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

let's have a look what Vidar has, If he has anything on the device other than a link I am sure he'll share it with us. Until then   PATIENCE

Yet another "working" device and yet another link gone?  I think I am starting to see a pattern here. I am not saying MIB but, after dealing with the info on xpenziv's design, this is getting old.  for once, I would like to see a design that works, and can be replicated, and, the designer/inventor says..."here is how you build it.'  Am I asking for too much?

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.

As I have already mentioned many, many times, these magnet-to-magnet motors such as the one discussed here (a typical motor of this type) are very difficult to tune up. Mechanically they seem symmetric but their fields, and that's what matters, are not because the seemingly equal in shape magnets have quite differing forms of their magnetic fields. The FEMM simulation is of fields with idealized form which can never be achieved in practice as easily as one may think. Because of the unevenness of the magnetic fields in these seemingly equal in form magnets, cooperative phenomena take place and super poles are formed which destroy the nice pattern seen in the simulation and always bring the rotor to a stop at the overall potential minimum caused by the mentioned cooperative phenomena.

Therefore, as I said many, many times, the way to go is towards constructions whereby magnet-to-magnet interaction causing the above-mentioned cooperative phenomena is avoided and is replaced by magnet-to-steel interaction of the SMOT type. A very creative application of the SMOT principle is found in @xpenzif's rendition of the problem. No wonder why @xpenzif's device is the most promising so far. The magnet-to-magnet motors can also be made to work but the adjustments are Sisyphus labor. Who needs that? Of course, a straightforward practical solution of the problem is by applying brute force as in the Butch-Sprain-Honk type of device. As a scientific experiment, however, so far @xpenzif's device is unbeatable in its simplicity and potential to be reproduced.

I have unfinished work on magnetic motor on my web:
http://free-ri.htnet.hr/Branko/04.html

It is just linear movement principle. I didn't finish that work, because of some other investigation of Nikola Tesla's work in energy device:

For now, investigation in 'cosmic ray' energy capturing system is in my mind.

If you have enough magnets, good luck! Left/right mechanical movement is only mechanical problem (and gap in that part).

I must say that link disappeared quite quick. I was initially looking for the FEMM-site in Google, and came across this link. Well, I downloaded the whole thing so here it is:

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.

The sum will be very high, so remember to devide on number of samples used. I get allways an significant positive average no matter how I look at it.

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