Abstract
Disclosed power systems include an engine configured to output mechanical power via a shaft and a generator coupled to the shaft. The generator includes a rotor assembly and a stator assembly. The rotor assembly includes a rotor winding, a rotor core coupled to the shaft and mechanically supporting the rotor windings with respect to the shaft, an insulating shell between the rotor core and the rotor winding, and a plurality of fan blades extending from an axial end face of the rotor core. The fan blades are configured to generate an airflow proximate the rotor assembly while the rotor assembly is being rotated by the shaft.
