摘要： In order to provide a rotary electric machine with a reduced size and improved weldability, the stator (10) of a rotary electric machine (M) has a segment coil (SC) formed by bending rectangular conductors (D), and a stator core (20) having slots (12) in which the segment coil (SC) is inserted. As for the weld parts formed at the tips of the lead parts (Sga) of the segment coil (SC) which protrude from the end face of the stator core (20) and are twisted together, at least one of the weld beads (Sgf) aligned in the radial direction of the stator (10) is an oblong body that is long in the radial direction of the stator core (20), and the angle formed by the longitudinal direction of the oblong body and the axial direction of the stator core (20) is less than 90 degrees in a core cross section that includes the central axis of the stator core (20).

摘要： A stator includes a stator core (12), a plurality of phase windings (20), a neutral line (50) and a fixing portion (70). The plurality of phase windings (20) is wounded a plurality of times by a predetermined winding method crossing between a plurality of slots (14). One lead end (42, 44, 46) of each phase winding (20) is a neutral point connecting portion, and the one lead end (42, 44, 46) is pulled out from an axially end portion of the stator core. The neutral line (50) connects the neutral point connecting portions (42, 44, 46) of the phase windings (20) of different phases together. The neutral line (50) is separate from the phase windings (20). The fixing portion (70) fixes a first phase winding that is connected to the neutral line (50). A second phase winding is adjacent to the first phase winding together.

摘要： A stator core capable of improving Stator core segments in assemblability, positioning accuracy and rigidity is provided. A stator core (141) includes a plurality of stator core segments (175), and a yoke part (176) of each stator core segment (175) has a first junction (178) and a Second junction (179) joined to other adjacent Stator core segments. A protrusion (193) is formed at the first junction (178), and a recess (196) capable of receiving the protrusion (193) is formed at the Second junction (179). The opening area of the recess (196) increases from a deepest section (196b) of the recess, (196) to an opening (196a) of the recess (196). In the yoke part (176), a first caulking site (187) where the stator core segment (175) is caulked in an axial direction (DR1) is formed on an arc passing through the central part of a radial length (r4) of the protrusion (193) and extending in a circumferential direction (DR2).
