Abstract: A stator includes a stator core having slots arranged in a circumferential direction and a stator coil formed by wave-winding continuous coil wires on the stator core. Each of the continuous coil wires has in-slot portions received in the slots and turn portions each of which connects, on the outside of the slots, one pair of the in-slot portions. The stator coil is formed, by spirally rolling a band-shaped coil wire bundle that is formed by bundling the continuous coil wires, into a cylindrical shape. In the coil wire bundle, the continuous coil wires are transposed at a plurality of locations. Moreover, in a range where the continuous coil wires extend in the circumferential direction of the stator core by one complete turn, at least one interval between adjacent transposition locations in the coil wire bundle is greater than or equal to the circumferential length of one turn portion.

Each of the continuous coil wires has in-slot portions received in the slots and turn portions each of which connects, on the outside of the slots, one pair of the in-slot portions. Each of the continuous coil wires has, at root parts of the turn portions respectively connected with ends of the in-slot portions, first crank portions that are radially bent. An amount of radial bending of the first crank portions is set to be half of a radial width of the in-slot portions.

Abstract: An armature for a rotating electric machine includes an armature core and an armature coil. The armature core includes a substantially annular main body disposed in radial opposition to a field of the machine and teeth extending from the main body radially toward the field. The armature coil is arranged between the teeth of the armature core. For each of the teeth, there are formed a protrusion and a pair of claws at a distal end of the tooth. The protrusion protrudes from a circumferentially central part of the distal end of the tooth radially toward the field. The claws extend, respectively on opposite circumferential sides of the protrusion, from the distal end of the tooth toward the field. Each of the claws has a smaller width at its distal end than at its proximal end and is arcuate-shaped so as to engage with and thereby retain the armature coil.
Abstract translation: 用于旋转电机的电枢包括电枢铁芯和电枢线圈。 电枢铁心包括一个基本上环形的主体，其设置成与机器的磁场成径向地相对设置，并且从主体径向向外延伸。 电枢线圈设置在电枢铁芯的齿之间。 对于每个齿，在齿的远端形成有突起和一对爪。 突起从齿的远端的周向中心部径向朝向场突出。 所述爪分别在所述突起的相对的圆周侧上从所述齿的远端朝向所述场延伸。 每个爪在其远端具有比在其近端处更小的宽度，并且是弓形的，以便与电枢线圈接合并由此保持电枢线圈。
