An induction motor includes a stator defining stator inner and outer diameters extending about a longitudinal axis, the stator includes a plurality of windings extending longitudinally and circumferentially between the stator inner diameter and the stator outer diameter and passing an electric current therethrough to create a magnetic field, a rotor extending along the longitudinal axis having a rotor outer diameter less than the stator inner diameter, the rotor rotates about the longitudinal axis relative to the stator in response to the magnetic field, and a stator thermal exchanging fluid circuit extending both through and about the stator whereby the stator thermal exchanging circuit exchanges thermal energy with the stator.
