I did away with the repulsion element of the old design and made a new entity that is all attraction and super simple in it's operation. It uses a version of our Pseudo Solid technology as well as our Magnetic Force Cancellation technology and Multi-fieldpath technology that allows it to create extremely high torque. As many as 16 or more NIB rotor magnets can be utilized on the rotor.

have you had the chance to build it and test it yet?  looking forward to the result. 
thank you for posting.

Outer flat ring removed, drawing attached
« Reply #6 on: March 28, 2009, 02:46:47 AM »
See drawing and simulations attached. I was hoping that the attraction force of the rotor and fixed stator magnets to the rings would be the same when they were seperated and when they were lined up with each other, but to my suprise the pull is greater, almost double is some simulations when the rotor and stator magnets are lined up. That is when the rings snap inward which is exactly what I need for overunity ultra high torque operation. It has finally all come together.
Thanks,

Outer flat ring elimated from design
« Reply #7 on: March 28, 2009, 02:49:51 AM »
I have removed the outer flat ring from the design. It help the magnets have more attraction pulling the side rings in than when the rings move back out.
Thanks,
Butch

Special note on side rings
« Reply #8 on: March 28, 2009, 02:56:56 AM »
The side rings have to be a ferromagnetic material that is a nonelectrical conductor so as to eliminate eddy current drag.
Thanks,

Operational sequence of this design listed below
« Reply #9 on: March 28, 2009, 03:28:18 AM »
1. Rings open, rotor magnets 20 degrees from fixed stator magnets. Super strong attraction between fixed NIB stator magnets and NIB rotor magnets.
2. Rotor magnets are pulled to stator magnets and line up with them, but two degrees before lining up side rings snap in leaving a .010" air gap between side ring and magnets. Ring movement inward is complete as rotor magnets line up directly under fixed stator magnets.
3. Rotor magnets are now free to rotate around to start sequence again. The side rings snap open when rotor magnets are 20 degrees from fixed stator magnets.
4. Side rings have force cancellation system incorporated so there is no resistance to inward or outward movement due to magnetic forces.
5. See LaFonte Group Youtube site > http://www.youtube.com/user/LaFonteGroup  < for information on this cancellation system and an animation of the machine in operation.
6. Note: 16 or more rotor magnets with 16 or more stator magnets can be incorporated in this design for ultra high torque.
Thanks,
Butch LaFonte

Does such a ferro material exist?

Every ceramic magnet is such a ferro material. Also most toroidal coils cores use this material.

This is the largest and cheapest ferrite ring magnet I could find on ebay.

http://cgi.ebay.com/Large-Powerful-Ring-Ceramic-Magnet-2640g-94oz-8_W0QQitemZ330318441532QQcmdZViewItemQQptZLH_DefaultDomain_0?hash=item330318441532

It shouldn't make a big difference whether they are magnetized or not because all that has to be done is balance it with the correct amount of magnets to open them effortlessly. Out of experience I know that ferrite magnets will attract neo magnets regardless of pole side as the neo can flip the polarity in the ferrite magnet. But if this is really a concern one could just put them in a high temperature over and push them past their Currie point to demagnetize them.
