Abstract
This invention prevents leakage of cooling medium from a cooling passage in the interior section of a slot of a stator. Coils are housed in the slot of the stator core. The openings of the slot are covered in order to form a cooling passage in the slot. An end plate is disposed on the end of the stator. The stator core and the end plate are integrated by winding coils through the outer side of the end plate. A cylindrical member which projects along the inner peripheral face of the stator from the end of the stator is formed by resin molding to be integrated with a section of the end plate. A ring-shaped space which introduces cooling medium is formed on an outer peripheral side of the cylindrical member and is connected with the cooling passage.
