Abstract:
A motor includes a stator that has pole cores and a stator coil comprised of unit coils each being concentratedly wound around a corresponding one of the pole cores. Each of the unit coils is comprised of first and second sub-coils that are stacked in two layers in a stacking direction. 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. 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.
