Beschreibung
Zusammenfassung:	An electrically assisted turbocharger (1) comprising a housing (3) and an electric motor stator (22) disposed in the housing (3). The stator (22) includes a pair of o rings or other circumferential seals (204 208) disposed therearound. The o rings (204 208) are operative to seal against an interior of the housing (3) to form an annular chamber (130) around at least a portion of the stator (22) and a pair of end cavities (122 126) at the axial ends of the stator (22). The annular chamber (130) is adapted to allow the circulation of a cooling fluid around the stator (22). A pair of bearings (10 12) may be disposed in the housing (3) one on each side of the stator (22). A shaft (7) is supported in the housing (3) by the bearings (10 12). The shaft (7) in tum supports a turbine wheel (5) and a compressor wheel. An electric motor rotor (24) is disposed on the shaft (7) between the bearings (10 12) and inside the stator (22).
