if you increase the number of magnets, then its going to be more slower because the push and pull of the magnets will be slower. 2 pole motors or 2 magnets in stator allows for extreme speed and Rpm, because the pushing and pulling force of the magnets is rapid and very rapid, this causes High speed rotations. so in conclusion, the more poles of magnets you have, the slower the motor will be, and the lesser the magnet numbers or number of magnets, the faster the motor.
why do u even bother to give us the links to some while the actuall motor core we have no idea where to get it and plus some other stuff like its a shame cus I want to build but can't
