Looking for ... I got it!

Hello Grumpy
I think we are talking about the same thing, have the same opinions, But have different meanings for the terminology. When you say keeper, I see a piece of metal short circuiting the flux of a PM and is locked in the field. A shield must shield and not redirect the flux. In your last post I realized we are saying exactly the same thing, and I agree with what you have said completely, Your example of a foot long magnet and "shield" is mind boggling, I didn't get it for a minute then Wham, I can be a little slow at times. This is brilliant, I was looking at the LEMA as the best solution but I think you have a better one. It's just bizarre that the answers are always right on the end of your nose but you can't see them. So let me get this straight- you have a foot long magnet screwed to a table, above it (a few mm)is a piece of flat iron let's say 8" long, this flat iron has wheels keeping it 2mm above the magnet and can roll back and forth. So the flat iron never leaves the magnetic field and can move freely(which I knew)except if it moves fast eddy currents slow it down , so you don't move it fast. Above the flat iron is a rotor with iron cores spaced around the circumference, or better two rotors, one on each end.
The flat iron shields the magnetic field from the one rotor, and exposes the other rotor, the shield moving back and forth then alternates the magnetic field on the rotors. This is just too simple-which is why I never had a clue, it needs some refining but this is definately something I have to build!
Have you built this Grumpy? can you tell me anything else? this rocks

This is what I was thought you meant, it's crude but get's to the point.

One thing I am wondering about is that when the flap is open, it offsets the balance of the rotor.  Even though the weight would be the same, the distance from the axle would be greater, putting more leverage on on side.  Even though it would be a little more difficult to build, perhaps a "slider" may be incoporated to keep the axis a closer to "balanced." 

yeah i think you are right, the arms are open for the magnets but also since the arms are extended/open there is more weight on that side of the wheel. the forces cancels each other out

anyways what do you think of this wheel http://www.overunity.com/index.php/topic,894.0.html
i was also thinking of using this wheel in a pure gravitational way where you would have maybe like 10 wheels (same type of wheel, one next to each other in a loop) in a loop and would start one of the wheels manualy, it would have a domino effect continuously.

I meant like this (see image), but you are close.  Use opposing magnets on the rotor - iron will always attract.  If you put the magnets in cups or somehow wrap steel around them, the exposed pole will be up to four times stronger. Check this link out:

The motor can be created axially or radially, but radially handles the deflection better when the fields interact.  Axial orientation lets you use both sides of the rotor, but it has to be stiff.

Also, no eddy currents if shield does not leave the field (i.e. cross the field lines).  You nailed that part.

Hello grumpy
I have built that exact same motor and the problem I had was when the shield is moved to the side- the farther it moves from center of field the greater the force required, you can't get this energy back again because by that time the rotor magnet has moved from register, the force to move shield away =3, force pulling it back to register =1, equalling -2. I don't know I have tried all this and could not come out ahead. But---But if the lower magnet is larger and the shield does not get even close to the edge of the magnet-then maybe the shield can have neutral forces. That is why the motor I had shown has a large magnet on the bottom and the shield is smaller. As well, I have found it very difficult to balance a shield between two magnets in repulsion-the repulsion force must match the attraction of both magnets to the shield exactly- and when the shield moves everything changes- It looks easy, but definately not in reality. I think Im going to try the motor I had posted I have not tried that configuration yet, I'll keep you posted.
