Embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details:
Shown in Fig. 1-4,
(1) a kind of situation: 2 composite type windings that II type coil winding is nested to form
(2) another kind of situation: 1 I type coil winding and 1 composite type winding that II type coil winding is nested to form
I type coil winding and coil II type coil winding are comprised of coils same number, a plurality of, and the wire diameter of each coil is consistent with the number of turn.
Two kinds of winding coils are with identical bobbin and respectively once property coiling on high-speed winding machine of self-adhesive enameled wire.(skeleton is not stayed in the winding, and is reusable)
Bobbin adopts dismountable structure in the winding forming process, be used in conjunction with forming frock, and utilize enamelled wire self-adhesion characteristic, can be easily simply respectively coil processing that coiling is good be shaped into II type coil winding shown in Figure 1 and I type coil winding shown in Figure 3.
I type coil winding and II type coil winding adopt the triangular form connection that A, B, three exits of C are arranged respectively, and [3 coils are totally 6 lines, then short circuit in twos, form 3 exits], when embedding combination, with two A that winding is corresponding, B, the C lead-out wire is in parallel, consists of the equally distributed whole winding of a symmetry.The whole winding A that is produced by parallel connection, B, the C lead-out wire is connected with the driving connector of motor.Two A that winding is corresponding, B, the C lead-out wire is in parallel, has reduced the internal resistance of coil.
Coil I type coil winding and coil II type coil winding adopt two kinds to embed compound mode:
Combination one: embed another II type coil winding (seeing Fig. 2) in the II type coil winding.This combination is by embedding combination after the independent moulding of two II type coil windings.
Combination two: embed coil II type coil winding (seeing Fig. 4) in the I type coil winding.This combination I type coil winding embeds II type coil winding after the moulding in stator.--this combination can accomplish that axial dimension is shorter.This combination requires I type coil winding and stator one-body molded;
Therefore, combination two motor axial dimension makes up one little (because the lower edge of I type coil winding can take full advantage of the axial length of stator in the combination one outside stator), and it is one easy that the embedding combination operation of combination one is made up.
Winding situation when above embodiment has provided N=1, need to prove, situation for N=2 even N＞2 o'clock, those of ordinary skill in the art can adopt the coiling that uses the same method fully, for example during N=2, I type coil winding or II type coil winding are comprised of equally distributed 6 groups of coils, and namely A phase coil, B phase coil and C phase coil are each 2 groups, the coils from parallel connection of coils of homophase; The nested mode of composite type winding coil is identical.Thereby, needn't be described in detail, those skilled in the art will appreciate that embodiment of the present utility model is not limited to the example of aforementioned support, protection range of the present utility model is as the criterion with claims.
