Abstract
The generator winding internal stator iron core that the utility model has waveform yoke portion is related to generator winding internal stator iron core, it is by silicon steel sheet section bar is wound, being layering forms, it is yoke portion on the inside of silicon steel sheet section bar, outside is teeth portion, the yoke portion of silicon steel sheet section bar is convex with respect to teeth portion, yoke portion deformation part is in semiellipse, and semiellipse end is pointed among coiling clip foot bottom.The rear of core that the utility model is wound is wider, improves the performance of generator, and yoke portion is more easily manufactured without departing from material deformation scope.
Description
Technical field
It the utility model is related to gen-set technical field, and in particular to have in the generator winding in waveform yoke portion
Stator core.
Background technology
Conventional electric generators are unshakable in one's determination to be wound making moulding process for most of control cost using band, uses the manufacture
There are the following problems for the stator core of technique manufacture and stator：
As shown in Figure of description 1, rear of core deforms upon larger in winding process, band yoke in winding process
Portion's outer rim is stretched, and Inner edge are compressed.Because material deformation is limited in scope, winding process is not suitable for the larger generator of yoke portion width
It is unshakable in one's determination.This kind of winding process use range is narrow.The finished product yoke portion narrow width of internal stator iron core is wound, limits the property of generator
Energy.
Utility model content
The purpose of this utility model is to solve the above problems, there is provided in a kind of generator winding with waveform yoke portion
Stator core.
In order to solve the above problems, the technical solution adopted in the utility model is as follows：
Generator winding internal stator iron core with waveform yoke portion, it is by silicon steel sheet section bar winding, being layering forms,
It is yoke portion on the inside of the silicon steel sheet section bar, is teeth portion on the outside of the silicon steel sheet section bar, teeth portion outward flange has dentation coiling card base
With " u "-shaped winding slot, the coiling card base and winding slot are uniformly interspersed, it is characterised in that the teeth portion phase of silicon steel sheet section bar
Convex to yoke portion, yoke portion deformation part is in semiellipse, and semiellipse end is pointed among coiling clip foot bottom.
Compared with prior art, it is the advantages of the utility model：Due to the waveform deformation using teeth portion and yoke portion, offset
In silicon steel sheet section bar winding process, the compressive deformation of inward flange, outer peripheral tensile deformation can be certain in material deformation rate
Under conditions of can use the broader silicon steel sheet section bar in yoke portion, the rear of core wound is wider.And the utility model is rolled up
The generator core laid out is more easily manufactured without departing from material deformation scope due to yoke portion.The utility model is reduced in winding
The manufacture difficulty of stator core, is advantageously implemented automated production, because there is the iron core wound broader yoke portion to improve
The performance of generator.
Brief description of the drawings
, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art
Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only

Description of reference numerals：Yoke portion -1, yoke portion deformation part -11, teeth portion -2, coiling card base -21, winding slot -22.
Embodiment
Preferred embodiment of the present utility model is described in detail below in conjunction with the accompanying drawings, so that the advantages of the utility model
It can be easier to be readily appreciated by one skilled in the art with feature, it is apparent clear and definite so as to be made to the scope of protection of the utility model
Define.
Refering to shown in Figure of description 3, the utility model provides the generator winding inner stator iron with waveform yoke portion
The heart, it is yoke portion 1 by silicon steel sheet section bar is wound, being layering forms, on the inside of the silicon steel sheet section bar, outside the silicon steel sheet section bar
Side is teeth portion 2, and the outward flange of teeth portion 2 has dentation coiling card base 21 and " u "-shaped winding slot 22, the coiling card base 21 and winding slot
22 are uniformly interspersed, it is characterised in that and it is convex with respect to teeth portion 2 refering to the yoke portion 1 of silicon steel sheet section bar shown in Figure of description 2,
Yoke portion deformation part 11 is in semiellipse, and semiellipse end is pointed among the bottom of coiling card base 21.
The advantages of general principle of the present utility model, principal character and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, retouching in above-described embodiment and specification
Preference only of the present utility model is stated, the utility model is not limited by above-mentioned preference, is not departing from the utility model
On the premise of spirit and scope, the utility model can also have various changes and modifications, and these changes and improvements both fall within this practicality
In new claimed scope.
While there has been shown and described that embodiment of the present utility model, for the ordinary skill in the art,
It is appreciated that these embodiments can be carried out with a variety of changes in the case where not departing from principle of the present utility model and spirit, repaiied
Change, replace and modification, the scope of the utility model are defined by the appended claims and the equivalents thereof.
