Abstract
The present invention relates to a monomer of stator and its making method. Said monomer of stator is made into columnal body, and has three parts of first end zone,second end zone and middle zone. Said first end zone and second end zone are connected to both sides of middle zone toward one side of monomer and close to one. Said columnal body is formed by several overlapped magnetic conductive plates.
Description
The present invention relates to be applied to the monomer and the manufacture method thereof of motor or generator unit stator.
See also Figure 15, the iron core 80 of known motor stator is to pile up riveted mutually by the about 0.5mm-0.35mm lamination 81 of a slice a slice thickness to form, lamination 81 is for having several tooth portions 82, several slotted eyes 83 and a hollow grooved ring, when this iron core 80 is processed into motor stator, following engineering and shortcoming are arranged: (1) needs punch press and die stamping to form a complete lamination 81, at the silicon steel sheet material bar in punching course, maimed person's material of its slotted eye 83 and periphery is a lot, and general defective material ratio is all more than 40%, and waste material is very huge, see also Figure 16, oblique line partly is maimed material, thus increase huge cost, and punch press, the cost of mould is also expensive.(2) and because coiling is complicated, so needs are expensive and the coil winder of complicated formality, reshaper, wiring machinery etc., its investment goods complex and expensive.(3) for as thin as a wafer magnetic electromagnetism steel, as thickness only is 0.2mm, 0.1mm, noncrystalline such as 0.025mm, 0.018mm even, high permeability, low iron loss, hardness height, the crisp and high efficiency magnetic electromagnetic steel sheet material of easy fracture, punching machine mold is difficult for processing, and this type of efficient material still can't use on rotary electric machine at present.
The objective of the invention is to propose that a kind of not only manufacture craft is simple for it by causing plate, line to close the monomer and the manufacture method thereof of the stator of being formed after seat and the light procedure of processing of coil, and can economical with materials, thereby the existing in prior technology problem solved.
The technical solution adopted in the present invention is that it comprises a column, this column is prolonged by its top side and extends longitudinally to its bottom side, and slightly be divided into first petiolarea, second petiolarea and stage casing district, wherein first petiolarea and second petiolarea are linked to the both sides in stage casing district respectively, and the inboard towards monomer is close, and inboard opposite side forms the outside, and this column is to be formed to lateral direction is folded mutually by the inboard by the number magnetic conductive board.
The present invention makes the step that monomer methods comprises to be had:
(a) with a roll bar one magnetic conductive board coiling is repeatedly formed an annular solid;
(b) the annular solid gummed is fixing; And
(c) annular solid is cut into several columns.
The invention has the advantages that: it can save raw material, can make the ratio of maimed material can approach zero; Next is to have simplified the method for making motor or generator unit stator; The 3rd is that the present invention can use magnetic conductive board as thin as a wafer, makes that the stator eddy current loss is few, and flux density is concentrated, and the reduction of motor or generator-temperature detection is reached raise the efficiency greatly.

Figure 16 makes the maimed person that iron core the produced material of known motor stator for demonstration.
Further specify preferred embodiment of the present utility model in conjunction with above-mentioned each accompanying drawing now, please refer to Fig. 1-Fig. 5 makes the monomer 10 of stator for the present invention method.Need cut 20 one-tenth needed material width of a magnetic conductive board according to the power of making the design of motor or generator unit stator, this magnetic conductive board 20 can adopt as magnetic electromagnetic steel sheet or other has the material of magnetic conduction.Generally speaking for to make end product (being the monomer 10 of stator) magnetic conductivity good, preferably earlier insulating barrier 201 is coated on magnetic conductive board 20 surfaces earlier.And then with roll bar 60 magnetic conductive board 20 is reeled and repeatedly to form an annular solid 23, after being wound to needed thickness, still unwound magnetic conductive board 20 is excised, and with last tail end welding (seeing the pad 29 of Fig. 3), can give heat treatment to eliminate stress this moment with annular solid 23, more fixing (such as gummeds such as impregnation all power water insulating varnish or the resin) mode of annular solid 23 gummeds handled.
Be two to obtain the monomer 10 of two stators at last with annular solid 23 cuttings, be shaped as slightly the cylindrical slot 19 of " " type and since annular solid 23 in advance gummed fix it, so several magnetic conductive boards 20 that the monomer 10 of stator piles up can not scatter.In addition since annular solid 23 make with winding method, so magnetic conductive board of the present invention 20 can be extremely thin.
The most generally be to be processed into " shape of a hoof " shape optionally with column 19 bending processes this moment, as shown in Figure 6, and to obtain preferable magnetic conduction effect.For convenient explanation thereafter, these column 19 thinner portions are defined as follows in addition.This column 19 is to be prolonged by its top side 16 to extend longitudinally to its bottom side 17, and slightly be divided into first petiolarea 11, second petiolarea 12 and stage casing district 13, wherein first petiolarea 11 and second petiolarea 12 are linked to the both sides (winding around and energising back form the N utmost point and the S utmost point) in stage casing district 13 respectively, and the inboard 14 towards monomer 10 is close, and inboard 14 opposite side forms the outside 15.Because through the process of above-mentioned manufacturing, this column 19 is that 15 directions are folded mutually forms to the outside by inboard 14 by several magnetic conductive boards 20.
See also Fig. 7, can conduct electricity and outer coil 30 (as enamel covered wire) with insulating barrier, be to be wound in column 19, wherein coil 30 is the top sides 16 of repeatedly twining by column 19, inboard 14, the bottom side 17 and the outside 15, the position that coil 30 twines is the stage casing district 13 that is positioned at column 19, but also can be as shown in Figure 8, the position that coil 30 twines is to be positioned at first petiolarea 11 and second petiolarea 12.When winding around 30,, preferably earlier coil holder 31 is fixed in the position that will twine in addition for conveniently twining and avoiding coil 30 insulating barriers to be cut by magnetic conductive board 20 edges.
Fig. 9-Figure 11 is for being applied to the monomer 10 of stator of the present invention the embodiment of motor stator, and wherein motor mover 91 is positioned at the central authorities of motor stator.Fig. 9 demonstration is formed a motor stator by the monomer 10 of three stators, and coil 30 is wound in first and second petiolarea 11,12.Figure 10 and Fig. 9 difference are that coil 30 is wound in stage casing district 13, and first and second petiolarea 11,12nd, through being processed into concave arc 18 so that with motor mover 91 fluid-tight engagement.Figure 11 shows and to form a motor stator by the monomer 10 of six stators, and wherein the position of coil 30 windings is positioned at first petiolarea 11 and second petiolarea 12, but monomer 10 petiolareas of coil 30 stator that each is adjacent twine together.
More than make annular solid 23 and be noted that roll bar 60 can have other variations, such as Figure 12 shows that the cross section is leg-of-mutton roll bar 60, thus 23 one-tenth triangular shapes of annular solid, so can cut into three columns 19; Or, therefore can cut into four columns 19 as the octagonal annular solid 23 of Figure 13; Or even as the annular solid 23 of the 14th figure, and can cut into the column 19 of any several piece.
Be noted that above-mentioned only is embodiment, the interest field that this patent is advocated should be as the criterion with claim, but not is limited to embodiment.
