Abstract: A stator includes an annular stator core and a stator coil. The stator core has a plurality of slots formed therein. The stator coil includes first to third phase windings mounted on the stator core and a connection portion located outside the slots of the stator core. The connection portion is formed of a first connection wire connecting the first and second phase windings and a second connection wire connecting the third phase winding to the first connection wire. The first connection wire is arranged so as to extend in the circumferential direction of the stator core. The second connection wire is bent to include a bend and an intersecting part that extends from the bend to the first connection wire so as to intersect the first connection wire. The intersecting part of the second connection wire is joined to the first connection wire with a joint formed therebetween.

Abstract: Each of claw-shaped magnetic poles is formed with an air gap expanding portion formed on at least a portion of both side portions in a circumferential direction, and an air gap is formed between the air gap expanding portion and tip portions of teeth that is larger than another air gap formed between radial end portions and the tip portions of the teeth. When a circumferential distance between the radial end portion and the tip portion is indicated by τ, and when the air gap is indicated by δ, 3δ≦τ≦15δ is satisfied. When a claw-tip end face width is indicated by L1, and when a claw-root end face width is indicated by L2, the claw-shaped magnetic pole is formed in a range of 0.20≦L1/L2≦0.71.
