ABSTRACT:
A stepper motor having a permanent magnet rotor rotatably mounted within the annuli of a stator winding and a bias magnet. When the stator winding is not energized, the rotor assumes a home position established by the bias magnet. When the stator winding is energized, the rotor is rotated away from the home position by an angular displacement determined by the winding current.
