Abstract
Linear electric generators include stationary windings and armature magnets arranged to reciprocate axially relative to the windings, or stationary magnet structures and movable windings arranged to reciprocate relative to the stationary magnet structures. The armature magnets or stationary magnet structures are in the form of multiple pole magnets made up of a plurality of individual pole structures, each pole structure including a pair of magnets joined to each other with facing poles of like polarity. In addition, the windings may be in the form of a double winding structure including at least one first clockwise winding and at least one second counterclockwise winding arranged in a multi-layered stacked arrangement.
