Abstract: A dual-face, internally-mounted cooling fan is provided in a dynamoelectric machine, e.g. an alternating current generator. The generator includes a ventilated housing supporting a stator assembly and a rotor assembly. The fan includes a divider disk having a plurality of blades provided on each surface and is mounted to rotate with the rotor assembly. As the fan is rotated, a plurality of separate air currents are drawn axially into the housing for cooling. The divider disk prohibits substantial mixing of currents drawn from opposite ends before they are radially expelled from the housing.

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.

Abstract: An end frame and stator assembly for a dynamoelectric machine such as an alternating current generator. The assembly comprises a slotted stator core that supports a stator winding, a rotor bearing and a metallic heat dissipating insert that supports the bearing. The assembly has a plastic housing that is comprised of plastic material that is molded to the stator core and insert. The plastic housing does not encapsulate the stator winding. The metallic insert conducts heat away from the bearing and also adds stability to the plastic housing.
