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 m1, m2 and m3, respectively a relationship of 0<2×m2/(m1+m3) is satisfied.

Abstract: Reduction in drive torque of a permanent magnet motor having a skew arrangement is to be suppressed. A permanent magnet motor has a rotor including a rotor core formed as a stacked assembly of a plurality of electromagnetic steel sheets stacked one upon another and magnets accommodated within accommodation holes formed inside the rotor core. The rotor core has a skew arrangement including a first core and a second core that are displaced relative to each other in a circumferential direction relative to an axis of the rotor. The accommodation hole of the first core accommodates a first magnet of the magnets. The accommodation hole of the second core accommodates a second magnet of the magnets. The first magnet and the second magnet are opposed to each other via a first gap therebetween in the direction of the axis.
