Abstract
A method for manufacturing a laminated iron core includes setting a blanking position on a strip-shaped workpiece for iron core pieces each including a yoke piece part having a linear shape and a magnetic pole piece part extending from the yoke piece part, such that a pair of iron core pieces are opposed each other and the magnetic pole piece part of one iron core piece is arranged between adjacent magnetic pole piece parts of the other iron core piece among the pair of iron core pieces, simultaneously blanking a front end side of the magnetic pole piece part and a back surface side of the yoke piece part of the one iron core piece from the strip-shaped workpiece before simultaneously blanking those of the other iron core piece from the strip-shaped workpiece, and blanking the iron core pieces from the strip-shaped workpiece.
