This is a, in theory, a working magnet motor. VERY cool!!

Anyone can try to run as precise script thay want - there is two suggestions in the RAR-file - you'll every time come out with positive torque. Use Notepad to alter the step values in the LUA-scripts.

Don't rely to FEMM simulation results ! It's far from real world. Though FEMM is the best freeware simulation software available today.

You're right, but some excitement doesn't harm anyone Just download it and see that it works in FEMM. What ideal "bug" in the software is making this device working? I have no answer except FEMM is not a 3D simulation software. However, to make two magnetic lines interact with eachother, they have to be in the same dimention, so 2D will do for the simulations.

Hi,
avoid to make the mistake to add discrete momentas insted of integrating the functions of tourque and add them.
My opinion without seeing this device: sumM=0.
Why: the peaks contain more area between the lines than the lower values.
See eden project magnetic therory.
Good day

I have done this error many times, but are learning - eventually
I use the Area-tool in FEMM to measure the torque. And that function allways measure in the correct direction. Other ways is to make a circle around the rotor and mark it with the Contour-tool, but if you mark the circle in oposite order some times, the measurements will fu..k up.
Note! Using the Area-tool requires that the rotor is allways rotating around the 0,0 point in FEMM - with Contour-tool this is not necessary if you remember to mark the two half parts of the circle in the same order every time.

I have ran the LUA-script on many other projects I have in FEMM, but the result is then allways 0.

To be sure, make measurements for one complete revolution.

Simulation has to be done in 3D because the nearest neighbors must not be neglected and not all of them are in the same plane. Try using Maxwell3D. Probably, you may ask @Jdo300 here to help you in that. He's an expert in Maxwell3D.

I don't mean to jump to any conclusions because, maybe the link is bad or a server is down....that happens.  I still have hope.
