Abstract

See full text

A method for manufacturing a laminated iron core includes providing a plurality of annular iron core piece rows, each of which is configured by annularly arranging a plurality of divided iron core pieces including yokes and teeth, and the yokes of the annularly-adjacent divided iron core pieces in the annular iron core piece row are mutually different in shape. In the method, the annular iron core piece rows are laminated by changing a rotational angle of the newly laminated annular iron core piece row relatively to the lastly laminated annular iron core piece row laminated so that the divided iron core piece with a shape different from that of the divided iron core piece is laminated on the lastly laminated divided iron core piece.
