Abstract

A stator assembly for an alternating current generator. The stator core is a one-piece molded part that is formed of iron powder having a particle size in a range of about 10 to 250 microns. The powder is bound together by a thermoplastic material which covers the particles and which serves to insulate the particles from each other. The particles may be coated with phosphorus and the phosphorus layer overcoated with the thermoplastic material. A three-phase output stator winding is carried by the core and has conductor portions located in core slots.
