STEORN DEMO LIVE & STREAM in Dublin, December 15th, 10 AM

@woopy,

Is it possible to dump the current and voltage data seen on the screen of your DSO (corresponding, say, to one full turn of the rotor) into an Excel spreadsheet and upload it here? Can you also tell us what the Ohmic resistance is of the coils where you've measured the said current and voltage?

hi Omnibus

Thanks for your interest

I am now on the very basic testing of these "ORBO" concept. And I am very impressed by the Ossie Callanan idea of one coil  (so easy to build) distributing all the effect through all his circonferencie. and so we can add a lot of attracting magnet on one single coil. Very intersting  !!

I have made some basic testing with the multi toroid ALA steorn (my basic ser up works quite fine ) but i think there is a lot of people here who are far more advanced than i am in this direction . I will of course follow tjhe  progress attentively.

But for my 2 cents in this technologies i will try to go deeper in  the MONOCOIL-OSSIE idea. I hope this will not disturb this thread , and i think it  is a lot to learn on this idea . Of course if it is needed  i will ask Ossie Callanan if he wants to open dedicated thread to develop his idea separately.

To answer a part of your demand  i have made 3 monocoil

1      is 2 Ohm  about 20 meters of 0.4 mm copper on a soft core (see picture)       good result at 7.2 volts it takes out 0.8 amps to spin the rotor quite fast ( sorry i did not test the rpm and torque) but encouraging first try.

2      is also 2 ohm and about 20  meters  of 0.4 mm copper the core was hard steel with hole all along   no success  the motor did not spin at all. The cogging was very strong.

3      is 6.8 ohm   and x meter of 0.3 mm copper (i dont know because i have made a machine ALA Ossie to wound it and i simply made the winding "at the nose")  the scope shot  you mentionned is with this winding.

So i am not ready to make deep invastigations in one or another config , i have first to test basic fonctional improvement on what Ossie said already   that is the EDDY currents of the monocoil princip

so i enclose here to all the contributors of this forum some idea of how we could build  these core and please feel free to give your correction and critics

It would no doubt work much better if Ossie were to wind his special coil on a steel SLINKY toy for the core!
The lamination's should nearly remove all the eddy currents.

Hey guys - great work with this thread.  I think many of you don't realize that there are many of us following this, even though we don't contribute to it on a day to day basis for various reasons.  Mine being that I'm unable to get the right cores and not very good with my hands.  This type of replication takes more skill than using duct tape and WD40.

One idea to throw into the air is this:
I was wondering what would happen if you were to wind a toroid in the way you've been doing to cancel out the magnetic attraction of the rotor, but at the same time wind another coil AROUND the whole toroid which could be used to generate power as the field gets magnetized during rotor attraction?  Drawing power from this may even increase the attraction (or not)... and this energy should be free since it's not affecting the toroid at all. 
You could either have a separate pulse for that or try and pulse it at the same time.  Or maybe just a diode bridge connected to a dc battery, I have not thought it through enough.  Incidentally - this may be used for a solid state orbo as well - it needs experimentation.
Until I do get my cores and some time to play around I hope this could be tested by someone on this thread.
Thanks

@ akashh,

Some time ago in this thread, Ossie used the same concept already.  However he did not use it for generation purposes per say, he used it for a trigger coil on his transistors.  But, Ossie has been moving a mile a minute with his work, and I'm not sure he ever checked to see how much could be generated that way if it wasn't only used for trigger purposes.

Hi all

Nice sunday and i got the idea to replicate the Ossie fence wire coil but on an other configuration. See attached pictures they are self explanatory.

The voltage is 7.2 volts
the coil is 2.4 Ohms wrapped one layer opf 0.3 mm copper
the diameter of the core  about 3mm fence wire

the magnets are 5mm cube neomagnet 50

result is much less Eddy currents
much less cogging

the motor spin till 2120 rpm ,  my best result until now

but the current is about 0.8-0.9 A

So my question.  Would it be better to wound the core with 1 layer thinner copper, or wound a second layer backwards with the same 0.3 mm copper

Thanks

Laurent
