Abstract
A layer of highly conductive material is provided which forms a complete electrical path about the secondary of a linear motor, perpendicular to the face of the secondary. The layer comprises a section of highly conductive material attached to each face of the secondary communicating with a primary. In one embodiment, the layer completely encircles the secondary. In other embodiments, electrically conductive means join the sections of the layer, thereby creating the complete electrical path about the secondary.
