Working Magnetic Motor on you tube??

[niente]

In attachment the files needed for the 13 stators simulation (not run yet). I calculated the initial orientation of every stator magnet according to the position of the rotor (they're not casual, but in latch... :-) ).
Before running the simulation you can modify the mash to obtain a more precise result.
Good luck!

@niente,
I will try running with the stator only 2mm away from the rotor, may be able to get it closer.
This is to see if I can increase the torque.
I think it will be impossile to sync by hand but once synced will create loads of torque.
With 13 stators all in sync the output will be impressive.

I was wondering if Al has tried to sync the stator, wait for it to reach its running speed, then using a screw thread, adjust the distance to decrease the stator/rotor gap, in theory the speed should increase as the torque increases.
I suspect that the reason he cannot get the stator closer is because the stator is too jumpy with the increased field strength and the sync speed may increase as a result.

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/).

Hi Niente,

Would you mind posting this animation to YouTube so I can embed it at PESWiki?  I don't like sending people to metacafe because of all the smutty video thumbnails they offer on the side.  YouTube is much cleaner.

Or you could send it to me by email and I could upload it.

Thanks for pulling this together.

i tried running your thing then got several errors after about an hour. couldnt write to file, then couldnt find poly somethingorother.

ummm just realised I layed up the stators as per jdo's cad drawing, but I think it may be wrong.

Hi CLaNZeR,

You are right. That drawing was incorrect. A bunch of other people pointed that out right after I posted the original pictures and I have since replaced the incorrect ones. You can see the correct pictures here:
