Romero's experiments and OU principles
« on: June 11, 2011, 02:26:08 AM »
This thread is focused on Romero's understandings and experiments that led to OU.

This will be a very strictly moderated thread with the goal of documenting the principles and experiments necessary to achieve OU.

This thread is designed to be a concise and focused. Any deviations from the objectives will be simply deleted.

Fausto.

I have just answered on youtube and might be relevant  to all members here interested in this effect.

The ideea is that more  load to increase the speed and that can be obtained.
More load brings the system close to shorting the coil.
This works at certains speeds and again in a cycle.
Example:
if it works when we have around 500rpm it migh work again at 1000 and again at 1500...
in reality is not calculated like that, this is just an example.
I am working to get the right formula.
if you turn a rotor to speed and look at it at one point we will see like it turns in reverse. that is the important moment we need to consider.

Regarding shorting the coil:
why not to keep the coil shorted all the time and release it only at the right moment.

Example:
a plastic pipe with water flowing...
we cover the end and it creates pressure inside then if we release it from time to time we get a nice strong jet.

Well that Zener idea mixed in with what Bruce was saying could do that.  USe the zener to keep the coil shorted until it hits its breakdown voltage and it releases the pulse.  This was something I mentioned to my friend the other day.  Keep coming up with ideas to test while im finishing the mechanicals.

One of those simple ideas that prompt a,'now why didn't I think of that' response. Thanks Romero, good to see you posting here, we appreciate it!

The coil in the vid ... has two windings?

Rgds, Ron

edit: understood... but in this case I felt the context was lost and people needed to know, "what idea" ... you may delete this explanation after you have seen it, danke schon

Hi RomeroUK,
the output-coil or generator coil in the video comes from a microwave oven fan and you rewound it?
Now it has two windings/coils on the old core?
One is clockwise and the other anti-clockwise?
So one would think the two produced signals add up to Zero or "cancel each other"!
But the arrangement actually produces power bursts, when the passing magnets FLIP the core's magnetization, producing signals in two coils - wound on a single core.
The power-output reaches maximum levels at certain rotor speeds:
At these ideal rotor speeds the FLIPPING frequency created by the passing magnets is in resonance with the delay that occurs between the clockwise and anti-clockwise windings which are connected in series.
It is the delay between the two signals, which is due to the length of the wound wire, that prevents cancellation ? (Struggling for words)?

Hi,

the coil is from a microwave fan and I did rewound it
I cannot confirm or deny the other questions but I can tell you that I had to rewound that coil many times to get it right and used it in many experiments to compare it with other normal cores.
that particular coil is an expensive one, not because of what I did with it but because it uses Mumetal core I made from mumetal sheets. probably it is arround £200
below is a picture with coils and cores I use for the testing before going to start another project
I am working now for more coils direct wound on the core.
konehead posted a very important tip... to have them wound direct on the core and we get much better results - he was right, tested and yes, I can confirm that makes a big difference
This is the reason I am using selfbonding wire now.
Thank you konehead!

Hi Romero,

Of the different cores you have used, which give you the best results?

Thanks!

Nothing better than mumetal but irondust ones are good enough for NSNS orientation and not too good for  a rotor with all poles in one direction.

For solid state DC pulsing, MuMetal cannot be replaced with anything, the difference is huge. I wonder how it works in a standard Kromrey setup.
The big square coil in the picture posted before has a big solid mumetal core inside. I can take the core out and replace it with 2 other cores same dimension I have, ferrite and irondust, this way I can compare them and do more testing.
I am not talking about homemade irondust, I bought them all, proper stuff.
Home made I used in some Microwave fan coils and in some Bedini projects.
I also used irondust to make a big ring with holes around, for another type of generator, replication of a patent from the internet...
I can say that irondust ones are better than any ferrite tested so far, now it depends what is going to be used for.
Have a look at the prices of mumetal here in UK. http://www.goodfellow.com/catalogue/GFCAT4.php?ewd_token=6NKOmHMvvby35MC7vIxKR83q3DRLzK&n=bV6txUGvOJIhGeYeKEfqFtZ8hlUwiW

I bought from them few times but still China is  better for the price but must wait a lot.
Clanzer said he bought from them too.
I cannot even tell you how much I paid for the big mumetal core..., 10cm long /2.5cm/4cm. I could have stayed a week in a good and nice hotel with all 'services' included

All the best,
Romero

Hi Romero

In your latest video you mentioned  of hard disk magnets  which im using right now
With NS  top and SN   bottom   configuration  what trigger and driver circuit that can be adapted to this  ?????
Also   im trying to use microwave oven   berrilium oxide magnets instead of neodyne
but will try the shorting of coils  again    any advise  on the circuit  driver and trigger
My objective is to have a ??? kw   gen

Hi Romero  additional question

Besides the cores
Winding in Neogen  bifilar   or just bifilar  by Konehead in RV   mode
Which is more  efficient  with N S configuration?????

Cores depend on the frequency you wish to operate. Ferrite is good from hundreds of Khz to several Mhz so it not much use at lower frequencies as the magnetic retention on domain flips is too short.

Iron Dust is best for lots of  Khz  thus is use in switch mode PSU's typically running from 25khz to 90Khz after that the iron dust actually can not respond fast enough for domain flipping. A small 1" core can handle as much as 1000 watts without saturating.

Standard transformer especially large ones are excellent for low frequency work. A 1000KVA utility transformer is >98% efficient.  You will see excellent results working with large transformers over 500VA and will work very nice from 20Hz to 450 Hz is about the upper range.  Use variable pulse width, frequency and amplitude drivers to make KVARS's

You will really struggle working with tiny little cores solid state systems when the switching events have to take place at very HF creates all kinds of problems and tuning becomes a real bitch.

For some real data:
http://www.micrometals.com/materials_index.html
Iron powder suitable from several KHz up to 1 Ghz.

You're probably mixing up with permeability differences.

Winding in Tesla-Neogen bifilar is really the best for generator and for the driver coils but not easy to make the coils like that. I have made 2 coils just to test  them but I spent almost 4 hours to do them and wasted a lot of selfbonding wire.
I am in the process of making many coils directly wound on the irondust core. I will post pictures with them next week. In NN config I find iron dust better than ferrite but in NS config the difference is not that high but still irondust is better.
Today I have just finished milling a rotor made from nylon66 and I am preparing another Acrylic rotor for a different config.
No more work today!

No im generalising without going into exotic iron mix like carbonyl iron with ceramics can run to a Ghz. But in practical terms anything over a couple of megs  is already heading towards air cores. As Ismael uses Tesla bifilar Air-Cores for his MEG.

Wiki

"Iron Powdered cores made of hydrogen reduced iron have higher permeability but lower Q. They are used mostly for electromagnetic interference filters and low-frequency chokes, mainly in switched-mode power supplies.
[edit]Ferrite
Main article: Ferrite (magnet)
Ferrite ceramics are used for high-frequency applications. The ferrite materials can be engineered with a wide range of parameters. As ceramics, they are essentially insulators, which prevents eddy currents, although losses such as hysteresis losses can still occur.

So unless you have an incredibly fast rotor its probably going to work better  with iron powder while the old AM LW MW radios used ferrite rods, slugs and cores for these frequencies and certainly not iron powder.

Mu-metal is pretty powerful stuff and as romero said VERY expensive. Don Smith used a lot of Mu-metal as well as another type which is around 10 times the cost of Mu-metal i cant think of the name right now,  Mu-metal has  permeabilities of 80,000–100,000. There is a trade off for materials there is no point making a 15 watt OU device that will take 200 years to pay for itself:)
