Gear-magnet motor. Just a strange idea

[Low-Q]

I am really exited about how this discussion has turned. However I am not responsible for the possibly waste of time if this concept turns out to be a none working one - my initial one or the ideas which has showed up lately. That said, i am very exited, problems with sleeping, headacke etc. . The essence are boiled down to the torque and how the gear ratio affects the general design. Thanks for your time this far. Meanwhile I will try to make a motor with the equipment I already have. Wish me good luck, and fingers crossed:)

Here's some more fuel to the fire. Attached are some renditions of a more engineer friendly design. The clear acrylic plastic can just be  wood. I also would just use coils initially to cut cost down and try to  have a proof of concept asap.
   
I hope Clanzer can get his service going soon. Most of the time money  is not the problem, it's how you spend it and where. We could even split  the bill on an promising open idea. This is what true open source  collaboration is about.

Have you simulated on these new designs? I cannot see how this can work. I see no torque (?)

Very nice pictures you got! I believed a moment you actually had made a real model already

Anyway, if it is this simple to build, I have all I need to make one quite asap.

EDIT: Now I see how it works - I was just blind for a moment.

For future reference, attached is the simplest form of how this concept works. This should allow everyone to understand the concept.

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. 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.

There is also another problem I discovered this morning - the truth finally hit me hard and brutal :
I was simulating further on my own idea. I have done a terrible mistake by a mistake choosen wrong material for the outer gear. I have used a neomagnet material with fixed polarity horizontal regardless of rotation, and not the iron material I was suppose to have. When I swithced to iron, the torque are now in average 20% greater on the outer gear compared to the eccentric gear - exactly what it "should" be... However, still no sticky spot which is the only good thing left after this experiment.

I say this now as early as possible (It's now 11:30 AM where I live), so you do not have to waste more time on this. Unless you guys want to experiment further with switching polarities without a sticky spot. I will too.

So I have tried many different ways to keep the properties of a permanent magnet by changing shapes, materials etc on this outer gear, but are not able to replicate the properties of the outer gear as a neo magnet. The magnetic field inside the iron takes a different path when only magnetized from the outside compared to when it was a neo magnet with its own "controlled" magnetism. This is the reason this experiment did finally fail. I am really sorry for wasting your time on this.


I have however another hope in mind which is the posibility to make a homopolar motor with several windings to decrease current and increase voltage. I will experiment by turning the outer gear into an electromagnet, keep the outer permanent magnets as usual, let the windings be fed by pure DC current. The hope is to make an equivalent to a permanent magnet (Like the mistake I made), and then make a motor which is brushless, running straight from the battery without complicated electronics.
I will make a simple drawing of this and post here later.
