| Zusammenfassung: | A rotating electrical machine can increase the strength of divided cores and, in addition, can achieve both a reduction in iron loss and a high rigidity of the divided cores. The stator of the rotating electrical machine includes a stator core having radially divided cores arranged in a ring, each divided core being a laminate of magnetic steel sheets. Each divided core has a swaged portion in which the laminated magnetic steel sheets are bonded by swaging. The swaged portion is disposed in a core back portion, which is in contact with core back portions of divided cores located on both sides of the divided core at a position whose distance from an outer periphery of the core back portion is within ⅓ of a radial length of the core back portion. |
