Hi all !
Got the ring magnet. Last year cost me 158 USD. Got the rotor2 magnets.
I read the whole thread once again. And let's now answer to this question:

Lets say thickness of shield and distance rotor2 is made to rotor 2 "feels" slight attraction to rotor1.
(this is 100% possible)
Why would rotor1 (shield) when moved 10mm left from rotor2 "Feel" strong attraction ? (in this case it won't work)
slight attraction of rotor1 to other elements can only come from thickness of shield so if shield is moved
still there is only slight attraction.
answer: it can't feel strong atraction only slight

so once again I think the only drawback of this design is repulsion mode which tends to deplete magnets fields, but if made
properly (thick magnets and spaced enough) it could run forever.

ring magnet is 200mm outer diameter and 160mm inner.
My home budget is depleted and screaming at me, so if there is someone from Croatia preferably Zagreb and want's to
build it with me properly, it will sooner be made. setup could cost 70USD and we split the cost, and share infinite glory
afterwards.

Hi Wizkycho.

Nice to see you back again. Please keep us informed about your developments.
I didn't forget your idea the whole time along...

Greetings, Andi.

Here are the stator , the shield(input) and the rotor(output) magnet pictures.The dimensions of each one is in such way that the distance betwen the rotor magnet is 5 mm from the shield and from the shield to the stator is 3 mm.So the distance from the rotor magnet and the stator is 9 mm including the thickness of the shield wich is 1mm.Now I have to figure out a way to assemble the whole setup.

Best regards,
Cristian

Hi Christian !

Stator is good. Rotor2 can do but try to find magnets that shape follows
inner arc of stator magnet and shiled.

You need to work more on shield rotor.
shield surface is too big in respect to rotor magnets.
This way big shield surface does nothing.

Shield should not connect magnet flux on both sides of rotor2 (bell shape shield is no good i think)
in between there has to be material with low permeability. plastic, aluminium.

You should be able move shiled closer and further from stator magnet
for adjustment.

You should be able to change thickness of shield for adjustment, or experiment with it.
Adjustments are needed for best output.

when adjusted properly:
spring attached to rotor 1 should spread slightly.
spring attached to rotor 2 should spread much more.
Is this the case ?

If shield is satturated to maximum it will "REPEL" !?! (bounce) from magnet to the place on magnet where is less satturated and field density is lower. You don't believe this see this very simple experiment I assure You that this is not happening cause of induced current in permeable object.
the experiment: http://www.geocities.com/wizkycho/index_files/magexp.avi

Well, this experiment shows, that "shield" moves to the edge with max flux density, not repels but attracts to it. The edge has higer flux density. It doesn't really matter is shield saturated or not, it will allways move to higher flux density zone. The process is fully identical to that where two magnets attract, think of shield as of magnet polarized in the direction of magnetic induction vector - that is what happens.

When washer is placed perpendicular not horizontal at the magnets center it stays firmly in the center or anywhere on magnet
It never just jumps to the edges of magnet...

But I abbandoned that theory anyway, cause come to think of RPMM it is not involved in its operation.
Previous pictures are enough to understand why it should work !

Do You agree that Knitel's RPMM could work ?
