Description
Technical field
The utility model is related to machine field, and in particular to a kind of stator punching and the asynchronous electricity comprising the stator punching
Machine.
Background technology
Asynchronous machine itself consumes the energy of a part, this part loss of electric machine bag when electric energy is converted to mechanical energy
Include fixed loss, variable loss and stray loss.
Fixed loss is unrelated with load, that includes core loss and mechanical loss；Variable loss is with load change
Change, refer mainly to rotor copper loss (iron loss) and brush loss；Stray loss then includes that bearing friction damage and rotor rotate
Windage damage for causing etc..
In various losses, the iron loss and copper loss of rotor account for very big proportion.
Therefore this area is devoted to the appropriate design of punching, to improve motor operation performance, improves energy conversion efficiency.
The content of the invention
In view of problems of the prior art, the purpose of this utility model is to provide a kind of stator punching and comprising this
The asynchronous machine of stator punching, by appropriate design stator punching and rotor punching, can improve motor operation performance, improve energy
Amount transformation efficiency.
The utility model provides a kind of stator punching of asynchronous machine, and it includes stator tooth and stator yoke, the stator
Multigroup groove is formed between tooth, it is characterised in that the yoke height of every group of groove is approximately equal to constant.
Further, the yoke of first group in multigroup groove is high waits in first constant Hc1, second in multigroup groove
The yoke of group is high to be waited in second constant Hc2, and second constant Hc2 is slightly less than first constant Hc1, and second group of groove
Quantity less than groove total 1/3.
Further, the high ratio with the width of the stator tooth of the yoke of the groove, more than or equal to 4 and is less than or equal to
5。
The utility model also provides a kind of asynchronous machine, including stator and rotor, and the stator is rushed by the above stator
Piece is formed by stacking, and the rotor is formed by stacking by rotor punching.
Further, the ratio of the overall width of the stator tooth and the overall width of the rotor tooth more than or equal to 0.9 and
Less than or equal to 1.1.
Compared with prior art, the utility model is provided stator punching and the asynchronous machine comprising the stator punching,
Have the advantages that：By appropriate design stator punching and rotor punching, motor operation performance can be improved, improve energy
Transformation efficiency.
Description of the drawings
Fig. 1 is the structural representation of the stator punching with rotor punching of the asynchronous machine of one embodiment of the present utility model
Figure.
Specific embodiment
As shown in figure 1, the asynchronous machine of one embodiment of the present utility model, including stator and rotor, stator is by stator
Punching is formed by stacking, and rotor is formed by stacking by rotor punching, and stator punching includes stator tooth and stator yoke, shape between stator tooth
Into multigroup groove, the yoke height of every group of groove is approximately equal to constant.
The yoke of first group in multigroup groove is high to be equal to or approximately equal to first constant Hc1.Because technique needs, make
Outside diameter into stator punching is jagged, makes indivedual groove yoke height be not equal to first constant Hc1.For example illustrate, in multigroup groove
Second group of yoke it is high be equal to or approximately equal to second constant Hc2, and second constant Hc2 is less than the first constant
Hc1, and the quantity of second group of groove less than groove total 1/3 less than first constant Hc1 groove, that is, the yoke height of groove etc.
Total 1/3 of groove is less than in the quantity of second constant Hc2.
The ratio of the yoke high Hc1 and Hc2 of the groove and the width of stator tooth, more than or equal to 4 and less than or equal to 5.
Rotor punching includes rotor tooth, and the overall width of stator tooth is more than or equal to 0.9 with the ratio of the overall width of rotor tooth
And less than or equal to 1.1.
Specifically, said stator punching and rotor punching are applied to into Φ 107,1HP asynchronous machines, stator punching inside/outside
Footpath=107/56 ≈ 1.91.
Stator includes 24 stator tooths, and the width of each stator tooth is 3.0 millimeters, and the yoke of groove is a height of 13.06 millimeters, groove
The ratio of the high width with stator tooth of yoke：
13.06/3≈4.35。
Rotor includes 34 rotor tooths, and the width of each rotor tooth is 2.12 millimeters, the overall width/rotor tooth of stator tooth
The ratio of overall width is：
24*3.0/34*2.12=0.999.
Motor rated power PN is 680W before Optimize magnetic circult, and by above-mentioned Optimize magnetic circult, efficiency by inputoutput test improves 1.2%；
In addition overload no-load power P0 is also accordingly reduced so that overload capacity improves 5%.
Preferred embodiment of the present utility model described in detail above.It should be appreciated that the ordinary skill people of this area
Member just can make many modifications and variations without the need for creative work according to design of the present utility model.Therefore, all this technology necks
Technical staff passes through on the basis of existing technology logic analysis, reasoning or limited reality according to design of the present utility model in domain
Available technical scheme is tested, all should be in the protection domain being defined in the patent claims.
