Abstract
Abstract There is disclosed herein an electrical generator which includes a linear reciprocating armature mechanically coupled with a source of relative motion. The armature comprises a plurality of magnet means defining north-south poles in alternately opposite directions, the axis of the poles being orthogonal to the direction of reciprocation of the armature. Each of said pole magnets is mounted parallel at relative distances to each other that are equal to their widths in the direction of armature reciprocation. Further provided in the generator is a stator including a plurality of groups of continuous windings, each group corresponding to an adjacent pair of magnet means, each group wound parallel to a plane defined by the direction of reciprocation of the armature and the center point of the axis of the poles of the magnet means. Each winding has a width equal to the width of each pole of the magnet means in the direction of armature reciprocation. Also, each winding group is separated from the adjoining group by a width equal to the pole of each magnet. There is further provided means for limiting the advance and reverse of the armature to a distance equal to three times the width of each pole of each magnet. Also furnished is a housing that will place the stator as close to the armature as possible in order to minimize the air gap therebetween.
