Abstract
A fluid cooled electrically assisted turbocharger (1) comprising a housing (3) and an electric motor suitor (22) disposed in the housing (3). The stator (22) includes a pair of o-rings (204, 208), or other circumferential seals, disposed therearound. The circumferential seals (204, 208) may be disposed in corresponding grooves (202, 206) formed into the circumference of the stator (22). The o-rings (204, 208) are operative to seal against an interior (142, 144) 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).
