Description
Technical field
The utility model belongs to novel stator punching technical field, refers in particular to a kind of novel stator punching.
Background technology
The stator punching of motor be for conducting electromagnetic field, it is but often unavoidable in the course of work of electromagnetic field
Appearance eddy-current heating effect, and the method for tackling such case at this stage, are to combine stator punching burst, and between every layer
Need to coat the high insulating cement of insulating properties, eddy current effect is reduced using laminated insulation, so that fever is reduced, but what is be layered determines
Although can be obstructed between sub- punching using insulating cement, difficulty is brought to the fixation between stator punching, simple
Using insulating cement progress glue and it is completely inadequate, is so not sufficiently stable, easily the offset of generation stator punching, and motor conduct
The change of high-precision apparatus, some offset, often allows the hydraulic performance decline of motor, and used method is in stator at this stage
Increase self-clinching point in punching, be secured together by the connection function of self-clinching point, but since self-clinching point is all often convex
The combination with depression points is played, the insulating layer of insulating cement is so destroyed sometimes, causes to connect between stator punching, so as to increase whirlpool
Effect is flowed, therefore is directed to this problem, it would be desirable to which the prior art is reformed.
Utility model content
The purpose of this utility model, which is to provide one kind, can ensure preferably to be connected to become an entirety between stator punching,
And cost is relatively low, the preferable novel stator punching of effect.
What the purpose of this utility model was realized in：Including teeth portion, teeth groove, from catching groove, have yoke portion, wire casing, projecting slot
Mouth, right angle tooth and rotor installing zone, the teeth portion outside are equipped with teeth groove, and teeth groove is equipped with six altogether, and is uniformly arranged on tooth
It is equipped with the outer ledge in portion, on the inside of the teeth groove from catching groove, can be by automatic buckling itself from catching groove, can also the company of utilizing
Extension bar carries out reinforcing fastening, and yoke portion is equipped with the inside of the teeth portion, and wire casing is equipped with the yoke portion, is smooth water droplet on the inside of wire casing
Shape, is equipped with raised notch on the inside of the wire casing, the height of projection at raised notch both ends for stomodaeum it is wide 1/3rd, the yoke portion
Madial wall is equipped with right angle tooth, and yoke portion inner ring is equipped with rotor installing zone, and a diameter of teeth portion of rotor installing zone and yoke portion are wide
Three times of the sum of degree.
Preferably, the teeth portion and yoke portion form an entirety, and integral surface is smooth, polishes, and does not have it
Burr.
Preferably, the corner of the protrusion notch is all cambered design, and the later stage needs to polish by fine sandpaper.
Preferably, the opening of the right angle tooth all points to the center of circle of rotor installing zone.
The utility model is prominent and beneficial compared with prior art to be had the technical effect that：The device is by the way that self-clinching point is arranged on
Teeth groove position on the outside of stator punching, the inner side with teeth groove is close to so that more convenient while self-clinching do insulation processing, together
When on the inside of yoke portion be equipped with small square, can effectively absorb noise, so as to ensure the work identification of motor, reduce motor hair
Heating rate, while the noise of motor work can also be reduced, improve the quality of motor.
Brief description of the drawings
Fig. 1 is the overall structure diagram of the utility model；

Fig. 3 is the wire casing structure schematic diagram of the utility model.
In figure：1st, teeth portion, 2, teeth groove, 3, from catching groove, 4, yoke portion, 5, wire casing, 6, raised notch, 7, right angle tooth, 8, rotor
Installing zone.
Embodiment
The utility model is further described with specific embodiment below in conjunction with the accompanying drawings, referring to Fig. 1-3：
Including teeth portion 1, teeth groove 2, from catching groove 3, yoke portion 4, wire casing 5, raised notch 6, right angle tooth 7 and rotor installing zone 8, institute
State the outside of teeth portion 1 and be equipped with teeth groove 2, teeth groove 2 is equipped with six altogether, and is uniformly arranged on the outer ledge of teeth portion 1, the tooth
The inner side of groove 2 is equipped with from catching groove 3, and reinforcing fastening can also be carried out using connecting rod by automatic buckling itself from catching groove 3,
The inner side of teeth portion 1 is equipped with yoke portion 4, and the teeth portion 1 and yoke portion 4 form an entirety, and integral surface is smooth, polishes,
It is not had burr, quality can be improved, ensure the working stability of motor, improve service life, wire casing is equipped with the yoke portion 4
5, the inner side of wire casing 5 is smooth drops, and the inner side of wire casing 5 is equipped with raised notch 6, and the corner of the protrusion notch 6 is all
For cambered design, and the later stage needs to polish by fine sandpaper, can prevent the raised by coil of turning during high-speed rotation
