Abstract
An eccentric motion motor includes a hollow cylindrical stator in which is positioned a cylindrical armature in rolling engagement with the stator. Elongate conductive strips are disposed in the inside wall of the hollow of the stator to extend substantially the length thereof, with the strips being circumferentially spaced about the stator hollow. The conductive strips are coupled to a commutator voltage source which applies a voltage to successive ones of the conductive strips to produce an electrostatic force which attracts the armature and causes it to roll in the hollow of the stator. The armature may be made either of a conductive material or a dielectric material.
