MANUFACTURE OF STATOR FOR ROTOR AND STATOR FOR MOTOR

PROBLEM TO BE SOLVED: To provide a manufacturing method for a stator for a motor, the assembling operability of which is good and to provide the stator for the motor. SOLUTION: A yoke core 110 is formed, in such a way that ring-shaped yoke core pieces which are punched and worked by a press mold are laminated, tightened and connected. A core 120 is formed in such a way that core pieces which are punched and worked by a press mold and which comprise N pieces of magnetic pole parts are laminated, tightened and connected. The yoke core 110 and the core 120 forms a stator in which protruding parts 122 for coupling, formed on the core 120 are fitted and bonded to recessed parts 112 for coupling, formed on the yoke core 110. The dimension of N pieces of the protruding parts 122A,...122I for coupling, which are formed on the core pirces is formed so as to become successively large in the circumferential direction. In addition, the dimension of N pieces of the recessed parts 112A,...112I for coupling, which are formed on the yoke core pieces is formed so as to become successively large in the circumferential direction.
