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.

Thanks,

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

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,

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
The side rings have to be a ferromagnetic material that is a nonelectrical conductor so as to eliminate eddy current drag.
Thanks,
Butch
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,

Does such a ferro material exist?
Cheers

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.

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.
See attached drawing.
Also see this video link of magnet force test.

Butch, any idea in mind on how to build the linear setup? The only suggestion I have is to use some linear bearings and coils for fast movement of the two magnetic rings.
Broli,
Yes, I have a super, super, linear design for proof of concept. I will make drawing and post in a few hours.
Thanks,
Butch
Note: The two side plates can not be connected at the bottom with any ferromagnetic material.
Lowes Hardware should have everything you need for this except magnets. They might even have those.
Also, before sliding up side rails make sure rolling magnet is as close to being centered between the two side rails as possible.
If possible the rolling magnet should never touch the side rails because it will cause unnecessary drag during the repositioning to start position phase.
Thanks,
Butch LaFonte

have you solved this problem yet? the problem about the pull force being greater when the magnets are not lined up.

It's not really a problem. When they line up and the plates go in this stores a certain amount of energy in the repulsing magnets on the outside. When the rotor magnet then moves away this repulsing force will be double of the force that the stator and rotor magnets are pulling the plates with. So it wants to spontaneously open the plates again the moment the stator and rotor magnets are not aligned. So it's a good thing. A mechanical switch has to be installed though so that it doesn't open too soon on its own.

Cairun,
As you can see in my video on youtube, the pull force when the magnets are lined up is the same or greater than when they are seperated.
Also I stopped using repulsion, the magnets are in attraction now when they line up.
Thanks,
Butch LaFonte

interesting. i thought it would be exactly the opposite, that the pull force would be greater when the mangets are separated. perhaps your concept is, after all, different from mine. good luck!

Sorry, but I don't recall your concept, did you post it here?

no, i have not posted my concept. i do not want to give false hope.
if my concept works, then the world will know; on the other hand if it does not work, then, it is not worth the effort to post it.
for now, i am more interested in the result of your work. i do believe your concept will work, given enough time and effort. so, i wish you the best of luck.

thank you for answering my question. it is a good demonstration. i guess i was thinking of something else.
This link will only have information on one motor basic operating principle only.
