Abstract: There is provided a method for producing a rotor laminated core by laminating circular core pieces. The method determines a first blanking area, a second blanking area and a third blanking area in the magnetic steel board, wherein the first blanking area defines a shape of the core piece, the second blanking area defines a shape of a magnet-insertion hole, and the third blanking area defines a shape of an arbitrary part in the magnetic steel board. The method also forms a temporary aperture in the second blanking area, forms a thinning part which extends from the temporary aperture to the third blanking area, and blanks the first blanking area, the second blanking area and the third blanking area, thereby producing each circular core piece including the thinning part and magnet-insertion holes formed in a circumferential direction.
