Abstract
The utility model relates to the motor field, especially relates to a stator punching sheet. The stator punching sheet is characterized in that a square stator punching sheet body is provided, and a center of the stator punching sheet body is provided with a stator inner hole; a peripheral surface of the stator punching sheet body facing the stator inner hole is provided with a plurality of stator magnetic poles, and one side of each of the magnetic poles facing the stator inner hole is provided with a stator pole shoe, in addition, a surface of each of the stator pole shoes facing the stator inner hole is an arc surface. The stator punching sheet is also characterized in that the distance between each of the pole shoe surfaces and the center of the stator inner hole can be gradually reduced from a middle part of each of the pole surfaces to two ends. The stator punching sheet is advantageous in that the pole shoe surfaces are in a non-concentric arc arrangement, and therefore the air gap is variable, the intensity of the air gap magnetic field can be changed, the air gap structure can be more reasonable, and the performance of the stator punching sheet can be improved.
Description
Technical field
The utility model relates to machine field, refers to especially a kind of stator punching.
Background technology
Stator is the actionless part of motor, and stator is comprised of stator core, stator winding and support three parts, and the Main Function of stator is to produce rotating magnetic field.Wherein stator core is interfixed vertically and formed by the punching of multi-disc electronics.
The stator punching of prior art; Comprise the stator punching body and be located at the stator inner hole at stator punching body center; The stator punching body is provided with a plurality of magnetic pole of the stator on the side face of stator inner hole; Each magnetic pole of the stator is respectively equipped with stator pole shoes towards a side of stator inner hole; The pole-shoe face towards stator inner hole of each stator pole shoes is arc surface; The arc surface of each stator pole shoes is isocentric circular arc; During the motor stator assembling motor that laminates with this stator punching; Space between rotor and pole-shoe face is air gap; Air gap between whole pole-shoe face and rotor is changeless; The density of air-gap field immobilizes; Cause gap structure unreasonable; Affect the performance of stator punching.And when stator core is loaded in support, for positioning element is set, cause stator core to be difficult to be fixed in support due to the side face of stator punching, cause the stator laminating structure layout unreasonable.
The utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of stator punching performance the higher and rational stator punching of topology layout.
The technical solution of the utility model is achieved in that a kind of stator punching, comprise the stator punching body that is square, the center of this stator punching body is provided with stator inner hole, this stator punching body is provided with a plurality of magnetic pole of the stator on the side face of stator inner hole, and each magnetic pole of the stator is respectively equipped with stator pole shoes towards a side of stator inner hole, each stator pole shoes is arc surface towards the pole-shoe face of stator inner hole, and the middle part of described each pole-shoe face to the distance at the center of stator inner hole from pole-shoe face reduces gradually to two ends.
By adopting technique scheme, pole-shoe face is non-isocentric circular arc setting, and then air gap is variable, thereby has changed the density of air-gap field, makes gap structure more reasonable, has improved the performance of stator punching.
The utility model further is set to: be symmetrically arranged with two detents on the periphery up and down of described stator punching body.
Wherein, the width in the middle part of described detent reduces gradually to two ends.
By adopting technique scheme, be conducive to stator core and be installed in support, and the stator laminating structure layout is more reasonable, and simple in structure, be easy to realize.
The utility model also further is set to: be symmetrically arranged with two location holes on the left and right periphery of described stator punching body.
By adopting technique scheme, can further be fixed the stator punching body, the accuracy of location is more accurate, and topology layout is more reasonable.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or description of the Prior Art, apparently, accompanying drawing in the following describes is only embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model embodiment structure vertical view;
Fig. 2 is the A section enlarged drawing of Fig. 1.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, the technical scheme in the utility model embodiment is clearly and completely described, obviously, described embodiment is only the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As Fig. 1-shown in Figure 2; The utility model discloses a kind of stator punching; Comprise the stator punching body 1 that is square; The center of this stator punching body 1 is provided with stator inner hole 14; This stator punching body 1 is provided with a plurality of magnetic pole of the stator 11 on the side face of stator inner hole 14; And each magnetic pole of the stator 11 is respectively equipped with stator pole shoes 12 towards a side of stator inner hole 14; Each stator pole shoes 12 is arc surface towards the pole-shoe face 121 of stator inner hole 14; In the utility model specific embodiment; The middle part of described each pole-shoe face 121 to the distance at the center of stator inner hole 14 from pole-shoe face 121 reduces gradually to two ends; Be a〉b; A〉c; This pole-shoe face 121 is non-isocentric circular arc setting; And then air gap is variable; Thereby changed the density of air-gap field; Make gap structure more reasonable; Improved the performance of stator punching.
Wherein, two ends, pole-shoe face middle part are symmetrical arranged in the middle part of pole-shoe face to the distance at the center of stator inner hole, i.e. a〉b, a〉c, and a=c.Certainly, two ends, pole-shoe face middle part can unequally arrange to the distance at the center of stator inner hole, i.e. a〉b, a〉c, a is not equal to c.
In the utility model specific embodiment, be symmetrically arranged with two detents 13 on the periphery up and down of described stator punching body 1, wherein, the width L at described detent 13 middle parts reduces gradually to two ends, being conducive to stator core is installed in support, and the stator laminating structure layout is more reasonable, and simple in structure, is easy to realize.
In the utility model specific embodiment, be symmetrically arranged with two location holes 15 on the left and right periphery of described stator punching body 1, can further be fixed the stator punching body, the accuracy of location is more accurate, and topology layout is more reasonable.
The above is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any modification of doing, be equal to replacement, improvement etc., within all should being included in protection range of the present utility model.
