Claims

[Claims for Utility Model Registration] 1. A protruding piece and a cut-out piece formed by bending a part of the core are provided at a common location of each fan-shaped segmented core that is stacked with their ends aligned, and the protruding piece of each segmented core is It is press-fitted into the cutout hole of another split core to be overlapped to form a plurality of stacked and fixed split stacked cores, and the ends of these split stacked cores are connected in the circumferential direction to form a ring shape. A stator core for a rotating electrical machine, characterized in that a core portion of the rotary electric machine is formed. 2. An engaging protrusion is provided at one end of each of the divided cores, and an engaging recess corresponding to the engaging protrusion is provided at the other end, and each divided laminated core is laminated and fixed so that each divided laminated core is engaged with the engaging protrusion. A stator core for a rotating electric machine according to claim 1, which is connected in a ring shape by engaging with a mating recess.
