there appears to be hardly anyone on youtube showing pulse motors with that pic 2 scheme.
there is one guy that shows a more compact arrangement where you make a stack of say 12 mm i’d washers then fill the id with neo magnet/s 12mm od then a bigger washer but smaller hole at both ends making a magnetisable metal bobbin to wind a coil onto.
as in this next pic.
the idea with both transformer schemes would be to contain the flux in the core in the loop of the cores, just the core surrounds the pm in this next scheme. washers would be eddy current city tho. maybe iron filings in resin or nicely sized ferrite or powdered iron torroids stacked be better.
so on approach to tdc there would probably be a small amount of repulsion from the bottom pm to the rotor pm, but easily dominated by the rotor top pm attraction to the core. and presumably that part would be lenzless if no current flows.
then after tdc apply current to the coil so it reinforces the n-s orientation of the pm in the stator and there should be much repulsion. visualise flipping the magnetic flux orientation in each washer.
so ya only have to supply current after tdc with these whereas me hybrid concept would entail applying current with both polarities to facilitate the approach to tdc and repel hard after tdc. old mates a bit excitable but here’s the clip with the washers around the neos.
