3D printing a structure for an experiment with magnets

[Low-Q]

So, I am finishing making the parts. There is a problem with the size. It is too small, and my 3D-printer cannot make the parts, specially the gears, accurate enough. So it is hard to assamble the parts correctly. A printer like this will "bleed" a little extra material, so the parts gets slightly larger and rounded than I want to. The smaller the objects the worse.


So therefor I scaled it up about 250% so I can use the big magnets instead. Hoping for more accurate parts, so everything runs smoothly.


I have wasted my night with a very poor sleep, being thinking, thinking, thinking! Heart beating fast etc. Not good. I guess the excitement has a part in my bad sleep. Maybe I get a heart attack if this thing work...or not work. Let's not hope so
What to do if it works? How can overunity possibly be so simple to achieve? What should I say to friends and family without making them believe I have to be hospitalized for being nuts? What about the government? This was questions I struggled with this night, along with a lot of others...


I watched a video of Reidar Finsruds art "Perpetuum Mobile", and suddenly realized (I assume) why his device actually work.
Those three long rods hanging down might be some way of removing, or reduce, counterforces or torques, just like I had in mind with my own rods attached to the outer magnets to prevent them to work against the rotation.


At the same time, I am very sceptic and do not believe in over unity, but I have the tools to build this thing, and hopefully learn an important lesson - whether if it's working or not.

This is my first model - the small one at the very beginning...

This is the second attempt with 250% size. Gear and the block is parts of the inner rotor. The three equal parts are holders for the outer magnets. The actual outer rotor must be printed later due to lack of printing space:

Thanks for the kind words webby :-)

I spent most of the last night considering the rods functions as a whole, and couldn't find a reason why this wouldn't pull it off. The primary function is to keep the outer magnets in orientation, and I was probably on the edge of a nervous breakdown...
The idea might not solve anything, but the reason I was thinking of rods is because:

- The outer magnets, if they are free to rotate, they will rotate in the same direction as the rotors. To prevent them from doing that, I first thought of a gear that was connected between these and a stationary gear that surrounds it all. The gear ratio should be correct so the outer magnets kept its magnetic orientation.
The gear-solution would (more obviously to me) have a direct connection to the rotating system. And since they then will rotate counter, relative to the outer rotor, this would have a direct counter torque added into the outer rotor.
In simulations, the sum of this counter torque is 50% of the counter torque in the outer rotor, resulting in a total counter torque if 150% higher than the inner rotor. Since the inner rotor spins 150% faster, the total energy in both gears will end up with the same and opposite. That does not work - obviously.

So therefor I had the idea of controlling the outer magnets counter torque without touching the rotors at all - using external rods connected to the outer magnets.
If I used very short rods, and pressed one rod with my finger to the left of the left hand magnet, the torque so close to the magnet would eventually cause the rotors to go in the wrong direction- almost like pushing on the magnet directly. However, on the opposite side I would push with the same force, also on the left side of the right hand magnet, and cancel the first force.
With gears, where the "angel of attack" will shift from left to right side depending on if the magnet are located on the left or right side of the rotor, just as if I pushed the left hand magnets down and the right hand magnets up. This will not be the case with the rods, because the force is pressed from the same side all the time causing the counter torque to disappear. That's the idea anyways.
Having that in mind, I figured out that the length of the rods in that perspective was not important, but If I do not want to be a part of the system by hand, I chose long rods that goes through a hole some distance away. Those rods will move as pistons in a linear fashion (almost), not rotational - like the pushrods on a locomotive.

A better, and probably less complicated solution, would be to connect each outer magnets with gears, so I only need one rod - and not one rod for each magnet. Because two or more rods must cross each other per revolution. That would eventually cause the rods to twist them self together.

That said, words are empty or false until a practical experiment confirm or disprove the idea. I have no expectations (well, I have just a little) that this will work - it works so fine in my head :-)

Good night. It's late (11 o'clock PM Norwegian time)

Here is a design that is based on the magnetic interaction of thin magnets to the back side of opposing magnets.
It seem that when a thin magnet overhangs another thin magnet the back faces cause a huge change in the normal result.
Even opposing faces will attract with enough overhang.

Check out the simulation!

That is an interesting design Lumen.


FEMM does not simulate the Z-axis, only X and Y axis. So I'm afraid this device has to be built... I do not have so many small magnets, but I have 20 pcs long ones that measure 50 x 5 x 2mm, magnetized through thickness.
