Gear-magnet motor. Just a strange idea

[Low-Q]

Hi,

I have been thinking on a motor that works on the basics of a gear pump. Attached animations shows a magnetic gear motor. The outer rotor is made up of steel. This steel is rotating, but an external and fixed magnetic field is magnetizing it. The eccentric rotor inside are magnetized externally with the south pole.

Principle of operation:

In the right side of the motor, there are repelling force that want to expand the space between the eccentric rotor (S) and the outer rotor (S).
The left side of the motor, both the eccentric (S) and the outer rotor (N) wants to close the gap between those rotors.

Both these actions will force the rotors to rotate in one direction. In the area where the eccentric rotor tooth must go from N to S in the bottom, and S to N on the top, will hopefully cancel eachother out, so it will not prevent the motor to start running.

I have not tested this, and wil probably not. I have no 3D magnetic software to simulate this.

Any opinions, thoughts are welcome

I was thinking about something:

The inner rotor is allways rotating faster than the outer rotor. This allows the inner (eccentric) rotor to escape from the repulsion part, and approach the attractive part - just as it should. There will allways be a difference in magnetic flux density so the inner rotor will chase its equilibrium, but never finds it. Hence the motor will run untill the magnetism are gone (?).

It's an interesting concept. I see it not working as shown but if both the rotor and stator are rotating and of laminated steel, it sure seems it could work.
A shift of the field change area of about 22.5 degrees on the stator and a small area of blue on the rotor to start the repelling with the same pole before the switch to the red area.

Not sure, but it can't work as shown because it is moving into red from blue and it will want to attract back to the blue area at that point. I think you may be close to something!

I disagree, I think it may work as shown because it seems to be repelling and attracting enough to get thru the gate. It's definutly worth exploring.

I can agree with this, but this counter force also applies the opposite way on the top of the rotors. The case is that the outer rotor are forced to the left, and the eccentric rotor are forced to the right. This means when the bottom part of the eccentric rotor moves from blue to red, it is in some extent conterforced by the movement from red to blue on the top. The top of the eccentric wheel are facing this change fron red to blue 20% faster than it does on the bottom. So the energy that should prevent rotation, might seem to be less than expected - even zero...

Also take into account the difference in RPMs. The difference are about 20%. The torque should be equal on both rotors (Force equals counterforce), but the energy should then be greater in the eccentric rotor as the RPMs are 20% greater than the outer rotor. Could this difference do any good? Could this mean that the efficiency are 120%?
