摘要： An embodiment of an electric motor assembly includes a stator assembly extending generally along the longitudinal axis and at least partially enclosing a rotor assembly also extending along the longitudinal axis. The rotor assembly includes a rotating portion and one or more sets of rotor windings. The stator assembly includes a stationary housing having at least an inner wall and an outer wall, and one or more sets of stator windings in electromagnetic communication with the one or more sets of rotor windings. A heat exchanger is integrally formed into the housing, and includes a plurality of dividing walls extending between the inner and outer housing walls. The plurality of dividing walls are arranged at least partially circumferentially around the longitudinal axis to define, with the inner and outer walls, a corresponding plurality of integral heat exchanger channels arranged at least partially circumferentially around the one or more sets of stator windings. A plurality of rib turbulators are disposed on at least a channel-facing surface of the inner wall.
