I didn't  understand the working concept but as for as my experience, you need a tangential force to rotate a pulley or a wheel.  In your shown figure, the stater magnet will simply push out the repelling portion of chain and pull in the attractive portion of the chain. There is no tangential force to keep the pulley rotating.  ( if I have got it right)
May be I am wrong.  Wish you good luck.
That is actually a very good explanation, and I believe it is something right about it.
So, what you suggest is that if I push on the vertical chain, I can push as hard as I want without turning the rotor?


I must remind you that it is a gear at each of the bottom pulleys that will get a tangential force from the stationary sprocket, shown in the image earlier, which will force the pulleys to turn and wind the chain into constant position when the rotor turns. What do you think?

For turning the rotor you should have a tangential force on the rotor which operates rack and pinion arrangement (gears) to rotate the
pulley.

Yes. I know. I will figure this out in a few days. I received the ballbearings today so I can complete the build.
Then I'll do some mechanical tests, maybe just use the air compressor on the vertical chain parts to see if the rotor will turn at all.
The stainless steel ballbearings will be put in pairs for each pulley to reduce friction. Easier to tell what's going on that way.

Like a glove. Testing ballbearings.

Mounted all the bearings. 48 pcs in total. The 6 teeth pulleys are too small. The belt is cogging a lot.
So I redesign the rotor to have larger pulleys, 12 teeth, and twice the diameter.
This will reduce cogging, and I can choose a 1:1 gear ratio which means a lot for better grip and less complications. However, larger pulleys might force the chain to twist more at shorter distance.
Here is a video that shows the cogging.
