ABSTRACT:
In a preferred embodiment, an oscillating stepping motor having only one stator phase. What would otherwise be a second stator phase is a magnet fixedly disposed with respect to the rotor to produce a detent position of the rotor. When the stator is energized, the field of the fixed magnet is at least partially overcome and the rotor steps to a first predetermined position. When the stator is de-energized, the rotor returns to the detent position. Alternately energizing and de-energizing the stator causes the rotor to oscillate between the two positions. Alternatively, an angle of oscillation twice that produced above may be provided by reversing the stator field to oscillate the rotor between the first predetermined position and a second predetermined position produced by reversing the stator field.
