<p>A cooling liquid flow path (30) is extending in an axial direction inside a laminate stator core (14), and cooling liquid communication paths (32 and 34) are formed in front and rear housings (20, 22) clamping the laminate stator core (14) between them in such a manner as to dispose one continuous cooling liquid path in a motor (1). An exciter winding (16) wound on the laminate stator core (14) is covered with a heat transfer member (42) made of a heat conductive composite resin material. The heat conductive composite resin material is obtained by mixing a resin material having high heat resistance and moldability with an electrically insulating granular material having high heat conductivity such as aluminum oxide. The heat transfer member (42) is in thermal contact with the exciter winding (16), the inner wall surface of a slot of the laminate stator core (14), and the inner wall surfaces of the front housing (20) and the rear housing (22).</p> |
