4 PISTON MOTOR THAT JUST MIGHT WORK. YOUR THOUGHTS PLEASE...

Magnet drive....

I did a quick sketch of the only possible way a mechanical advantage could be gained using shields.

Thanks for that drawing. I need some more info to be able to use it, I'm afraid.
The green objects are sliders I suppose?
Is the shield you've drawn completely replacing the moon shaped shield? In the original drawing?
Thanks.

The shield is the orange wedge shaped area and they are about 3/16 inch thick.
There are actually two of them and they rotate with the center gear and pass closely to the magnets on both the near and far side of the magnets.

This shield will draw the field and conduct it to the other end of the magnets so there will be less force as they approach the other repelling magnet. This configuration is the only one that showed no additional drag removing the shield as the gain from moving onto the magnets.
There will be some additional pull if the repelling magnets are moved very close together but then there is also some extra pull as the shield moves to the next magnet because it is further out on the rotating diameter.

So you would drop the half moon shield all togeather?
On your drawing, The stator is stationary isn't it?
Did you assemble something like this? I can see your theory, but it looks like a real trick to design around a stationary stator.

My magnets and 3.5 inch gears arrived today. Initial thought, I should have gotten 2.00 gears, the magnets are very powerfull, but they are not going to push much after the first 1.5 inches.

The gears are not a problem, you can always put the cam location anywhere on the gear to get whatever stroke you need.
You can try the half moon in the same setup to satisfy your own curiosity. All I'm saying is while testing different shield concepts, the only one that showed any hope was the side shields because they indicated nearly the same pull with the magnets separated as when pushed close together.

The center magnets do not rotate, they are always inline with the piston magnets.

I usually only build what is needed to test the concept and believe you could test this concept using only one piston and one center magnet with two gears and two other stationary magnets at the position of the next piston just to assist the shield.
If you get a good indication of operation at this point then proceed on.
