Abstract:
An electric motor including:a magnetic field means for producing a magnetic field having lines of flux extending in a first direction;a support capable of at least two dimensional motion in a plane relative to the magnetic field means and provided with a minimum of two electrically conductive paths, each path having a segment that extends through the magnetic field in a second direction so that interaction of an electric current flowing through a particular segment and the magnetic field produces a thrust force acting on the support via that segment;a first one of said segments located relative to a second one of said segments so that their respective thrust forces do not lie on the same axis; wherein the direction and magnitude of the respective thrust forces and thus the motion of the support relative to the magnetic field means can be controlled by varying the magnitude and/or phase relationship of electric currents flowing through the segments.
