Inside the metal shell, the Bachin housed a permanent magnet rotor—a toothed cylinder of magnetic iron—sitting amidst a set of wire-wound coils (stators). The magic of the stepper motor lies in the principle of discrete magnetic alignment. Unlike a standard DC motor that spins freely when power is applied, the stepper resists movement. It wants to stay put.
