Embodiment

Below in conjunction with the drawings and specific embodiments, this case is described in further detail.

This case relates to a kind of generator lenticular wire stator, as Figure 1-5, mainly comprises iron core 1 and the stator winding 2 of winding on this iron core 1.

As shown in Figure 1, iron core 1 is first-class is spacedly provided with 96 rectangular channels 10, is equipped with a slot insulating paper (in figure do not indicate) suitable with this rectangular channel 10 in this each rectangular channel 10 along its rectangular groove wall.As shown in Figure 2, if each rectangular channel 10 divides by the arrangement of the stator coil 2 in it four layers, it is followed successively by interior upper strata 101, interior lower floor 102, outer lower floor 103 and outer upper strata 104 from the inside to the outside by iron core 1 radial direction.Corresponding described four layers of design, stator winding 2 is the three-phase windings of employing four layers distribution, as shown in Figure 3, layer insulating paper 3 is equipped with between this adjacent two layers of four layers, namely three insulating papers 3 are layer by layer folded with between four layer line circles altogether, namely carry out the two-layer enamel wire coil of space between adjacent with layer insulating paper 3, thus interturn in stator windings or alternate breakdown problem may be caused to coil varnish covering burn when avoiding welding, guarantee the excellent service behaviour of stator coil with this.

Be the Winding Design of stator winding 2 as illustrated in figures 4-5, wherein, magnetic pole logarithm P=8, MgO-ZrO_2 brick q=2, then the stator flat coil of every phase can be divided into two coil groups, and the stator flat coil of this every phase correspondence is distributed in 32 often corresponding rectangular channels, comprise 30 upper coils, 21,30 inner coils 22,2 serial connection coil 23,1 cross-over connection coil 24 and 2 winding leading-out wires 25.In this Three phase winding, the schematic diagram of each corresponding iron core rectangular channel number is as follows:

As shown in Figure 2, Figure 4 shows, the pitch of inner coil 21 is 6, for being crossed on the progressive coil in two rectangular channels between lower floor 102 and outer lower floor 103; The pitch of upper coil 22 is 6, for being crossed on ripple in two rectangular channels between upper strata 101 and outer upper strata 104 around formula coil.As shown in Figure 5,2 serial connection coil 23 respectively the connection of corresponding described two coil groups separately between levels coil get lines crossed, it is crossed between the interior upper strata 101 of two rectangular channels and outer lower floor 103; Connection cross-line between corresponding described two coil groups of described 1 cross-over connection coil, it is crossed between the outer upper strata 104 of correspondence of two rectangular channels.After this phase coil is connected in series in turn according to above-mentioned rule, a winding leading-out wire 25 is also respectively drawn in its corresponding two ends.Every phase winding realizes the orderly and compact distribution of 64 coils by 2 serial connection coils 23 and 1 jumper turn coil 24, and coil copper factor is high, can bring high-output power.

The foregoing is only the preferred embodiment that this is novel, all equalizations done with this novel right change and modify, and all should belong to the scope of this novel claim.
