Step motor

In a step motor having a rotor magnetized to have a pair of magnetically opposed circumferentially spaced poles said rotor being adapted to rotate a complete revolution in response to each pulse applied to said motor, the improvement comprising magnetic positioning means adapted to produce a first flux field for magnetically positioning said rotor in a rest position, and two stator poles surrounding said rotor and defining a substantially uniform gap between said stator poles and said rotor, said stator pole portions in facing relationship defining a gap therebetween, said stator poles in response to a pulse applied thereto being adapted to produce a second flux field sufficient to overcome the flux field positioning said rotor in a rest position, said second flux field effecting a complete rotation of said rotor.
