    Abstract: A stator assembly that includes a graphite sheet-like element that has fold(s) so as to define at least two planar sections. The face of one of the planar section abuts a surface of a heat generating location(s) of the stator assembly and a face of another planar section abuts one the tooth or the slot bottom of the stator assembly. Also, a subassembly that includes an electrical machine stator assembly that includes a sheet-like element of a material having high thermal conductivity, wherein a portion of the element abuts the end winding(s) such that the sheet-like element conducts heat to the magnetic core, the stator housing, and/or a winding heat conduction element.

    Abstract: At least one thermal module in fluidic communication with the one or more electronic components. The thermal module including a hydraulic motor operable to rotate a motor output shaft. The module further including a fan coupled to the motor output shaft, at least one heat exchanger in fluidic communication with the fan to provide passage therethrough of an air stream in response to rotational movement of the fan, and a conduit carrying a pressurized liquid stream through the hydraulic motor and each of the at least one heat exchanger. The pressurized liquid stream causing the motor output shaft to rotate and wherein heat in one of the air stream or the pressurized liquid stream is passed through each of the at least one heat exchanger and rejected into the other of the air stream or the pressurized liquid stream. A thermal management system including the at least one thermal module is disclosed.
