180 degree swapped radially magnetized rotor - magnet motor

[Low-Q]

Hi,

First I must say: I do not claim overunity in this post - the following experiment must be examined further to determind what the practical outcome will be!

I have played a bit with FEMM again. So I came up with an idea that is based on radially magnetized ring magnets. But in this model I will show you two half magnet rings which is magnetized radially opposite of each other and attached together as a normal ring. This magnet is from now on called "rotor". There are 8 pairs of round piston magnets magnetized through diameter. These are the stators, and might be made simpler or as single magnets.

I played a bit with stator magnets around this rotor, and came up with something that appears to make it possible to shift polarity of the statormagnets without adding energy. The stator magnets are paired and linked with a gear - if one rotate, the other counter rotates. Each pair points in the same direction except at the point of the rotor where the polarity shifts. At this point the present stator magnet pair do not contribute with torque. So it is convenient to rotate these stator magnets 180 degrees at that point, as there is (Probably) no forces that will prevent them to rotate and shift polarity. The net force required to do this appears therefor to be zero at this point. As the rotormagnet continues, the recent rotated statormagnets are locked by a track as all the other stator magnets are to maintain their position untill polarity swap occours again.

At the point of polarity swap, the statormagnets will suffer from counter force the first 90 A due to the polarity of the rotormagnet at this pont, but the next 90 A will ofcourse make up to it, so the net force, or energy, required to swap polarity is probably zero.

If this is true, this model at 40cm in diameter (rotor) and 10cm deep, N40 magnets all over, have an average torque of 85Nm according to the simulations. All torque measurements are on the same side of the scale.

Attached there is a FEMM file to play with, and a picture to show you the idea.

Just be sure to swap the polarity of the statormagnets that is in the area of the polarity swap in the rotor.

The iron ring around it all is present to minimize simulation error due to limited simulation space available. I could increase the simulation space to infinit, but then it would take infinite of time to simulate...

Enjoy, and please take notes and comments to this idea. I cannot see the flaw (if present), so please be honest and critical

Looks complicated... But this "rotor" can realy rotate?

[Low-Q]

The rotor is the solid ring. As the ring rotates the stator pairs will not follow around, but rotate separately 180 degrees when the point in ring, where polarity are swapped, passes by. All magnets in the ring are fixed or glued to a plastic tube. And that tube can rotate inside the stator magnets.
I'll try to make an animation.

Here is three pictures showing the polarity swap of the stator magnets. Too much fuzz in making an animation.

PS! For those with open eyes, the rotation of the stator magnets are wrong (Opposite) in the drawing, but I didn't mind doing anything about it. It should however not make any difference in total.

What is the force that makes the rotor (ring) magnet rotate? Magnetic attraction? Magnetic repulsion? An external force?

Sorry, my brain is not good interpreting complex drawings.
