most simple design of a permanent magnet motor. what are the odds?

sorry i'm new

It will stop at the point of lowest energy consumption. The stopping position in your case can easily be seen. Just rotate the main rotor about 10-15° and there you have it: each N-poles of the rotor is between 2 other N-Poles. It will never overcome them.

Even if you change positions of the permanent magnets, it will always find a position where it stops. It's just the way it is.

okay i see the problem. is there a way to shield the magnetic field while the north poles approach each other until the repulsive force points in my desired spinning direction? or at least weaken it so that the repulsive force in my spinning direction is greater then the repulsive force that wants to stop the spinning?

even shielding in your design will not help sorry

well, from what i have read is that some materials absorb magnetic field lines thus making the magnetic field on the other side of the material weaker or not? isnt that the effect we need to make my design work?
