Abstract: A thermal management includes an inductor, a housing in thermal communication with the inductor, the housing defining a wall, and a conductor. The conductor has a greater heat transfer rate than the wall and is positioned within a groove and/or an aperture formed in the wall. The conductor is configured to transfer heat through the wall more efficiently than if the conductor were not present. A method of manufacturing a thermal management system includes forming a housing by additive manufacturing. The housing defines a wall having at least one of a groove and an aperture defined therein. The method includes positioning a conductor in at least one of the groove and the aperture. The conductor has a greater heat transfer rate than the wall. The method includes positioning an inductor into thermal communication with the housing.

Abstract: A system comprises a stator core defining a plurality of winding slots between circumferentially spaced apart teeth. A respective cooling channel is defined within each of the circumferentially spaced apart teeth for circulation of coolant fluid through the stator core. The stator core is a laminated structure, where the teeth, winding slots, and cooling channels are part of a common laminated structure with the stator core.

Abstract: A power electronics cooling system includes a ram air fan with one or more blades and a ram air fan motor connected via an output shaft. The ram air fan draws in air and passes it across a heat exchanger to cool one or more cooling liquids. One or more pumps pressurize and pump the cooling liquids to various electronic components, including one or more motor controllers. The pumps may be mechanically or electrically coupled to the output shaft of the ram air fan, such that the motor of the ram air fan provides energy to the pumps.

Abstract: A wedge for a wound rotor includes a wedge body. The wedge body has a first layer and one or more second layers interfused with one another to provide structural support and limit resistive heating of the wedge from current flow within the wedge body by windings spaced apart by the rotor wedge. Generator rotors and methods of making generator rotors are also described.

Abstract: A transformer assembly includes a housing, a core within an interior of the housing, and at least one winding positioned around the core. The at least one winding and the core are mounted to the housing with potting material. At least a portion of a fluid circuit is defined within at least one wall of the housing. The at least the portion of the fluid circuit is defined through an opening in the at least one wall of the housing in fluid communication with the interior of the housing. A transformer assembly includes a housing, a core within an interior of the housing, at least one winding positioned around the core, and a fluid circuit defined at least partially within at least one wall of the housing being configured such that heat is transferred to the fluid from at least one of the core and the at least one winding.

Abstract: A phase leg for an inverter includes a switching module having a switch device, a power lead connected to the switching module and in electrical communication with the switch device, and a drive lead. The drive lead is connected to the switching module, is in electrical communication with the switch device, and is segregated from the power lead to limit heating of a drive module connected to the drive lead from current flowing through the power lead. Multilevel inverters and methods of making phase legs for inverters are also described.
