Abstract
The punching of a kind of motor shaped groove type stator, comprise stator punching body, four angles of this stator punching body respectively offer positioning through hole, in described stator punching body inner circle, offer each asymmetric stator punching groove mutually, the joining of the centre symmetry line of all stator punching grooves departs from the stator punching body inner circle center of circle, on a side of described stator punching body, is arranged with contact hypotenuse.Three stator punching bodies can push laminating mutually, and the contact hypotenuse of one of them stator punching body can overlap between two with the hypotenuse that contacts of two other stator punching body.The utility model plays larger effect for the optimization of magnetic flux distribution and magnetic circuit, thereby the motor Energy Efficiency Ratio of applying this stator punching is obviously reduced, and, design due to the contact hypotenuse of punching one side, makes three punchings bonded to each other, has reduced the longitudinal length of processing iron plate, thereby the material of saving, especially large-scale production is comparatively obvious, therefore, has stronger generalization.
Description
Technical field
The utility model discloses the punching of a kind of motor shaped groove type stator.
Background technology
Motor stator is to consist of coil and stator core, and stator core is that the directional cumulation along axle forms by a plurality of stator punchings.
The design of stator punching at present adopts stator punching inner circle uniform ring to be provided with stator punching groove mostly, and the intersection point of the center line of groove overlaps with the stator punching inner circle center of circle, this design does not reach the optimized effect of magnetic circuit, Energy Efficiency Ratio is relatively low, and the design of the complete circle of stator punching or rectangle, causes the waste of lot of materials.Therefore, this case and giving birth to.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of magnetic circuit optimization, Energy Efficiency Ratio is low and motor shaped groove type stator punching that can larger material-saving material.
The utility model technical scheme adopting of dealing with problems is:
The punching of a kind of motor shaped groove type stator, comprise stator punching body, four angles of this stator punching body respectively offer positioning through hole, in described stator punching body inner circle, offer each asymmetric stator punching groove mutually, the joining of the centre symmetry line of all stator punching grooves departs from the stator punching body inner circle center of circle, on a side of described stator punching body, is arranged with contact hypotenuse.
Three stator punching bodies can push laminating mutually, and the contact hypotenuse of one of them stator punching body can overlap between two with the hypotenuse that contacts of two other stator punching body.
The beneficial effects of the utility model are: the design of each asymmetric flute profile of the present utility model, and the center line intersection point of flute profile departs from the design in the punching inner circle center of circle, for the optimization of magnetic flux distribution and magnetic circuit, play larger left and right, thereby the motor Energy Efficiency Ratio of applying this stator punching is obviously reduced, and the design due to the contact hypotenuse of punching one side, make three punchings bonded to each other, reduced the longitudinal length of processing iron plate, thereby the material of saving, especially large-scale production is comparatively obvious, therefore, there is stronger generalization.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation;

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1, the utility model provides the punching of a kind of motor shaped groove type stator, comprise stator punching body 1,1 four angles of this stator punching body respectively offer positioning through hole 2, in described stator punching body 1 inner circle, offer each asymmetric stator punching groove 3 mutually, the joining of the centre symmetry line of all stator punching grooves 3 departs from the stator punching body 1 inner circle center of circle, is arranged with contact hypotenuse 4 on a side of described stator punching body 1.
Three stator punching bodies 1 can push laminating mutually, and the contact hypotenuse 4 of one of them stator punching body 1 can overlap between two with the hypotenuse 4 that contacts of two other stator punching body 1.
The design of each asymmetric flute profile of the present utility model, and the center line intersection point of flute profile departs from the design in the punching inner circle center of circle, for the optimization of magnetic flux distribution and magnetic circuit, play larger effect, thereby the motor Energy Efficiency Ratio of applying this stator punching is obviously improved, and, design due to the contact hypotenuse 4 of punching one side, make three punchings bonded to each other, reduced the longitudinal length of processing iron plate, thereby the material of saving, especially large-scale production is comparatively obvious, therefore, has stronger generalization.
The above is only the preferred embodiment of the present invention; should be understood that; for those skilled in the art; under the premise without departing from the principles of the invention; can also carry out some improvement and modification to the present invention, these improvement and modification also fall in the protection range of the claims in the present invention.
Claims (2)
