Abstract: An electric machine assembly includes a stator. The stator includes a core defining a rotational axis, windings assembled into the core, and a back iron heat exchanger mounted to the core, extending around the rotational axis. A plurality of coolant circuits pass from one or more coolant inlets in the back iron heat exchanger through the back iron heat exchanger, to one or more coolant outlets in the back iron heat exchanger. Between the one or more coolant inlets and the one or more coolant outlets, the plurality of cooling circuits are in fluid isolation from one another and from radially inner and outer surfaces of the back iron heat exchanger.

Abstract: A system includes a fuel cell stack. A heat exchanger has an air passage in thermal communication with an H2O passage for heat exchange between air and H2O. An exhaust outlet of the fuel cell stack is connected in fluid communication with an H2O inlet of the heat exchanger for supplying H2O to the heat exchanger.

Abstract: A system for cooling a cabin air compressor (CAC) motor includes a water separator which extracts water from airflow through a turbine and/or a fuel cell, and a CAC motor including cooling channels connected to an inlet and an outlet. The inlet of the CAC motor receives water from the water separator. The steam at the outlet of the CAC motor can be repurposed for warming utilities in an aircraft cabin, or for de-icing or increasing enthalpy of the turbine. The cooling water flow can be directed to the CAC motor in response to a predicted temperature of the CAC motor exceeding a threshold. The predicted temperature can be generated by feeding inputs including CAC motor input power measured by a power sensor, differential pressure measured by a pressure sensor, and a temperature at an air cooling inlet measured by a temperature sensor to a processor which generates a map model.

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: The present disclosure provides air cooling systems and methods for propulsion systems (e.g., aviation or aerospace propulsion systems). More particularly, the present disclosure provides integrated air cooling systems and methods utilizing air cycle machine cooling for hybrid-electric aircraft or aerospace propulsion systems or the like. The present disclosure provides integrated air cycle machine cooling into the hybrid propulsion system (e.g., into the wing-mounted hybrid propulsion system). As such, the air cooling systems and methods of the present disclosure can minimize weight while improving electric motor/generator cooling.
