Abstract:
Provided is a method for manufacturing a core piece that enables manufacturing of a core piece or a member belonging to a core piece that is sufficiently flat for practical use. This method for manufacturing a core piece, wherein core pieces are manufactured by punching a plurality of members from a single sheet of a material 1, has: a lancing step wherein a boundary line 4 is formed between one stator core piece 2a and another stator core piece 2b adjacent to the stator core piece 2a; and a reverse bending step wherein, after the lancing step, the stator core piece 2b is bent in the direction opposite the direction in which it was bent in the lancing step, thereby providing a bend in the reverse direction in the stator core piece 2b.
