    Abstract: A rotating machine has a shaft rotatable about an axis, a rotor rotatable with the shaft, and a rotor end winding at an axial end of the rotor. A stator is spaced from the rotor and forms a gap therebetween. The stator comprises a stator winding. A fluid system directs fluid through to the stator. A baffle to diverts fluid away from the gap and toward the stator.

    Abstract: A liquid cooled generator is provided having a rotor having a central core and a main stator winding wrapped around the central core. A first laminate at a first end of the central core is provided having a first orifice defining a first diameter and a second laminate at a second end of the central core is provided having a second orifice defining a second diameter that is the same as the first diameter. A flow line passes through the central core and is configured to extend from the first laminate to the second laminate, the flow line defining a third diameter that is larger than the first and second diameters. The first and second diameters are configured such that air flow is permitted to pass through the first and second laminates and to restrict the flow of a liquid through the first and second laminates.

    Abstract: An assembly includes a first conductor, a tube extending along the first conductor between first and second ends of the first conductor, and an electrically-insulating barrier surrounding the first conductor and the tube such that the tube is spaced from the first conductor. Another assembly includes a plurality of conductors, a first tube extending along at least one of the conductors, and an electrically-insulating barrier enclosing the conductors and the first tube in which the barrier maintains spacing between the first tube and one or more adjacent conductors. In each assembly, the tube is configured to permit a fluid to flow therethrough. A method of manufacturing a feeder cable includes providing conductors that extend between first and second lugs of each conductor, enclosing the conductors within an electrically-insulating layer, and forming a cooling passage within the electrically-insulating layer that extends along one of the conductors.

    Abstract: A fully enclosed fan motor assembly includes a motor housing. A stator is located radially inward from the motor housing. A rotor is located radially inward from the stator, and the gap in between the rotor and stator defines a rotor stator gap. A shaft is located radially inward from the rotor. A fin portion extending radially outward from the shaft is used to dissipate heat from the rotor to air drawn through the rotor stator gap and over the fin portion.

    Abstract: A ram fan device includes a motor disposed in a housing that defines a motor cavity with a fan operatively connected to be driven by the motor and an outlet in fluid communication with the motor cavity. The housing includes a cooling inlet therethrough downstream of the fan and upstream of the motor, the cooling inlet being in fluid communication with the outlet through the motor cavity such that airflow can pass through the cooling inlet through the motor cavity and out the outlet.
