Abstract: Aircraft electric motors are described. The aircraft electric motors include a cooling system comprising an annular heat exchanger, a motor housing arranged radially inward from the heat exchanger, the motor housing defining a rotor-stator cavity and a gear assembly cavity, a rotor sleeve arranged within the rotor-stator cavity, a gear assembly arranged within the gear assembly cavity, a first shaft operably coupled to the rotor sleeve and configured to be rotationally driven by the rotor sleeve to drive rotation of a portion of the gear assembly, and a second shaft operably coupled to the gear assembly and configured to be rotationally driven by the gear assembly.

Abstract: Disclosed is an assembly including a busbar that includes: a first layer that defines: first layer top and bottom surfaces; first layer first and second ends; and a first layer center region between the first layer first and second ends; and the first layer forms first layer perforations of different sizes about the first layer center region so perforations closer to the first layer first end are smaller than perforations spaced apart therefrom; a second layer that is disposed against and electrically isolated from the first layer bottom surface, wherein the second layer defines connector orifices having a same size as each other that are aligned with the first layer perforations; and a first capacitor supported against and electrically connected to the first layer top surface, wherein the first capacitor includes busbar connectors that respectively extend through the first layer perforations to electrically connect with the connector orifices.

Abstract: An electronics assembly includes a motor controller electronics arrangement with a solid-state switch array, a feeder cable connected to the motor controller and in electrical communication with the solid-state switch array, and a phase change material body. The phase change material body is thermally coupled to the feeder cable and arranged outside of the motor controller to limit conduction of heat generated by resistive heating of the feeder cable into the motor controller and through the feeder cable. Vehicles, electrical systems, and methods of cooling feeder cables in motor controller electronics arrangements are also described.

Abstract: An electronics assembly including a motor controller electronics arrangement includes a housing enclosing a solid-state switch array, a cold plate arranged within the housing and in thermal communication with the solid-state switch array, and a feeder cable. The feeder cable is electrically connected to the solid-state switch array, has a coolant jacket extending thereabout, is separated from the switch arrangement by the housing, and is in liquid communication with the cold plate to limit heat communicated by the feeder cable into the housing. Electrical systems and methods of cooling feeder cables are also described.
