Abstract:
A rotary electric machine includes: a rotor; and a stator including: a stator core; and an armature winding that is mounted to the stator core. The armature winding includes by a plurality of identical-phase winding portions in which identical-phase coil portions among coil portions in which conducting wires are wound in concentration onto respective teeth are connected together into a series circuit by crossover wires, and that also have lead wires at two end portions. Each of the lead wires of each of the identical-phase winding portions is led out in a first axial direction of the rotor from coil portions that have identical phase, that are disposed to be adjacent in a circumferential direction of the stator core; and all of the crossover wires of each of the identical-phase winding portions are led out in a second axial direction of the rotor.
