Magnet-motor - another design

Here are the pictures

A Femm simulation may be able to show wether this can work or not.
It should be interesting to see what happens when the rotor reaches the point where it lines up with the stator poles.
The torque will probably reach zero at this point.
Once it crosses this point the like poles should repel each other allowing the rotor to proceed onto the next stator pole.

Hi Low-Q,

One question, before I analyze... 
You want to fix the multi-pole magnet on the rotor, or independently above the rotor?

By the way, it is a different idea either...

Hello Vidar,

When the rotor arm reach the center of the stator arm, how does he gets kik out of that center.

Can you explain a bit more!

Thanks    Joe

Well the center magnet stands still as the outer magnets do. So the idea is that the iron in the rotor is magnetized depending on position - as in a regular electric motor. When the rotor arm is in center of the stator arm, the rotor arm has no magnetic force, so there will probably be a sticky point right there. Hopefully, the rotor, in the position shown, will have enough torque to push the rotor arm beyond the stator arm.
Hmmm...tricky.... What happends when the center magnet is tilted 30^O, instead of 45^O as shown? By second thaughts, 45^O is not ideal - for magnet motor or regular electric motor.

I'll think about this a little more

The idea is that the multi pole magnet and the stator magnets are non movable and fixed to a plywood piece (Any better idea than using plywood?). The iron rotor, which is made of multiple "sheets" of iron - like in the transformers - will be fixed to a ball bearing fixed (on another piece) on a rod in one end, where the iron rotor surounds the multipole magnet very tight (0.1mm or so). Have you seen these brushless outrunner motors for model airplanes? About the same principle as that.

Some iron is also applyed to the outer stator magnets, so when the rotor approach, the outer magnet will not magnetize the rotor to make a sticky point, just to maintain the repelling force when the rotor arm (Hopefully) can pass the outer stator magnet.

Now - analyze!!
