STATOR, STATOR CORE FOR STATOR, STATOR CORE PRODUCTION METHOD, AND SHEET CORE BENDING DEVICE

摘要

A first end section (202) and a second end section (203) in a stator core (20) face in the circumferential direction when the stator core (20) forms a ring shape and have: a pair of mutually meshing sections comprising a coupling recessed section (31) and a coupling protruding section (32); and a pair of guiding sections comprising a guiding protruding section (36) and a guiding recessed section (37) that guide so as to position the radial position when the end sections (202, 203) couple prior to the meshing of the coupling recessed section (31) and the coupling protruding section (32). As a result, the coupling recessed section (31) and the coupling protruding section (32) are coupled in a state of having been positioned by the guiding protruding section (36) and the guiding recessed section (37). Therefore the receipt of large stress is avoided until the coupling of the coupling recessed section (31) and the coupling protruding section (32) has been completed. Accordingly, deformation of the coupling section can be prevented, and the deterioration in magnetic properties can be suppressed.
