<p>A motor for providing reciprocating motion comprises a stator defining an arcuate pole face and a flat pole face and an armature defining a complimentary arcuate pole face and flat pole face, where the armature rotates about a pivot point in order to maintain a fixed air gap between the arcuate pole faces of the stator and the armature and a variable air gap between the flat pole faces of the stator and the armature.</p> |
