PROBLEM TO BE SOLVED: To obtain a rotary electric machine in which occurrence of torque pulsation can be suppressed by regulating the radial position of adjoining iron core blocks each other, thereby enhancing the circularity of the inner diameter surface of teeth of armature cores assembled annularly.SOLUTION: An armature core 11 is configured by arranging a plurality of core blocks 12, each having an arcuate core back 12a and a teeth 12b extended radially inward from the inner peripheral wall surface of the core back 12a, annularly while butting the side faces of the core backs 12a in the circumferential direction. A fitting part of a fitting protrusion 15 and a fitting recess 16 is formed at the butting part of the side faces of the core backs 12a in the circumferential direction, thus regulating radial position of the core blocks 12 adjoining in the circumferential direction. |
