Abstract
A rotating electric machine includes: a stator having slots in which coils formed of conductive wires are stored; and a rotor facing the stator and having magnetic poles. The rotating electric machine has a fraction slot configuration or an integer slot configuration. The coils configure a mixed phase band group in which a first, second and third basic phase band groups are stacked in this order in a radial direction of the slots. In the mixed phase band group, a magnitude of magnetomotive force of each phase per pole is uniform, and, when the number of layers of the first, second and third basic phase band groups in the radial direction are denoted by m, mand m, respectively a relationship of 0<2×m/(m+m) is satisfied.
