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.
Claims9
An annular stator for a rotary electro-mechanical transducer comprising:
- a plurality of segments, at least some of said segments being identical,
- individual ones of said segments comprising an axially elongated body having a radical outer portion and radial inner teeth portions, said radial outer portion having an axially extending side surface;
- said radial outer portion being circumferentially wider than said radial inner teeth portions so that when said plurality of said segments are assembled in an annular configuration a plurality of slots are defined between said radial inner teeth portions and a return path is defined by direct contact between an axially extending side surface of a first segment and an axially extending side surface of a second segment adjacent to said first segment.
