Any flux movement of the Halbach array would delete the arrays designed affect if not evenly done so. This takes away from what is needed.

The more I think about this, the less apt to playing with it I become.

Good luck

I do hope to post a much easier way soon. I am still testing my theory.
The halbach cylinder is fixed. I have made a better/new drawing which shows the path (white circle) the leading outer corner of each magnet in the rotor is following.

Maybe it doesn't help much.

I found that the force needed to flip the magnets as they go is counterforcing. Exactly how much is not known as there are too many factors for my brain to handle ;D

That is why I have chose not to play with it. My head hurts enough already. LOL

I finally figured it out. I found that the "flip-distance" versus torque, ended up in 100% of all the torque available is used to flip all those magnets. So therefor there will not be any torque left to run the rotor. What a discovery... f...ck!!

LOL ;D

Case closed.

 Don't give up yet. Just remember that an array must be created to have an uneven field and the runners have to be unevenly numbered but an even combination must be added to the mix to make it work.  ;)

I just gave you more then I should have and if you don't understand what I have said, it will be more clear after I am done building my proto type.

I see the picture - I think. Anyway, to make anything work, the magnetic density must be constant uneven around the runner to force it to run. So far I haven't figured out how to do this without electricity. I hope you don't go silent if you figure out your prototype does not work...

Good luck.

I'll go and play with my magnets again...
