I could be wrong but I have'nt found anything yet that will block magnetic attraction.........is there such a process??....shylo

You are right about this. There is no such thing which will block magnetism. But guiding the magnetism so it doesn't influence on other objects near by, is possible. That is what the magnetic shielding are suppose to do.

I have a feeling of the outcome of this design, but what I do know for sure is when energy are required to flip a magnet from attraction to repel (180 degrees flip), this energy corresponds to the energy which is provided by the rest of the system - so they cancels out to nothing. The shield in my simulations, as the picture above shows, is that the flipping magnets can do its trick without need of energy input (Which would be required due to possible counterforce from another magnetic field).

We also know it requires energy to pass a sticky spot, but if the magnetic field never pass the sticky spot, only the mass in the magnets, I have a strange feeling it will work.

If we isolate the shield together with the rotor magnets, the magnets will attract the shield in both ends even if the polarity are swapped during the operation, and cancel out the force needed to go completely through the shield. If we now put back the stator magnets, there will be a general attraction between rotormagnets and statormagnets on one side, and a general repelling force between them on the other side. Those forces will still be present no matter if the shield are present or not. The difference is that the shield will assist the polarity swap, by removing the magnetic force that prevents the magnets to flip 180 degrees. That is the only reason why I believe there will be excess torque at any time to run the motor.

Friction are energyloss which is possible to engineer more efficiently without violate the laws of physics. Creating energy out of nothing is quite much worse

Experiments will eventually show the outcome, so it will be nice to test this in practice.

Hi...
There will be few small problems.... Magnetic field generated by small magnets inside the shielding...Changing poles inside a metal tube will affect the magnets entering the shielding... First small problem... Second...Changing poles on small magnets put new problem regarding the interaction between small magnets poles inside the shield during rotation...
What is the speed around axis and speed of the system ?...so you can calculate the minimal torque to rotate the magnets inside the shielding, knowing that the magnetic field will propagate also inside the shield (the small magnets are there, so they do have own magnetic field witch will propagate inside the shield).
This is only at first look...I did had this idea last year...little different, but almost the same. Without shielding. Try with outside magnets little oval shape in the middle, not round.... (so you have bigger distance regarding the small magnets during rotation...and you dont need the shielding anymore...where as I see it, will generate problems. It will work...mine did ...But not so pleased about..Took 1 month to build and 5 min. to destroy... Too many mechanical details and joints.

Hi Low,

I will tell you a small trick...try make the outside magnets (the 2 big magnets) longer..so distance at the end of them is not bigger than 10 cm...in that point you will have almost double the power, because you will have repulsion with one magnet and attraction with other. And then, I think you can get the shielding out...as long you are turning 1 magnet at a time, there will be more than 3 - 4 pushing at maximum power if the outside magnets are long enough. This is how I did...In my model I put round small magnets with holes (like small tubes) on axel and in the center with a spiral axis they was turning...without shielding. You can also try to made 3 rows of magnets, so you will have more magnets working to turn 1 or 2 magnets at a time...and anyway, turning a magnet around his own axis, if is not so big, does not use much power. I am sure it will work.

Aaa...and you will have one more chalange 
How you plan to turn the magnets ? How are you planning to hold the part that will turn the magnets ? If you already have the solution, is good...if not... I will tell you after you boil a little 

Good luck Vidar!  I really enjoy your ideas, they are some of the most unique and well-thought of ideas I've seen.  It's also good you have an excellent grasp of the physics and can see if things will work or not.  Interesting idea!

I have done some tests with one single magnet which I guided inbetween two other magnets. I split the experiments in two sections. On in attraction mode and one in repelling mode.

First experiment went like this:
The "rotormagnet" feels a pull towards the statormagnet when it is outside, feels nothing in the middle, and are pushed back when it is closing the shield.

I swapped polarity, and the opposite forces are applied.

Green arrows are the direction of the force when using one single magnet as "rotor".

EDIT: I forgot to say that it was no counterforce when I tried to rotate the magnet insode the shield. After a few attemts I finally made an easy way to rotate it without the magnet getting stucked to the walls inside the shield all the time

Maybe a continous array of magnets will behave differently, as the magnetic field then will be forced from being spread in all directions around the disc magnet, into a field which is allways parallell to eachother?
