PROBLEM TO BE SOLVED: To provide a stator for a motor which can be cooled effectively and besides can be manufactured easily. SOLUTION: A stator body 10 is manufactured by molding dust core material. A groove (for example, a spiral groove) is made at the peripheral face of the stator body 10, and it is accommodated in a lower casing 20 and is used as a refrigerant passage. Then, a refrigerant such as water or the like flows in the refrigerant passage via pipes 24 and 26. COPYRIGHT: (C)2007,JPO&INPIT
