Abstract: An aircraft system includes a housing having an outer surface and an inner surface defining a cavity. A motor is arranged in the cavity. The motor includes a heat producing component mounted to the inner surface. A first cooling system is configured to direct a first heat exchange fluid in a first thermal exchange relationship with the heat producing component and a second cooling system is configured to direct a second heat exchange fluid in a second thermal exchange relationship with the heat producing component. The second heat exchange fluid is distinct from the first heat exchange fluid and the second thermal exchange relationship is distinct from the first thermal exchange relationship.
