A laminated core structure of a motor is provided to suppress core loss due to calking by locating a calking position at the furthest position from a magnetic path as possible. A laminated core structure of a motor(1) includes a stator core(4) and rotor cores(9a,9b). The stator core is provided between a motor flange(2) and a bracket(3) forming a motor case(5). A rotor(6) is provided in the motor case. The rotor is composed of a magnet(8), and the rotor cores. Both sides of the magnet are supported on the rotor cores. The rotor is rotatably supported on an output shaft(7) through bearings(10a,10b) installed in the bracket and the motor flange, respectively. The rotor is concentrically arranged on a shaft line of the stator core.
