It looks like romero's using saturated driving coils like I tried to explain in my previous post...


With saturated driving coil, back emf can not be produced by the magnet. In theory that's right and in real, very little back emf is produced. You can check the calculations and the explanation from the link...

Hi T-1000,

some questions regarding ED L-device.

The pic above shows (mainly) the stator of the device?
What is the active side of the stator?
Is it outer ring (area) NN-SS-NN-S...? (I would say: No).
Is it inner ring (area), the Bloch Wall? (I would say: Yes). But I am asking YOU.

And the rotor is mostly gone?
It was in inside area? And had a (one or more) radial, iron-core, high-impedance coil? Going from Bloch wall to bloch wall?
Or was the rotor outside? What design?

Thanks in advance.

Regards

The flywheel in one of many videos:

Magnetic polarity: http://www.alexpetty.com/wp-content/uploads/2011/06/flywheel-1.png

All magnets are "V" phorm, the bloch wall is inside of rotor. They are 24, phorming "VV" connections with N+N-S+S (same poles from 2 magnets forced together) combination.

The PMH is missing there. The only one place where you can see it attached to flywheel is in this photo: http://www.leedskalnin.com/Generator.jpg ( http://www.leedskalnin.com/LeedskalninImageArchive.html )
Also people are playing with it:  http://www.youtube.com/watch?v=UFcd_QCLK5w

Finished winding coils last night. (See image)
Made both single and bifilar coils.
Didn't worry about specific number of turns and merely wound them, until full, on my sewing machine.

Have ordered some ferrite cores but probably won't try them right away.
Still want to play with air cores.

And, speaking of saturated coils, have you seen the latest video from Quanta Magnetics?

That is all for now.

Hello guys

Sometimes I have crasy ideeas that i must try them.
This is one of them http://www.youtube.com/watch?v=H55vrAfmMNQ&feature=youtu.be

Very cool Marius. ;]  I see that one side pushes and one side pulls, helping to negate cogging. ;] 

Ya know, those plastic bending arms with the mags, if the rotor hits the right speed, those arms will go into resonance, and really start swinging. ;] Would be interesting what effect that would have on the rotor at and around those speeds. ;]

Very nice. ;]
