PROBLEM TO BE SOLVED: To improve the heat-removal performance of a stator coil without increasing manufacturing cost.SOLUTION: A hollow member of hollow construction capable of charging refrigerant into its inside is disposed on an end face in the rotation axial direction of a stator with a coil. In molding a coil end in the rotation axial direction of the coil with resin, resin molding is performed to communicate with the outside of resin in which both ends of the hollow member are molded. |
