An electrically assisted turbocharger () comprising a housing () and an electric motor stator () disposed in the housing (). The stator () includes a pair of o-rings, or other circumferential seals (), disposed therearound. The o-rings () are operative to seal against an interior of the housing () to form an annular chamber () around at least a portion of the stator () and a pair of end cavities () at the axial ends of the stator (). The annular chamber () is adapted to allow the circulation of a cooling fluid around the stator (). A pair of bearings () may be disposed in the housing (), one on each side of the stator (). A shaft () is supported in the housing () by the bearings (). The shaft () in turn supports a turbine wheel () and a compressor wheel. An electric motor rotor () is disposed on the shaft () between the bearings () and inside the stator ().
