Magnet motor idea - again.

I will build a circular prototype with speaker magnets. Cut them in half so one side has opposite polarity.

Hi Vidar,

I wonder what tools you can use for cutting the magnets.  I assume you use diamond cutter disk run at low rpm? 

I think there are some members here using Maxwell 3D, unfortunately it takes time to create the model and then more time to run the simulations.

These magnets are hard to cut, anf dust from the magnets will be hard to remove. Actually, I want to stack 3 magnets upon eachother, and align them to make that shape (Except the shape at the back side will not be flat).


The upper and lower layer of the stationary magnet will at first repel the tip of the moving magnet when the assamblies mesh together - at the same time as the upper and lower layer of the moving magnet is attracting the stationary assambly.


Sliding the moving magnet along the notch/pit is (should be) easy, and the tip of the moving magnet will in the center start to attract the other halfs upper and lower layers for a short while (I know this by my first experiment - i don't know why that happend exactly, but I have a theory)


And then after sliding a bit more the tip will attract to these layers at the same time as the upper and lower layers of the moving magnet repel just as much.


Therfor it is easy to separate them where repelling forces will suddenly become greater than the attraction of the moving magnets tip (As shown on youtube).


I must use some tape between the layers of the stationary magnet so there is space enough for the tip of the moving magnet assambly to enter the notch/pit.


This far it seems there is three places where positive gain is present. I can't find out where there is opposite forces which accounts for the gain.

I just want to confirm where the sticky spot is (if it is present), as I am in general pretty sceptic to overunity... I am a little exited though :-)

Maybe the way these magnets are aligned is a way to avoid the sticky spot? If it is, I will be a dead man tomorrow :-(

Hi Vidar,

Just try to build it, that is the best answer. No amount of talking / rambling can give real answers.

If you still happen to find one or two sticky spots, then it is still a good step to use small electromagnets at those spots IF the permanent magnets would give the rotational torque during most parts of one full rotation.

I am on my way gluing magnets together. They are so cheap so it would not be much economic loss anyways....normal ferrite magnets, as they are easier and safer to handle ;-)
