the main axis of the toroid so as to create a magnetic field which nullify the virtual one turn coil created by the one layer toroidal coil... This is simple be this is a very important thing to do for canceling the weak CEMF induced in the toroid... "

This once again is an amazing find by JLN.

Regards,

Ossie

So is Finemet and a lot of other cores.  Just because metglas cores are tape wound doesn't mean it's the right material.

My measurements using a Metglas core show 170% efficiency (less electrical resistance from wires & the mosfet), and that's not using the energy that could be captured back from the cores inductance, which several days ago I verified can be recaptured, thus making it far over 170% efficiency.

The only reason why you want it to be a metglas core is because you have previous designs on a magnetic switch built around the metglas core.

Incorrect. What I did in the past has nothing to do my present decisions. The reason I picked Metglas long ago and also for my "Tiny Orbo replication" is because it has the highest permeability of all non-custom cores, and they offer longitudinally annealed.


To legit researchers: I do *NOT* recommend air-cores, plastic cores (magnetic audio tape), and shorting your cores, ... LOL. Please by all means try such things if you must, but after you discover they do not work well, then lets talk.

BTW, for now I no longer have time to argue or debate with people to help them.

[PaulLowrance]

This is absolutely amazing.  After reading this, I'm sure everybody will agree with me.

Incorrect. Sorry.

[PaulLowrance]

Right now most of the replicators are investigating MetGlas, but it's very well possible that soon findings will show it's not the proper material.

And what people might that be? People interested in causing distractions?  Sorry, but I've already posted measurements on a Metglas core that is over 100% efficiency. Metglas may or may not be the best choice core, but it is one core choice, and in fact it is the only core that's shown over 100% efficiency so far.

Like I've said for years, no offense Stefan, but this forum would be the LAST forum in the world I would post the Smoking Gun, a self-runner, for obvious reasons. Anyone who does not know the reasons, please contact me in private.

GB in my opinion you should hold your horses a bit I mean first some ideas have to be checked before you can say they are worth nothing ;] And I totally agree with Paul - Metglas MAGAMP cores are the best to try first. Finemet cores have too high saturation points. MAGAMPs have only 0.57 Bsat - it means only few coil turns are needed and this means low resistance and this means low heat loss and of course this means low current needed. Also MAGAMPS have very high differences between high and low permeability points - this means huge energy for free to be recaptured. Cores made of old tapes ? Oh please ;]
But what is important - many core materials are ok to be used for ORBO. But Metglass MAGAMPs are just simplest to use. Just as an example - if you use FINEMET you would have to build a much bigger ORBO - use bigger/ stronger magnets, use more powerfull batery and etc. Why to go that way if you can do it simpler ;]
Remember that what we're about to do at the moment, is to build a replication. Simple working unit. Not the "best" one. Just working.

One more thing. I've not seen a single one replication using an original ORBO's toroid/magnets setup so far. I mean the toroids set up vertically, with the toroid's hole facing two magnets. I think it should be better than JLN's setup (I've written earlier why exactly).
