摘要： The stator of a dynamoelectric machine, and it manufacturing method, in which the slot containing part has a race track-like cross-section and an insulation property can be enhanced by protecting the insulation coating against damage at the time of fixing the stator winding to the stator core. The slot containing part of the stator winding has a race track-like cross-section and the slot containing parts are contained in the slots while being arranged in a row in the radial direction with the longitudinal direction of the cross-section being directed toward the circumferential direction. Since the short side of the slot containing part facing the inner circumferential side face of the slot becomes a convex surface, the insulation coating is protected against damage due to rubbing of the short side of the slot containing part against the inner circumferential side face of the slot at the time of inserting the slot containing part into the slot to thereby enhance an insulation property.

摘要： A rotor for a dynamo-electric machine in which an odd stage is arranged such that coil wires are turned in a plurality of rows in the axial direction to touch each other after turning substantially once around the winding body section while touching the inner circumferential wall face at the first flange section (18) of a bobbin and a coil wire in the last row has a gap S with respect to the inner circumferential wall face at the second flange section (19) of the bobbin, whereas an even stage is arranged such that the first row touches the inner circumferential wall face at the second flange section and the last row has a gap S with respect to the inner circumferential wall face at the first flange section when a coil wire having a circular cross-section is wound in multistage around the outer circumference of the winding body section of the bobbin while equalizing the number of rows of respective stages in the axial direction. The gap S and the diameter D of the coil wire satisfy a relation D/4

摘要： An AC generator for a vehicle, in which high output is realized by overlapping a laminated iron core of a stator with a yoke part of a field rotor in the axial direction, and an electromagnetic sound at high and low speed can be reduced by defining the dimensional relation between the stator and the field rotor. The ratio (R2/R1) of the outside diameter (R2) of a cylinder of a Lundell iron core to the outside diameter (R1) of the Lundell iron core is in the range of 0.50-0.54, and the ratio (Lc/Lp) of the length (Lc) of the laminated iron core in the axial direction to the length (Lp) of the Lundell iron core in the axial direction is in the range of 0.55-0.70.

The brush holder assembly has a base and a plate. The base is prepared by molding a brush holder portion, a regulator circuit housing portion, and a connector portion integrally, and the plate is mounted to the brush holder portion, and has a cover portion that closes the resin injection aperture of the regulator circuit housing portion. The brush holder portion, the regulator circuit housing portion, and the connector portion are formed so as to be positioned such that respective center lines thereof are in a common plane that includes a central axis of the rotating shaft. A lead-through opening that is formed on the rear bracket so as to allow the connector portion to be led through is generally closed by the connector portion and the cover portion.

摘要： The present invention provides an AC generator for a vehicle, in which a resin case (26) includes convex portions (33) formed on an outer circumferential surface of the resin case (26) so as to extend in an axial direction of the resin case (26) to be brought into pressure-contact with an inner circumferential wall surface of a counter drive-side bearing housing portion (24), and convex portions (34) formed on an inner circumferential surface of the resin case (26) so as to be opposed to the convex portions (33). The concave portions (34) allow displacement of the convex portions (33) in a radially inward direction of the resin case (26). By an elastic force generated by the displacement of the convex portions (33), the resin case (26) is integrated with the counter drive-side bearing housing portion (24).

摘要： An automotive alternator is provided that reduces exclusive circumferential space for a regulator assembly inside a rear bracket, and that also increases performance in cooling the regulator assembly and a rectifier by ensuring that flows of air that cool the regulator assembly and the rectifier do not interfere with each other. An approximately C-shaped rectifier is disposed in a vicinity of a rotating shaft, and a regulator assembly is disposed between two end portions of the approximate C shape of the rectifier. A brush holder portion, a regulator circuit housing portion, and a connector portion that constitute a regulator assembly are positioned such that respective center lines thereof are in a common plane that includes a central axis of the rotating shaft. A partitioning wall is disposed so as to project from an inner wall surface of the rear bracket so as to separate a rectifier cooling airflow passage for cooling the rectifier and a regulator circuit cooling airflow passage for cooling the regulator circuit by stopping circumferential flow of air that is sucked in through the suction aperture to cool the rectifier and the regulator circuit respectively.
