FEMM simulation showing COP 3 and 7

Funny how those incompetent in physics such as @exnihiloest and @spinn_MP are now trying to be taken seriously as competent in psychiatry. Sorry @broli, couldn't resist.

@broli,

You mentioned earlier you have an idea for a more efficient construction. Probably it would be a good idea to have @lumen try it with his Maxwell3D.

Don't know which design you actually mean, but now you mention it there is a 3d case I would like to see simulated. The one I posted on the first page:

This is not a cross section view but actually the setup. The stationary magnet has half of itself sticking out while the other half under the core. In FEMM I couldn't make the 3d transition, but the force was lower when the magnet approached the stationary from between the cores than when it left. In a true 3d simulator this by passing can be achieved.

Might be wishful thinking as it completely eliminates opening the cores AND is a continuously rotating setup. But you never know. Below is another example of just a linear case.

If opening the cores can be eliminated somehow that would increase efficiency. However, I don't quite see how that may be achieved since it is an essential part of restoring the initial state or so it seems.

@ broli, just saw something over @ energetic which could be used to separate your discs @ the appropriate time check this link: http://www.correlatedmagnetics.com/MovePath.html. Your linear design with the half shrouded magnet is very similar to the linear one I posted on page one, an air gap seems to be the key.  Here's an animated gif of the flux path hope it helps.

It's pretty obvious looking at Butch's videos there can be a gain from this concept.  I don't know why the sims are even needed to show this effect.  It's like we compute 2+2=4 in our head, but yet we need to use a calculator to convince people that 2+2=4.  The sims and the calculator step should have been un-neccessary from the very beginning.  We need to design and build, instead of debating the sims.
