Working Magnetic Motor on you tube??

Anyway what you can do is just run this script (set the properties to mm first) and wait.....for about 7 hours :

er. ok i have the program, but i dont understand how to input that script. the only script stuff i see is lua scripts. i added that to a text file and called it .lua and it didnt work. how do i load it?

and sorry, i was talking about the video, not the graph

@Evil,

Easy peasy lemon squeasy:

1. File -> open "ocmpmm01.FEM"
2. Problem [change Length units to mm and set the depth to 10]
3. File -> Open lua script "ocmpmm.lua"
Also be careful not to click the white workspace or you will leave an unassign node (small square), if you do, then use the undo button.

It will run automatically.
Use the script that niente posted to exclude the bitmaps being saved.

doh, im sorry, where is the fem file?
nevermind, i see now

sorry one last question, i WANT the bitmaps for an animation, but they only have a single field line per magnet, if any. they look nothing like the video posted earlier?

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! 

Please forgive me ahead of time with this question, but aren't the lines of force on the stator 180 degrees out of sync with Al's third video?
