Abstract
A hybrid stepper motor includes a stator having a number of poles. Teeth are formed on the stator poles and separated from each other by slots. A magnet is inserted in the slots to a predetermined depth from a top surface of the stator teeth. The motor further includes a rotor that is provided coaxial with the stator. Teeth are also formed on the rotor opposite the stator teeth. The rotor teeth enable the rotor to be rotated relative to the stator in cooperation with the stator teeth.
