Gear-magnet motor. Just a strange idea

[FatChance!!!]

I'm so sorry that I was right in this....
When will we find the path to overunity....if ever?

I wish you the best of luck even though I sincerely believe you will find out
that you missed some important data in the simulation and there will be no OU.

I have done a terrible mistake by a mistake choosen wrong material for the outer gear.

This particular design has a problem. The steel pieces are busy with guiding the magnetic flux between the donut-magnets on the outside, and will therfor not have a magnetic flux that is looping from N to S on the outside - which is essential for affecting the cylindrical magnet on the top (and bottom). I tested a small linear model yesterday. I used a steel ball instead, but that does not change anything. It feels a sticky spot where the donut magnets are shifting polarity.

The interaction between the ferromaterial and magnetizing PM or EM is irrelevant. This interaction is completely symmetrical and thus cancels out.

Also the steel ball does not attract or repel the cylindrical stator  magnet on the top. It seems that the steel ball does not "see" the  cylindrical magnet at all.

I had different results. I used a cylindrical shape ferromaterial between ferrite magnets (with an air gap to allow movement). When I approached it with a neo I could either push the ferromaterial slightly or attract it when it clearly wanted to stay in the sticky spot. However there's a threshold, if you get too close the ferrite loses and the ferromaterial  will always attract to your approaching cylindrical magnet. It's subtle but it's there. That's why the engineering model has adjustable slots for the cylindrical magnet.

You shouldn't think too much about flux trapping. Because the ferromaterial essentially becomes a magnet, if you look at the coil design the ferromaterial will have maximum magnetization because it's positioned in the middle of the coils. Whereas the field of the outside magnet is so weak and dispersed it has little effect on the MAGNETIZATION aspect, but it will still interact with the ferromaterial if it was a magnet.

Here is the idea with the coil instead of a permanent magnet outer rotor. The coil are stationary winded like you see in the drawing. Axels to each rotor are able to exit through the windings. If this electromagnetic outer rotor have the same properstis as if it was a permanentmagnet, we have sucessfully made a "homopolar" motor and solved the problems with brushes, high current, low voltage, and low efficiency.

How can they cancel out when the steel poston at the top and the bottom are approaching the same scenario? I see that the polarity are opposite, but it is opposit in both the cylindrical magnet and the outer donut magnet, so the bottom steel cylinder will "see" the same forces as the one which is approaching the top. The sticky spots are rather adding up than cancelling out.

Why did you ignore the part after the steel leaves the sticky spot. Surely you would have seen this in your experiments. When you arrive at the pole switch there's your mentioned sticky spot but once you make it through the steel is pushed out of the sticky spot. So +repulsion -repulsion = 0. This is magnetics 101.
