In a dynamoelectric machine which includes a rotor and a stator, an integral magnetic isolation and cooling system. A housing is disposed about the machine, the housing being fabricated of magnetically permeable material to define a flux path therethrough. A cooling jacket is sandwiched between the housing and the stator. The cooling jacket has coolant passages therein and is fabricated of non-magnetic material to isolate the flux path between the housing and the stator.
