I believe that the the sliding Pseudo Solid Elements can be cog free by designing each to be connected with a second identical system but out of phase so as to have equal but opposite forces. That would leave near 100% of the rotor's work to be used external of the system. Will make drawing and post.
Thanks,

Even with more systems out of phase to reduce cogging, each system separately will cog. However, cogging is not a reason why your design shouldn't work, but several systems out of phase will ease start and stop of the rotor due to smoother run. Electromotors also cog a lot, but if there is excess energy in the system this energy should be sufficiant to keep the motor running - whether the energy are applied externally or created within the system/loop.

I have now started to question the energy required to separate and close the outer elements. I ran a few simulations with magnets, and translated into your design, it seems like it takes more energy to separate the outer elements when the main rotor are aligned vertically.
I cannot find a good explanation to this, but it seems that the potential energy applied to the main rotor in vertical position (Angular to the magnet alignment) are the same as the energy difference in separating and closing the outer elements. To me this sounds nuts, because there are not added mass, magnetism, or elements in the system to explain the difference (Which finally seems to stop the selfrun). But I will hopefully get som help by broli who are trying to make a LUA-script for calculating forces in a linear system I have simulated in FEMM. Then I will be able to increase the sample resolution in order to find a more exact average of the forces between distance A and B.
On the other hand, I have only simulated in 2D. If I had Maxwell 3D, it would be possible to simulate more accurately - I guess.

Any news here Butch?

PS! Don't let me, or anyone, stop you from trying, even if my last post seems a little pessimistic.

We are going main stream with our group's work and like any main stream business or research group we will only be dealing with people that can give use a full name, address and contact phone number. Thanks to all that have helped us over the years and check Youtube for updates on our progress. I will not be checking in here any more
after this post. I have asked Stefan to delete my profile, but he has not at this time.

I had some pieces made so I could see exactly what kind of forces were at play in one of Butch's pseudo solid concepts from earlier in this thread.  I had modified the design somewhat to make it less expensive to machine if it showed enough promise.  I found that Butch had also posted the same modified version later:

Unfortunately I am now convinced that it will not work.  That became very clear once I had everything put together.

The problem lies in the force necessary to shift the center piece from side to side.  At the time we need to shift that piece it has much metal in front of the magnets on the side that it currently sits.  On the other side, it has no metal in front of the magnets since the slot is facing them.  The force it takes to push the center piece in the direction needed is very strong.  The magnets are pulling the center piece in the wrong direction with so much force that I think it is at least equal to the force that wants to rotate the individual end pieces from vertical to horizontal (in line with the magnets).  I see no way around this issue.

Fun project.

Thanks,
