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.

Insert a steel plate in the gap and see if it still cogs.  Steel plate provides a smooth passage for the flux.

It's not the magnetism that cogs, but the chain got more tension when the flat surface on each link rounds the pulleys. So the cogging is mechanical, not magnetic.
What I say is, if I replaced the magnets with something else, it would still cog.


A larger pulley will reduce this problem quite much.

Hi there,

As magnetic cogging was mentioned.. It is always same no matter what shape/additional magnet movements people are making.
The thing is, not much people are attacking problem root cause which is opposing force created in first place. In mother Nature this is solved really simply with 3rd force opposing 2nd force so the original force move freely.

As an practical idea, you can even take V-Gate magnet motor and add simple mod to it:
1) While magnets moving have little generator coil charging capacitor.
2) Then have coil next to magnets on stator on position where cogging occurs.
3) At the moment magnet rotor approach to cogging position disconnect capacitor then discharge into 2) coil and neutralise opposing force from the stator which is causing this.


As the result of that the initial rotationary force should go free.


Happy experimenting everyone!

Steel, iron would be better, but then what is Mu=Metal for?

Or perhaps counter magnetic influence like gravity and electromagnetic coil would be better still!

Just to remind you: The cogging in this experiment is not magnetic. It is mechanical. Each link have a flat/straight surface, and the fulcrum on eacn is placed on each side. When the links gets to a certain angle (some degrees rotation), the fulcrums for each link around the pulleys are not longer at constant distance to eachother, but wants to be slightly longer when it cannot. This will force the chain to get more tense. This difference in tension will repeat when each link pass through that point. This is why the cogging is there. The magnets themself are relatively good spaced from eachother, and not particulary strong, so the cogging is not magnetic.

I have finished 6 of the new larger pulleys. The next six pulleys will have a gear on them with the same diameter, so I got 1:1 gear ratio instead of 2:1 and 1/2 diameter of the smaller pulleys.
Also the gears will be 4 times larger than before since the pulleys are twice as large, and the gears have the same diameter as the pulleys. That means better grip, much less friction, and easier to examine the inner workings of the "motor".

Remember, I build this thing first and foremost to examine how this will work. The laws of thermodynamics is still boiling at high temperature back in my head. So I have no expectation that this invention will work as a free energy motor. But ofcourse, it would be awesome if it actually works... I have no plan B, so if it works, I don't know what to do, except share my findings as open source so anyone can build one. This thread is open to anyone, so I cant patent it anyways.

I fount the 3D-printer quite scewed, so I had to straighten it up. Printing new pulleys with larger gears.
The gears is smaller than the pulley, but that is because the gear can be placed behind the pulleys, and therfor closer to the hub.
This will also allow smaller space between the magnetic chain and the statormagnet.

Finished the large sprocket, and three of the geared pulleys.
This is going slow, but it is more to come.

Then we start over. Making a larger hub because the chain cannot get stuck between the pulleys.
The pulleys can't just be scaled down because the chain wil not fit.
I have spent more than a kilogram of plastic filament in trial and error. This piece of s**t is hard to align correctly.
New pictures with somewhat progress, but still back to square one.
First picture is the new hub.
Second picture is a sloppy test to see how far out from the hub I need to place the pulleys without pinching the chain between them. Also the sprocket (large ring with teeth on it) is too small. Resizing that one means resizing the pulley-gears accordingly. Puh...this is a pain >:(

My feeling is,  it is better to verify the working principle first with one unit of chain, pulley and stator magnet.  If it works, ie., if working principle is confirmed, then you can complete the loop. It saves lot of time and your energy (which is not free!).
