摘要： A rotary electric machine includes: a floored cylindrical case in which an opening at a first end of a cylindrical portion is closed by a floor portion; a stator that includes: an annular stator core that is held inside the case by being fitted together with and fixed to the cylindrical portion; and coils that are mounted to the stator core; a frame that closes an opening at a second end of the cylindrical portion; and a rotor that is fixed to a rotating shaft, and that is disposed on an inner circumferential side of the stator, wherein: a first stress relieving indented portion is formed around an entire circumference at a first end of an inner circumferential surface of the cylindrical portion such that a gap is formed between a first end portion of an outer circumferential surface of the stator core and the cylindrical portion.

摘要： In an armature coil according to the present invention and, more particularly, in an armature coil including a plurality of coil conductors wound around a plurality of slots which are formed in a stator core and opened on the radially inner side, the circumferential width of the plurality of the coil conductors is formed in a substantially trapezoidal shape which gets narrower toward the radially inner side and the cross-sectional areas of the plurality of the coil conductors in the slot are each substantially the same and the circumferential width thereof is formed narrower as the coil conductor is arranged toward the radially inner side; and one coil conductor is formed in a convex shape and another coil conductor is formed in a concave shape along the convex shape.

摘要： A stator in which stator coils are formed by a plurality of unit coils arranged so as to be shifted from each other in the circumferential direction and each having: a first slot-accommodated portion; a second slot-accommodated portion; a first terminal wire extending from the first slot-accommodated portion; a second terminal wire extending from the second slot-accommodated portion and shifted from the first terminal wire by one line of a conductive wire; a terminal-side coil end portion; and first and second anti-terminal-side coil end portions, wherein the first terminal wire and the second terminal wire of the respective different unit coils are joined with each other.
