Abstract

Embodiments of the present invention provide a frictionless linear switched reluctance propulsion system. The propulsion system generates both a propulsive force for moving a load linearly, and a normal force for lifting the load. The normal force acts in a direction substantially perpendicular to a direction of the propulsive force.
