Working Magnetic Motor on you tube??

so the stator is supplying torque?

I would simply say that in this configuration the rotor receives a push from the combined magnetic field of rotor and stator.

In attachment, the FEMM simulation file and the LUA script I used to automate the process.

Here's a simple analysis (by using FEMM) of the torque of the rotor covering 45 degrees of the motion (then it repeats itself because of the symmetry).

When the fulcrum of the rotor and of the stator are connected with a line, and one of the magnets on the rotor is perpendicular to this line, the stator position shows a difference of about 25 degrees in respect of that line (as in the third Alsetalokin video). This fact is included in the simulation (visible here: http://www.metacafe.com/watch/1060658/oc_mpmm_magnetic_simulation/).

The simulation data and graph are included in the attached Excel document, and they show a total positive torque (it should be 0 if there were no self-rotation!). 

Sorry for any mistake I did! 

Verry interesting! I wonder if it would be possible to do this with an 18" rotor with all 13 stators in place, using gearwise rotation at the same rotation ratio. And could you post the FEMM/lua scripts as well?

Hi

What if the rods are turn different in rotor, and if stator n are up,   s are down all 3 or different ?
then it is a lot of combinations to test or have i wrong?

Very impressive.
I have been following this thread for about 4 days now and have a suggestion based upon a "vision" I just had.
What I am picturing is a simple and ancient flyweight assembly on the rotor to govern the optimal speed upon "latchup" of the stator.
It would simply be a braking mechanism to keep the rotor from overreving and having the stator lose sync due to the overrev.
CLaNZeR's setup would be best suited for this vision as the "brake drum" could be attached to the top crossbar.
One could also measure the heat being emitted from that also with a thermocouple to get an indication of energy output.

Anyway the above is just a thought for "down the road".

Keep up the excellent work guys.

@ezzob,

I don't think that's the case. You may try it yourself--take two of these magnets and see that when they are repelling when placed parallel this won't change if you turn them around their axes. You can also measure the kgauss and see that there's a midpoint line on the cylindrical surface where the sign changes the same way all around. The shape of the field around the magnet may not be symmetric, though, and that's the main problem. Also, as I said a while ago, I'll be doing some experiments probably on Sunday with a batch of virgin magnets (that I've not used in my machine) and will compare their behavior to the rotor magnets I've already used to see if there's any discrepancy along the lines of eddy current degradation mentioned by Stefan. I saw something strange when performing the test suggested by @MeggerMan.

@MeggerMan,

Have you tried your repulsion test on rotor magnets which have already been in the rotor while carrying out experiments? Is the sameness of behavior when testing them SS verusus NN retained? And in general, does this 31mm remain the same?
