Abstract: A method of manufacturing a laminated core includes supplying a stator material to a punching device and obtaining an electromagnetic steel plate corresponding to a rectangular processed body by punching the stator material. To obtain the electromagnetic steel plate ES, a slit is formed outside a processed body forming area in the stator material along a long side of the processed body forming area, and a center portion of the processed body forming area is punched out in a circular shape. Additionally, the processed body forming area is punched out after the slit is formed and the center portion is punched out. The laminated core is obtained by laminating and fastening a plurality of the electromagnetic steel plates.

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.
