A winding assembly includes: slot-housed portions housed inside each of the slots of the stator core so as to form pairs that line up in an inner layer and an outer layer relative to a slot depth direction; first return portions at a first axial end of the stator core that link end portions of the slot-housed portions housed in the inner layer inside each of the slots and end portions of the slot-housed portions housed in the outer layer inside the slots that are (N−M) slots away; and second return portions at a second axial end of the stator core that link end portions of the slot-housed portions housed in the outer layer inside each of the slots and end portions of the slot-housed portions housed in the inner layer inside the slots that are (N+M) slots away.

The stator winding has winding assemblies that are disposed in a stator core so as to be stacked in three or more layers in a radial direction such that slot-housed portions line up in single columns in a clot depth direction inside slots, and radial widths of return portions of the winding assemblies that are mounted so as to be stacked in a radial direction are made sequentially narrower in order of return portions of a winding assembly that is positioned centrally, return portions of a winding assembly that is positioned on an inner circumferential side, and return portions of a winding assembly that is positioned on an outer circumferential side.

In a rotor of the present invention, an interference is set to have a relationship so that an inner diameter of a press-fit projecting portion before press-fitting is smaller than a diameter of a shaft, and in the inner wall surface, a non-projecting portion is formed without projecting portions on a portion in which a weld line is generated by the molding.

The stator winding includes: a first three-phase wye-delta hybrid winding that is configured by connecting phase windings of a first wye winding to respective output ends of a first delta winding; and a second three-phase wye-delta hybrid winding that is configured by connecting phase windings of a second wye winding to respective output ends of a second delta winding. The phase windings of the first and second wye windings are configured by connecting two winding portions in parallel, and those two winding portions are configured such that distributions of radial positions inside slots of conductor wires that constitute the winding portions are equal.

A lead wire connection structure includes a rectifier that is arranged at the outside or the inside in an axis direction of the brackets so as to rectify AC voltage, which is generated on the stator, to DC voltage; in which, when a number of conductors of a connecting portion, at which lead conductors of the stator winding and the rectifier are connected, is “N” (N is integer and greater than or equal to 2) per one position, conductors, of which number is less than or equal to “N−1” per one position, are connected at the connecting portion, and conductors excepted from the conductors, of which number is less than or equal to “N−1”, are welded onto the remaining conductors at a position being nearer the stator winding side than the connecting portion.

A dynamoelectric machine that can suppress increases in rotor inertia to extend belt service life and increase field magnetomotive force to increase output. In the dynamoelectric machine, first and second magnetic guidance members are fitted into first and second holding grooves that are disposed so as to extend axially on facing portions of first and second trough portions radially outside inner wall surfaces, and are disposed so as to span over first and second trough portions. First and second permanent magnets that are magnetically oriented in a reverse direction to a magnetic field that originates from a field coil are fitted into and held by interfitting grooves of the first and second magnetic guidance members so as to face inner circumferential surfaces near tip ends of second and first claw-shaped magnetic pole portions so as to have a predetermined clearance.
