Abstract
A stator core for rotary high power density electro-mechanical transducers formed of multiple segments which have a plurality of radially oriented teeth. The stator core is a composite of two or more segments circumferentially combined to form a cylindrical stator or armature for electric motors or generators. The segments are wound with wire either when the segments are aligned linearly, when arranged circumferentially on the inside surface of a jig or about a cylinder. The wound stator can have teeth extending radially outwardly or inwardly, to accommodate an outside or inside rotor.
