Description

A kind of modified generator stator

Technical field

The utility model relates to stator structure design, specifically refers to a kind of modified generator stator.

Background technology

The generator unit stator disclosed in prior art, it can realize compact design, large power and low noise, its stator core equidistantly offers 96 rectangular channels, stator winding is made up of the conductor segment of multiple enamel-cover flat type copper wire, be connected with each other in the different layers inner wire section of different rectangular channel, to form the winding with high space factor and low resistance.But no matter existing stator winding adopts star connection or delta connection, still there will be the too low problem of generator power output, and insulate between each copper cash of stator winding and also there is the not good problem of reliability.In view of this, the stator of the present inventor to generator conducts in-depth research, and this case produces thus.

Utility model content

The purpose of this utility model is to provide a kind of modified generator stator, has the feature of the good and high-output power of compact conformation, flat type copper wire insulating properties.

In order to reach above-mentioned purpose, solution of the present utility model is:

A kind of modified generator stator, comprise iron core and the stator winding of winding on this iron core, this iron core is first-class is spacedly provided with 96 rectangular channels, and this each rectangular channel is divided into interior upper strata, interior lower floor, outer lower floor and outer upper strata from the inside to the outside successively by described iron core radial direction; Described stator winding is four layers of distribution, is equipped with a layer insulating paper between this adjacent two layers of four layers; Described stator winding is divided into symmetrical two groups, and often group is made up of 6 groups of stator flat coil groups, often organizes the magnetic pole logarithm P=8 of stator flat coil group; In the described 6 groups of stator flat coil groups often organized, wherein three groups of head and the tail triangles connect, and the tail end of other three groups connects described leg-of-mutton three head and the tail junctions respectively.

After adopting such scheme, this Novel photo is for the beneficial effect of prior art: this novel electricity generator lenticular wire stator is 96 grooves, stator winding is four layers of distribution, a layer insulating paper is equipped with between the adjacent two layers of four layers, namely every four layers of distribution are folded with three insulating papers layer by layer altogether, and each intercoil insulation is good, and winding adopts the cooperation of the star-like connection of trigonometric sum to realize orderly and compact distribution, whole stator coil copper factor is high, brings high-output power.

Embodiment

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

This case relates to a kind of modified generator 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 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, stator winding 2 is divided into symmetrical two groups, often group is made up of 6 groups of stator flat coil groups, wherein, magnetic pole logarithm P=8, often organizing stator flat coil group is unicoil group, and correspondence is distributed in 16 often corresponding rectangular channels, comprises 7 upper coils, 21,8 inner coils 22 and 2 winding leading-out wires 23.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, after phase coil is connected in series in turn according to above-mentioned rule, a winding leading-out wire 23 is also respectively drawn in its corresponding two ends, in the 6 groups of stator flat coil groups often organized, wherein three groups of head and the tail triangles connect, the tail end of other three groups connects described leg-of-mutton three head and the tail junction, i.e. C, D, E tri-connected nodes in pie graph 5 respectively, and the head end (A, B, F) of other three groups is drawn as winding leading-out wire.

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.
