Summary:PROBLEM TO BE SOLVED: To radiate heat generated from a stator winding 3 efficiently to the outside in a cooled housing rotary electric machine by improving heat transmission between the outer circumferential surface 1a of a stator core 1 and the inner wall portion 2a of a stator frame 2. SOLUTION: A stator 4 is formed on the inside of a stator frame 2 by arranging a stator core 1 with a stator winding 3 mounted thereon, heat generated from the stator winding 3 is radiated from the housing of the stator 4 through the stator core 1 or the stator frame 2, and the housing of the stator 4 is brought into contact with cooling medium and cooled. A thermally conductive member layer 14 excellent in flexibility is provided in the gap 13 between the outer circumferential surface 1a of the stator core 1 with the stator winding 3 mounted thereon and the inner wall portion 2a of the stator frame 2. The thermally conductive member layer 14 is formed by laminating graphite sheets or injecting a material having fluidity. COPYRIGHT: (C)2007,JPO&INPIT
