ABSTRACT:
A differential displacement electromagnetic device providing motion over a support frame. Permanent electromagnets are fixedly mounted to a carriage and angularly oriented relative to the support frame lengthwise axis. Upright anchor columns project transversely from the support frame, and are interconnected by tension springs. A movable block is slidingly carried over both rails including a pair of opposite side spring loaded arms, carrying floating electromagnets. A bracket mount carries two spaced pivotal axles, and pivotally mounted rocker arms carrying corresponding permanent magnet. The rocker arms are sized in such a way as to be pivotably movable between a first limit position, where the permanent magnets abut against the angularly oriented electromagnets, and a second limit position, where the permanent magnets abut against the floating electromagnets.
