Abstract
A linear actuator powered by a Lorentz force. The force is generated by passing an electrical current through an armature spanning a space across a magnetic field established between two permanent magnets. The armature is mounted upon a slider extending between a pair of electrically conductive rails. Reversible linear motion is achieved by switching the polarity of an electrical potential applied across the two rails.
