Abstract
A step motor having a rotor adapted to rotate a full revolution in response to each pulse applied to the stator is provided. Positioning magnets are provided for positioning a rotor in a rest position and a stator is positioned around the rotor to overcome the magnetic field of the positioning magnets upon the application of a pulse to the stator to thereby effect a complete revolution of the rotor.
