An electric rotating machine includes a rotor and a stator. The rotor has a plurality of pairs of magnetic poles. The stator includes a stator core and a stator coil that is comprised of a plurality of phase windings wound on the stator core. The stator core has, for each of the phase windings of the stator coil, n circumferentially-consecutive single-phase slots, in which only the phase winding is received, per magnetic pole of the rotor, where n is a natural number not less than 2. Each of the phase windings of the stator coil has first to kth sections that are sequentially arranged from one end to the other end of the phase winding, where k is a natural number not less than 2. The first section is received in different ones of the single-phase slots for the phase winding from the kth section. |

1. An electric rotating machine comprising:
a rotor having a plurality of pairs of magnetic poles that are arranged in a circumferential direction of the rotor; and a stator including a stator core and a stator coil, the stator core having a plurality of slots, which are arranged in a circumferential direction of the stator core, and being radially opposed to the rotor, the stator coil being comprised of a plurality of phase windings each of which is wound on the stator core so as to be inserted in corresponding ones of the slots of the stator core, wherein the stator core has, for each of the phase windings of the stator coil, n circumferentially-consecutive single-phase slots, in which only the phase winding is received, per magnetic pole of the rotor, where n is a natural number greater than or equal to 2, each of the phase windings of the stator coil is comprised of j sub-windings that are connected in parallel with each other between opposite ends of the phase winding, where j is a natural number greater than or equal to 2, each of the sub-windings includes k sections that are sequentially arranged from one end of the sub-winding to the other end of the sub-winding, where k is a natural number greater than or equal to 2, and the first to the (k/2)th sections are received in different ones of the single-phase slots for the phase winding from the (k/2+1)th to the kth sections. |
