ROTATING ELECTRIC MACHINE STATOR AND ROTATING ELECTRIC MACHINE STATOR MANUFACTURING METHOD

A stator for a rotating electrical machine is disclosed that includes a stator core and a stator coil of a plurality of phases. The stator coil of the plurality of phases is formed by winding a plurality of double-wound coils of each phase around the stator core along an entire circumference of the stator core. Each of the plurality of double-wound coils concentrically include a coil portion with a larger circumference length and a coil portion with a shorter circumference length. The double-wound coil of each phase includes a first double-wound coil farthest from a neutral point and a second double-wound coil other than the first double-wound coil. Of the first double-wound coils of first to third phases, only the combination of the first double-wound coils of the first and second phase overlaps in a specific circumferential section corresponding to at least one slot, and the first double-wound coils of different phases are inserted in different slots.
