1. A motor comprising:
a rotor; and a stator opposed to the rotor with a radial gap or an axial gap formed therebetween, the stator including a plurality of pole cores and a stator coil comprised of a plurality of unit coils each of which is concentratedly wound around a corresponding one of the pole cores, wherein each of the unit coils is comprised of a pair of first and second sub-coils that are stacked in two layers in a stacking direction, the stacking direction coinciding with a height direction of the corresponding pole core, each of the first and second sub-coils is spirally wound so that coil sides of the sub-coil overlap each other in an overlapping direction perpendicular to the stacking direction, each of the unit coils also has, at a single place, a connecting portion that connects the first and second sub-coils of the unit coil, the connecting portion is provided in a coil end of the unit coil, and for each of the first and second sub-coils of the unit coil, the connecting portion is located at an innermost periphery of the sub-coil in the overlapping direction of the sub-coil. |
