  • Patent number: 11038395
    Abstract: A winding-start receiving groove in which a winding-start lead wire of a field coil is received is formed in an inner surface of a flange of an insulation bobbin. A holder is disposed on the flange and located on a radially outer side of the winding-start receiving groove. The holder is formed with a holder groove located on an extension line of the winding-start receiving groove and extending at an angle relative to a radial direction of the insulation bobbin. The winding-start lead wire of the field coil is received in the winding-start receiving groove and the holder groove and held by the holder. This makes it possible to obtain a rotor of a rotary electrical machine with a simplified configuration at low cost not only to improve winding workability but also to enhance electrical reliability and durability.

  • Patent number: 10848028
    Abstract: A detachment prevention portion extending in a circumferential direction of a flange portion of a bobbin from a neck portion of a locking portion provided so as to extend radially outward from the flange portion is formed such that a length by which the detachment prevention portion extends to one side in the circumferential direction is longer than a length by which the detachment prevention portion extends to another side in the circumferential direction. Accordingly, interference between cover portions and a field coil winding or between the cover portions and a winding jig for the winding during operation of winding a lead wire of the winding can be inhibited while electric insulation between a field coil and claw-shaped magnetic poles is ensured.

  • Patent number: 9705272
    Abstract: A restricting member is provided that is in contact with respective bent lead portions of a long-sized lead and a short-sized lead and imparts a tension to linear lead portions thereof in a mold for insert molding. The restricting member reliably prevents the leads from displacement and deformation resulting from the pressure of the resin at the time of insert molding, and allows the long-sized lead and the short-sized lead to be disposed at proper positions in a molded body.

  • Patent number: 9472994
    Abstract: 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).
