Abstract
A kind of stator the present invention relates to stator laminating structure of motor and its using the punching, stator punching body including strip, the stator punching of strip includes strip yoke portion and in strip yoke portion one side along the equally distributed teeth portion in strip yoke portion, the free ending tool of teeth portion has tooth boot portion, in the strip yoke portion side and teeth portion homonymy and between two adjacent teeth portion dashpot is provided on the offset position of midpoint, dashpot so that strip yoke portion can be with looped-shaped bending, and dashpot is closed into a line during strip yoke portion's looped-shaped bending, the present invention solves the problems, such as leakage field existing for existing strip stator punching, realize Machine automated coiling, and promote winding slot rate, so as to promote motor performance.
Description
Technical field
The present invention relates to motor technologies, are specifically a kind of stator laminating structure of motor and its stator using the punching.
Background technology
Motor stator is generally using whole punching at present, then by punching closed assembly, current this stator laminating structure iron core
Stock utilization is low, and due to the requirement of machine coiling, channel opening need to be larger, and the copper factor of electric machine winding slot is not high, so as to shadow
The performance and cost performance of motor are rung.
Someone devises the stator punching of strip therefore, as notification number is：Punching section described in CN104753198A includes can
The strip yoke portion of bending camber and the length direction along the strip yoke portion are disposed on multiple in the strip yoke portion
Teeth portion, each teeth portion is vertical compared with the strip yoke portion, in one end away from the strip yoke portion of every sub- teeth portion
With tooth boot portion, strip yoke portion is equipped with the spaced multiple dashpots of length direction along the strip yoke portion, dashpot
Between the teeth portion adjacent positioned at two；This structure can be with effectively save magnetic steel material, due to the presence of dashpot, hence directly
The yoke portion of line can be converted into the ring-type of closing, be also convenient for realizing machine coiling；But punching during this structure stator lamination stacking
On dashpot be also alignment, after strip yoke portion looped-shaped bending, since crack is mutually aligned in each layer punching, buffering
Slot will form a crack axially penetrated through after being closed, and electromagnetic field circuit is caused to be obstructed, generates serious leakage field, so as to influence
The properties of motor.
The content of the invention
A kind of stator it is an object of the invention to provide stator laminating structure of motor and its using the punching, strip yoke portion
And the teeth portion vertical with yoke portion, the dashpot in strip yoke portion between adjacent teeth portion are set for biasing, such punching exists
Dashpot during stacking between adjacent two layers punching is mutual dislocation, therefore electromagnetic field circuit is unobstructed so that bends to annulus
There is no the phenomenon that leakage field, there are serious leakage fields so as to overcoming existing strip stator punching to ask the stator core of shape
Topic, so as to promote the properties of motor.
Following technical scheme is used to achieve the above object：
A kind of stator laminating structure of motor and its stator using the punching, the stator punching body including strip, strip
Stator punching include strip yoke portion and in teeth portion of the strip yoke portion one side along the vertical uniform distribution in strip yoke portion, teeth portion it is another
End has tooth boot portion, it is characterised in that：In the strip yoke portion one side and the midpoint offset position between two adjacent teeth portion
On be provided with dashpot, dashpot causes strip yoke portion can be with looped-shaped bending, and when strip yoke portion bends to annular shape is delayed
Jet-bedding is closed into a line.
Teeth portion is alignd when the stator punching is stacked and dashpot misplaces so that the dashpot between adjacent two layers punching
Mutual dislocation.
The present invention is set compared with traditional technical bias dashpot, stator in lamination process, adjacent two layers
It is mutual dislocation to buffer groove location, and such punching is when bending to circular stator core, the combination of dashpot formation
Seam is mutual dislocation, therefore electromagnetic field circuit is unobstructed, so as to avoid serious leakage field existing for existing strip stator punching
Problem, and there is the saving material of strip stator punching, be suitble to Machine automated coiling, copper factor high, so as to big
The big properties for improving motor.

Specific embodiment
As shown in figures 1 to 6, a kind of stator laminating structure of motor and its stator using the punching, the stator including strip
Punching body 1, the stator punching 1 of strip include strip yoke portion 11 and equally distributed along strip yoke portion in strip yoke portion one side
Teeth portion 12, the other end of teeth portion have tooth boot portion 13, with 12 homonymy of teeth portion and adjacent positioned at two in 11 side of strip yoke portion
Dashpot 2 is provided between teeth portion on the offset position of midpoint, dashpot 2 allows strip yoke portion 11 to bend to annular shape, and
And dashpot 2 can be closed completely during strip yoke 11 looped-shaped bending of portion；
Teeth portion is alignd when the stator punching is stacked and dashpot misplaces so that the dashpot 2 between levels punching is mutual
Dislocation.
Dashpot 2 is biased setting by the present invention, mutually wrong in the dashpot 2 of stator stack added-time adjacent two layers stator punching
Position, thus when bending to annular shape dashpot 2 be closed bonding crack be also dislocation, efficiently solve in existing punching due to
Leakage field problem caused by the overlapping of buffering groove location up and down, while the punching with strip is suitble to machine automatic winding, winding efficiency
It is high with copper factor, so as to greatly promote the properties of motor.
Mainly for inner rotor core stator core in above-mentioned structure, in addition as shown in Figure 7,8, the present invention can also incite somebody to action
Dashpot and teeth portion are located at the both sides in strip yoke portion, and the stator core knot of outer rotor will be formed after such stator punching bending
Structure.
