Abstract

PURPOSE:To obtain a laminated core in high accuracy by forming a waveform of a depth responsive to the deviation in the thickness of a laminated core piece at a thin part to a reference part, thereby making the effective thickness uniform and eliminating the correction of the thickness at the laminating time. CONSTITUTION:When a laminated core piece 9 is punched from a strip core material 1, a waveform of a depth responsive to the deviation in the thickness is formed at least at the thin part, the effective thickness of the piece 9 is uniformalized, and the pieces are laminated to produce a laminated core 10. In this manner, the correction of the deviation in the thickness can be eliminated at the laminating time, and a laminated core can be accurately produced simply.
