LibreEnergia, respectfully I believe you did not read the OPs post correctly. It appears that the OP is asking whether it is possible to derive enough power from a single turn of a PMM to be able to use that power to escape the sticky spot.

Perhaps a generator driven by the PMM could be geared many times to 1 where it could store energy in say a cap and that energy released via a coil at the gate. There are some examples of PMMs giving very good torque on a single rotation.

I would say it may be possible regardless of magnets having conservative fields.

I did read his post correctly. Simple conservation of energy principles are enough to dismiss the idea of gathering energy during the rotation to provide enough energy to escape the 'sticky spot'.

The integral the forces with respect to distances travelled over a closed path in a magnetic field is zero so,  If you try to store energy during some part of the rotation then you convert kinetic energy to stored potential energy. As you approach the 'sticky spot' you then convert that potential back to kinetic energy.

Due to conversion losses the amount of energy you store will ALWAYS be less than the amount of kinetic energy the device had in the first place. So if you convert the stored energy back to kinetic energy (incurring further losses) and then try to surmount the 'sticky spot' the end result is worse than if you didn't try storing any of the energy in the first place.

It just doesn't work.. get used to the idea and try something else.

I agree!
So, what needs to change to make something operational.
It's all about the field lines and their direction at all points of movement through them.
It seems there is a way to start at some point and make a movement with and energy gain, only to end up at a the same condition as you started.
It should be impossible, but there may be a way.
