ANOTHER MOTOR THAT DIDN'T, BUT PLEASE LOOK. IT HAS MERIT!!

[BEP]

With this base idea the object isn't to shield but redirect.

Put the gears on the end of like drums, side by side. Place the magnets in a spiral form around the drums (like mirrored barber poles.)
Continue the design so all magnets are in attraction mode 2/3rds of the time of rotation within dual, graduated distance shells and repel mode, magnet to magnet, the rest of the time.

The point is to create larger number of mag-mag repelling than two magnets attracting to the metal separator they are being forced to leave behind.


Chew on that for awhile 

BTW: Anything under 4 inches in diameter is nothing but a headache.

It is an interesting idea, maybe you could have more success redirecting the magnetic flux ("shielding") if you actually use weaker magnets.
Another thing that I have noticed with attempting PMM builders is that they are starting to look at using asymmetry, so far I haven't seen anyone use asymmetry in the form of magnetic field strength asymmetry...Just a thought...

Thanks everyone for the comments.You gave me more ideas that will keep me from going fishing today. I now see that this idea is nothing new, but my design is different in only a couple of ways.
This website at The Flying Dutchman shows just how close my design is to a previous one.

My idea is using a small gear set starting at 1.500" Dia. My theory was since magnets do most of the work so close (per this table)

My next attempt will be to use a small magnet (I need to order a .062 X .750) and thin steel shim stock bent into a "V".
Once again, use your imagination here, I know enough about AutoCAD to be dangerous. That's all.

Hi John,

Would like to refer to a patent I mentioned already to you but sorry for forgetting an important part of it: it uses an pulsed electromagnet to help the rotors pass over the dead center....

Go to this free patent server link http://www.pat2pdf.org/ and enter this US patent number: RE29165
It is the reissue of an earlier US patent: 3895245

I think the description sounds correct.  The drawing shows the apex of the V shield does not reach the geometrical center but ends earlier than that,  I think it would be worth extending it further than the center line.  It is possible it was a  deliberate patent "trick" drawing like that, so that a pulling pulsed electromagnet could be included to avoid the 'perpetum mobile' look or claim...?

Good luck,
Gyula

I CANNOT figure out why NOBODY looks at this Magnet Motor.

This one WORKS!!!
