ABSTRACT:
Each pair of coils mutually connected in a stator winding is arranged in a fashion that a first coil of each pair of coils has an inner-circumferential-side coil terminal (212) led out from an inner-circumferential-side slot position in the direction of a coil end (220) of the stator winding, and that a second coil of each pair of coils has an outer-circumferential-side coil terminal (211) led out from an outer-circumferential-side slot position in the direction of the coil end (220) of the stator winding for connection to the inner-circumferential-side coil terminal (212), wherein there is provided a coil terminal connection structure in which the inner-circumferential-side coil terminal (212) is connected to the outer-circumferential-side coil terminal (211) across the coil end (220), and joint parts (211a,212a) thereof are bent close to the coil end (220).
