A new magnetmotor idea for you to evaluate.

As you can already tell attracting the chain most likely won't work. As I see it the same tension squeezing one side together is also squeezing the other side together. Therefore no movement. In your video you use both hands to push the chain. So your chain gets tight on one side. And gets slack in the direction your pushing. Basically your chasing the slack in the chain. I see that you were able to move them a little. I have no explanation other than the magnet pulled on both side chains relieving the tension on one end.  I'm by no means and expert so everything I'm saying is guess work. Just and uneducated guess.

Probably the chain doesn't have enough magnetism in it, needs to be more massive.

I think it is enough to confirm the outcome.
That was what confused me before I built it. The idea of operation is described earlier. I did expect that my wheel with two angled discs would find equilibrium. And now I know how it does that, and why it does.


Because, if the seesaw hadn't expanded near a magnet, I could build a magnetmotor that actually worked, but the outcome of the experiment proves that it cannot work.


My goal is reached - learning by practice


New ideas must be explored.

I've decided to move forward with this design. See the image. I have given it a lot of thoughts. I have concluded that the seesaw will not work, because the magnetism pulls the chain towards it, and squeeze the opposite end together.


I think something similar will happen with the design in the image. A long magnet will attract the green chain more than the orange chain. The X'es is where the chain rounds the pulleys. The left side X'es is pulled towards right, and the right side X'es are pulled towards left.


When the wheel turns clockwise, the chain moves towards right to fill the widest gap between the two wheels. So the chain is sliding away from the magnet at the right side, and apprach the magnet at the left side.
My guess is that the magnetic force on all the X'es combined, cancels out.
What I got left is longer green chain than orange chain.


It's a complicated build, mostly to put the chain in place.

Printed out som pulleys for the project.
I have also finished the rotor, but have no pictures of those right now.
These pulleys is made for that zig-zag chain I have posted an illustration of earlier.

Picture of one of the finished wheels - actually spokes, but it saves a lot of 3D filament, and time.
It takes almost 6 hours to make ONE "wheel" of this type.
Printing 16 pulleys took more than 7 hours.
You need to be patient with this hobby  


Edit: the M5 bolts and washers are made of non-magnetic stainless steel.
