    摘要： A stator includes a stator core (13) having a substantially cylindrical back yoke (11) and a plurality of teeth (12) extending radially inward from the back yoke (11). The stator core (13) includes a plurality of stator core pieces (13a) each having one tooth (12) and a yoke piece (11a) forming part of the back yoke (11). On the inside of the back yoke (11) in the radial direction, adjacent ones of the stator core pieces (13a) directly contact each other, or contact each other with a member, as an intervening thing, interposed between the adjacent ones of the stator core pieces (13a).

    摘要： Die Erfindung betrifft ein Statorsegment (3) eines Stators (2) einer dynamoelektrischen Maschine (1) mit
    - axial hintereinander angeordneten genuteten Blechen, so dass im Wesentlichen axial verlaufende Nuten (7) gebildet sind,
    - Abstandshaltern (6), die nach einer vorgebbaren Anzahl von Blechen in axialer Richtung vorgesehen sind, so dass in axialer Richtung betrachtet zwei oder mehrere Teilblechpakete (4) des Statorsegments (3) vorhanden sind, die durch Spalte (5) getrennt sind,
    - in den Nuten (7) angeordneten Spulen (12), wobei in einer Nut (7) eine Spulenseite (24) oder zwei Spulenseiten (24) unterschiedlicher Spulen (12) angeordnet sind,
    - zumindest einer offenen Nut (8) an den nutparallelen äußeren Begrenzungsseiten der Bleche,
    - Befestigungsmitteln, die die Spulenseiten (24) in den offenen Nuten (13) an dem Statorsegment (3) fixieren, wobei Fixierhilfselemente (14) im Bereich der Spalte (5) zwischen den Teilblechpaketen (4) angeordnet sind und über die eine Fixierung der Spulenseiten (24) in den offenen Nuten (8) am Blechpaket mittels Bandagen (19) erfolgt.

    摘要： A stator used for a motor and having excellent vibration resistance, waterproofness, and an insulating property. The stator used for a motor includes a stator core having a plurality of teeth arranged at substantially equal intervals on a same circumference, and an insulator covering the teeth, and coil portions are formed by wires being winded around portions of the insulator that covers the plurality of teeth. The insulator includes first wall portions provided on the center axis side with respect to the coil portion, and molded portions formed, by resin, on the center axis side with respect to the first wall portions. Wire extended portions of the wire pulled out from the coil portion straddle the first wall portions. Wire terminal end portions are connected to bus rings. The bus rings are embedded in the molded portions.

    摘要： A first portion (61) of an insulator (60) is provided on a first region (R1) of an end surface (S3) of a tooth (35). A second portion (63) of the insulator (60) is provided on a second region (R2) of the end surface (S3) of the tooth (35) so as to be separated from the first portion (61) in a circumferential direction. A third portion (65) of the insulator (60) is connected to fourth side ends of the first portion (61) and the second portion (63) in a radial direction. A coil (50) includes a crossing portion (52) in a coil end (51). A stator (30) includes an insert body (82) in a housing space (SP). The insert (82) is made of a material having a higher thermal conductivity than a material forming the insulator (60).

    摘要： An insulator 5 includes a part 50 to be wound with a coil 7; a first flange 51; and a second flange 52. The first flange 51 is formed at the side of the part 50 closer to a core segment 41, and includes a coil guide groove 53 that guides the coil 7 to the part 50. The second flange 52 is formed at the side of the part 50 closer to a distal end of a teeth 42. The coil guide groove 53 includes a first guide groove 53a and a second guide groove 53b symmetrical with respect to a radial plane. Each of the first and second guide grooves 53a and 53b extends at an acute angle θ from an inner surface 51a of the first flange 51.
