METHOD OF MANUFACTURING STATOR CORE, AND STATOR CORE

摘要

This embodiment comprises: a die-cutting process for die cutting, from a belt-formed magnetic steel sheet, iron core materials that are circular, have a plurality of slots on the inner circumference section thereof, and have m number of pieces, wherein m is an integer of 2 or more, of interconnecting lug sections protruding from the circular outer circumference sections thereof to the outer side in the diameter direction thereof; and a laminating process for laminating multiple pieces of the iron core materials. In the die-cutting process, portions of the belt-formed magnetic steel sheet that are to be die-cut are arranged side-by-side in n number of rows, wherein n is an integer of 2 or more, in the width direction of the belt-formed magnetic steel sheet, and at least one lug section among the lug sections of each of the iron core materials contained in one row among the n number of rows is positioned between iron core materials that are adjacent to each other in the longitudinal direction in a row adjacent to that one row.
