If you print 2 of UFO's drawings cut the rotor and armature from one (not the brushes)
and superimpose over the other and slowly turn the superimposed one in the direction of rotation you will see where the coils are in relationship with stator magnets when the brush just leaves the comm segment and do not forget that the polarity of the coils are reversed and imagine the reaction between the two you should remember that magnets either permanent or electro will try to align each other.
Remember though that the brush and comm segments really need to be the exact size in relation to the real motor so you might have to pull the motor apart to get some exact measurements and that there usually more than one comm segment touching the brush at one time usually 2 sometimes three
Tell us your results
Kindest Regards
Kogs been there done that
