ABSTRACT:
A laminated coil which may be used as a winding in electrical machinery is formed by multiple layers of thin electrically conductive material, each having an insulating layer on one side and being shaped in a specialized pattern. The patterns each form a winding and are shaped such that current flow therethrough generates a magnetic pole at only three of four cross-sectional sides. The laminated coil is formed of layers of these patterns arranged to provide a magnetic pole at all four sides.
