Beschreibung
Zusammenfassung:	A motor stator (24) has a stator iron core (24a), a stator winding (24b), and a mold member (30) embedding them in an inner portion and having a high coefficient of thermal conductivity. The mold member (30) has a heat insulating layer (32) closely attached to an inner surface thereof surrounding a motor rotor (22) and to an outer surface thereof in an axial direction. Further, an outer sleeve (26) is provided so as to be closely attached to an outer peripheral surface of the mold member (30) and to an inner surface of a bearing housing (16). The outer sleeve (26) forms a liquid tight water cooling jacket (26b) between the outer sleeve and the bearing housing.
