This is really interesting Vidar! I'm looking forward to seeing the development of your idea!!

If somebody have a good idea on how to make good gears, let me know. I need a 4:1 gear ratio. Each pulley have 6 "teeth" that fits the belt links, but need to wind "backwards" (relative to the rotor) 24 links of the chain for each 15 degree turn. I printed a small gear, but the 5mm shaft is almost too wide to get any solid material between the teeth. The gear version in earlier post with 10 teeth is too big and will wind back only 12 links. And then the polarity swap on the belt will move 1 degree forward while the rotors turns 2 degrees. I need 0 degrees motion of the belt itself.
I can print with a smaller nozzle, 0.1mm, to get presice small gears with more teeth on it, but I'm afraid the plastic gears will stuck on the circular stationary teeth array that surrounds the rotor.


First test will be without winding gears to examine the concept more easily. Only a thread attached to the belt that I can rewind with.

Working with neos is a pain. Finally finished approx 2 meters of magnetic chain. All that fits on a 25cm diameter rotor...
However, it is obvious that the spokes needs reinforcement.
The whole chain compress the pulleys towards eachother.
Attached pictures of my "christmast tree".
Haven't received the statormagnets yet.

I'm making a 18cm diameter, 36mm hight cylinder. This will be placed between the rotors so the spokes doesn't get bent towards each other.
Hopefully that will work better.

Just bought 6 lots (60pcs) of small ball bearings. Stainless steel. High rating at Aliexpress, so I guess they're good - and hopefully not ferromagnetic.
I'm afrais the plastic pulleys will grind themself into the bolts and lock up totally.
I also got a confirmation that the statormagnets has arrived the local postal office :-)

Ahh...statormagnets have arrived. 40pcs 100x10x5mm and 20 100x20x5mm ferrite magnets. Actually quite powerful.
Now, the build of an arch used as template to arrange the magnets to a cylindrical statormagnet.

Testing the chain. Much friction between the plastic pulleys an the 5mm bolts I'm using as axles.
Looking forward to receive the ball bearings.

I marked the magnet-chain in red and blue. Then stumbling throug an explanation in english.
This video just shows how the chain winds backwards as the rotor goes forward.

Very cool build, it looks like a piece of kinetic art. Hopefully you meet success.

Thanks Broli. It would be very cool if I pull this off - and with open source like this forum, anyone can replicate it - no patents, no requests for investors for million dollar foundings ;)
I have still not found mechanical reasons why it can't work, so time will show.
Still waiting for ballbearings, and the build of a statormagnet hasn't been started yet.

Testing rewinding gears. This is a 10T gear. Maybe 8T is better, as the teeth gets larger with better grip.
Still waiting for the ballbearings to arrive. I have the tracking number, so they are on its way.

The bearings for alle the pulleys has arrived Norway, and they are hopefully in my mailbox this evening or tomorrow.
No new pictures this time.
I can however say that this concept has been posted among people with good understanding in physics, and they cannot tell where or what will stop this motor from running. At least it gives me hope that there is a concept that no one has ever thinked of before. Something new. If this motor doesn't work, I am still happy to know that the concept has never before been published, even though I might think that someome in the world should have had the same or similar idea before me.


Best of all, if this thing works, the idea and the construction drawings are already public, and open source. But I wonder if it is legal for someone else to patent an idea that is already public domain. I have no plan for patents, but I am afraid if someone patent the idea in their name, and restrict everyone to replicate or build this for commercial use - for example in places where electricity is not possible to make, but can assist in making waterwell-pumps or generators in poor dry countries.

Hi Vidar

A device or method cannot be patented unless it is new.  Once published that device or cannot be considered as new.

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.
