減を図ることが可能となる。As described in detail above, the method for manufacturing a stator core according to the present invention comprises a step of punching and forming a stator core piece from a belt-shaped material using a progressive die apparatus.
A laminating step of sequentially laminating a predetermined number of stator core pieces subsequent to the outer diameter removing step to integrate them, and a slit for separating the stator core pieces into a predetermined number of divided iron core pieces before the outer diameter removing step. And a slitting step of forming the material into a strip-shaped material. According to the above configuration, the stator core is manufactured in a state in which a plurality of divided cores are assembled together. The split iron cores can be assembled accurately and easily with each other, so that it is possible to prevent the deterioration of the electrical characteristics and the like due to the "shift" between the split iron cores. Also,
According to the above configuration, a plurality of divided iron cores constituting the stator core are manufactured at the same time, so that the time involved in manufacturing one stator core is reduced as much as possible, thereby reducing the manufacturing cost. Can be achieved.
