In same phase, an optional stator slot 110 is as the winding end of the first connecting line group 240, and this illustrates as a example by sentencing this phase shown in Fig. 1, i.e. using the 13rd groove as the stator slot 110 at the place, winding end of the first connecting line group 240.nullThe stator slot 110 at the place, winding end of the first connecting line group 240 is adjacent with the stator slot 110 at the place, winding end of the second connecting line group 250，It is separated with five grooves between the stator slot 110 at the stator slot 110 at the place, winding end of the first connecting line group 240 and the place, winding end of the 3rd connecting line group 260，It is separated with six grooves between the stator slot 110 at the stator slot 110 at the place, winding end of the first connecting line group 240 and the place, winding end of the 4th connecting line group 270，Simultaneously，Second connecting line group 250、The winding end of the 3rd connecting line group 260 and the 4th connecting line group 270 lays respectively at the side that the winding end of the first connecting line group 240 is in opposite direction with winding，The winding end of the i.e. second connecting line group 240 is positioned at the 14th groove，The winding end of the 3rd connecting line group 250 is positioned at the 19th groove，The winding end of the 4th connecting line group 260 is positioned at the 20th groove.
It should be noted that in FIG, dotted line represents the corresponding connecting line group part stopped by the iron core 100 described in Fig. 1.
Winding end self-assembling formation the first lead-out wire group 280 of the first connecting line group 240, tail end self-assembling formation the second lead-out wire group 290 of the 4th connecting line group 270, first cross-line 210 is connected between the tail end of the first connecting line group 240 and the winding end of described second connecting line group 2505, second cross-line 220 is connected between tail end and the winding end of the 3rd connecting line group 260 of the second connecting line group 250,3rd cross-line 230 is connected between tail end and the winding end of the 4th connecting line group 270 of the 3rd connecting line group 260, that is to say that each connecting line group is cascaded by each cross-line.
Stator winding 200 is respectively stated the second lead-out wire 290 groups mutually and is connected with each other, and in stator winding 200 between adjacent the first biphase lead-out wire 280 between be separated with a groove, so can ensure that the stator slot 110 shared by each phase does not repeats mutually.
Embodiment two:
As it is shown on figure 3, being distinguished as of the present embodiment and embodiment one, in the present embodiment, stator winding 200 often the most also includes the first lead-out wire 281 and the second lead-out wire 291, and the first lead-out wire 281 and the second lead-out wire 291 are all the flat type copper wire in flat.The winding end of the first connecting line group 240 is connected with one end of the first lead-out wire 281, the tail end of the 4th connecting line group 270 and one end of the second lead-out wire 291 are connected, certainly, the winding end of the first connecting line group 240 in the present embodiment and the tail end of the 4th connecting line group 270 are not forming lead-out wire group.
Additionally, in the present embodiment, in stator winding 200 between adjacent the first biphase extraction 281 between be separated with three grooves.
Above in conjunction with accompanying drawing, this utility model is described in detail; but embodiment of the present utility model is not limited in above-mentioned embodiment; this utility model can be made various deformation according to prior art by those skilled in the art; as changed the quantity etc. of flat type copper wire in each line group, these broadly fall into protection domain of the present utility model.
