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

I think the JLN CEMF test is just a common mistake!
He is not taking into account the winding around the toroid is the same as a loop of wire.
With two passes it's like two wire loops. It all makes sense, when your above the spinning magnet centers, the field curves up through the cores open center and induces current into the loops of wire (single direction windings).
When you move below center the same thing but in the opposite direction.
If only two layers of windings were placed around the cores, one layer progressing clockwise and the second layer progressing counterclockwise, the effect would cancel itself and nothing would show either above or below the center position!

Any thoughts on this?

For the demo rig, I will tell you... JLN is correct!  Please go to 4:06 for Part 2 and hit pause.  the unit on the left is Orbo...why?  NO CEMF.  Why?  Because on this machine you have the toroid EXACTLY lined up on the Neutral line between the North and South facing magnets.

How exactly would you get any attractive force from a torroid located on the neutral line? Aren't we talking about 100% cancellation?

Cancellation only of the CEMF, NOT of the attraction...LOL

Hehehe ...

Who can tell me the difference between the "orbo motor" and the "pulse motor"??  Anyone?  Bueller?   LOL

Now...Look at the "pulse motor" on the right...what do you see?  You see the toroid Higher ABOVE the neutral line, and thus inducing CMF into the machine. 

Lastly, I am starting to doubt that the toroids are 1".  They are looking more like 3/4".  Can someone help me deduce the correct size please?  Thank you!!

Hi Bruce,
I think they just used only toroidal coils without ferrite cores in them
and did not put them inverted in series.

Then the Counter EMF adds up and does not cancel.

Also he said, "we have to compensate for the higher current in the NON-Orbo",
so you see, that they did not use ferrite cores, so the current rises
much faster in the same sized coils, thus needing much more
current when they are energized energized...

dtorus:here's a question from our audience:
"ask him why the Kinetika Orbo has not been shown again. If he was not lying about it being fully functional and OU before the bearing failure, why are they now displaying something that requires explanation and an oscilloscope to 'prove' OU?"

Sean what do you have to say to S. from Wisconsin?

Steorn:
Because its a horror to build and we no longer work with the company that made them for us.

Also, from Steorn :
There is no back EMF in the PM systems - but it works on the same principle of change of permiability during the interaction.
