Abstract
A stator includes a stator core and a stator coil formed of electric conductor segments. Each of the electric conductor segments has a pair of in-slot portions, a first end portion, and a pair of second end portions. The in-slot portions are respectively received in corresponding two slots of the stator core. The first end portion extends, on one axial side of the stator core, to connect the in-slot portions. The second end portions extend respectively from the in-slot portions on the other axial side of the stator core. Each of the second end portions includes an oblique part and a distal part. The oblique part extends obliquely with respect to an axial end face of the stator core. Corresponding pairs of the distal parts of the electric conductor segments are joined by welding. The oblique parts of the electric conductor segments have a higher hardness than the in-slot portions.
