Abstract: A rotating electric machine includes a field element having a plurality of magnetic poles of which polarities alternate in a circumferential direction, and an armature including an armature winding of multiple phases and an armature core having a circular cylindrical shape. The armature core is provided integrally with the armature winding. The field element and the armature are provided to oppose each other in a radial direction. An armature holding member includes a circular cylindrical portion assembled on an inner side in the radial direction of the armature core. The armature core and the circular cylindrical portion are fitted and fixed to each other with a predetermined tightening margin. A regulating portion regulates displacement in the circumferential direction of the armature core by engagement in the circumferential direction, and is provided in portions of the armature core and the circular cylindrical portion that oppose each other in the radial direction.

Abstract: A rotating electric machine includes an armature coil having a plurality of phase windings for respective phases. Each of the phase windings is constituted of a plurality of partial windings each having a pair of intermediate conductor portions and a pair of bridging portions connecting the pair of intermediate conductor portions. All the intermediate conductor portions of the partial windings are arranged in a predetermined sequence in a circumferential direction. At each of coil ends of the armature coil, the bridging portions of the partial windings of different phases intersect one another. Each of the partial windings has a mounting member provided integrally therewith for mounting it to a support member. For each circumferentially-adjacent pair of the partial windings whose bridging portions intersect one another, the mounting members provided respectively integrally with the pair of the partial windings are together fixed to the support member by a common fixing member.
