Magnet motor in Argentina

Tao
The stator is lifted at between south and north of the arc/semicircle, it is now balanced, because it wants to get to the midpoint.
Now that this stator magnet is lifted, let us take him away and take look what happens. The rotor is still balance.
The other midpoint of the arc/semicircle faces a statormagnet (N) that is down -> no torque, couse of the balancing to the midpoint
The south side of the ringmagnet faces to a statormagnet (N) ?-> attraction
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? +
The north side of the ringmagnet faces to a statormagnet (N) ?-> repulsion
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? ? =
? ? ? ? ? ? ? ? ? ? ? ? ? ? ? no torque
I don?t still see any unbalance in this setup, that is needed to produce a torque.
Sorry but I try to understand, in order to help you all, if there are problems.

the problem (easely overcome) with the track omnibus is that as the arm lifts the weel will move away from the track.... just pointing out the obvious somethimes we get so caught up in the details we forget the basics

tjanzer - i don't think up or down will be a problem.... any help down is good to reduce friction as the rotor cap drags along the top of the stator magnet but the cap/rotor shouldn't have much trouble getting the magnet down again as hartiberlin said the next magnet in the chain is on its way up wich should weeken the feild enough to allow the previous stator magnet to be pushed down effortlessly.

i dont know much about magnetic fields as in your femm simulations so could somebody tell me if i can sub magnet one (image provided) as the rotor magnet (create a ring with them in my rotor) i can not find a disk magnet at all much less one like you all describe.

correction i have found a ring magnet........ if you take apart a floppy disk drive inside the motor is a ring magnet ...... would this work in the rotor i dont know how its poles work  either......

[tjanzer]

Silverdragonrs,

Per attached drawing. N2 is on the way up. N3 is up and on the way down.
As N2 rises, it is helped by N1 and opposed by N3.
As N3 lowers, it is opposed by N2 and then opposed by N4.
Once N2/N3 are past midpoint, they will help each other but N3 is still opposed by N4.
(oops, I think the direction arrow is the wrong way).

This is why I think you may require springs to return the stator in line.

@tjanzer
yes, springs would be better into the direction to push
the lifted stator magnets again back into the track.

@Tao
yes I agree totally with your description of the fields.
I did a simulation with just the stator magnets without the rotor in it
and when 1 stator
magnet is away  the field looks like a "bar-magnet"....
so the rotor magnet surely wants to turn by 90 degrees to align with this
pseudo "bar-magnet". So the disc magnet is really the best solution and
the easiest, cause we can buy disc magnets with a hole in the center
and this will also have the lowest unbalance ( this is better than several
magnets on a rotor which have to be balanced with additional weights).

I hope Tao can soon make an animation with Bryce, so we can show the world
how the motor will work and everybody understands it much better.
Tao, if you can provide a few rendered highres pics, I can compress them into a AVI movie
or GIF animation.
Many thanks.
