ABSTRACT:
The laminated core structure of a motor includes a stator iron core formed by laminating a plurality of stator iron core thin sheets in which a plurality of magnetic poles are provided at fixed intervals along the circumferential direction on the inner peripheral side so as to project toward the center direction, and a rotor iron core arranged on the axis line of the stator iron core concentrically with the stator iron core and formed by laminating a plurality of disc-shaped rotor iron core thin sheets, the stator iron core and the rotor iron core each being fastened by caulking the plurality of thin sheets to each other. The core loss produced by caulking is decreased by particular placement of the center of a caulking uneven part of the stator iron core thin sheet and the center of a caulking uneven part of the rotor iron core thin sheet.
