Abstract

The utility model is related to technical field of motors, specifically disclose a kind of low noise stator punching, including stator punching ontology, it is characterised in that:The stator punching ontology is equipped with the multiple stator tooths being oriented radially inwards towards the stator punching ontology longitudinal axis, and the tooth top end face of the stator tooth is plane, and the outer of the stator punching ontology is equipped with several sections;It is simple in structure, the torque pulsation of motor can be eliminated, while eliminating vibration noise;Reduce frictional force when being pressed into stator punching, facilitate installation, reduces deformation, the distortion of the caused stator punching in process of press in, avoid the electromagnetism field distortion therefore caused and generate noise.

Description

Low noise stator punching
Technical field
The utility model is related to technical field of motors, and in particular to a kind of low noise stator punching.
Background technology
Stator is the medium that motor carries out electromagnetic conversion, is the Important Components of motor, the structure or flute profile of stator are to electricity Machine performance, which influences the application that huge but traditional stator punching is designed without for low noise, corrective measure.
Utility model content
The purpose of this utility model is to provide a kind of low noise stator punching, simple in structure, can improve motor electromagnetic noise.
Technical solution adopted by the utility model to solve its technical problems is:A kind of low noise stator punching, including it is fixed Sub- punching ontology, it is characterised in that:The stator punching ontology is equipped with towards the stator punching ontology longitudinal axis radially-inwardly The tooth top end face of the multiple stator tooths being orientated, the stator tooth is plane, and the outer of the stator punching ontology is equipped with several Section.
Preferably, the section is parallel with the end face of stator tooth tooth top.
Further, the stator tooth is equipped with 12.
The utility model has the beneficial effects that:It is simple in structure, the torque pulsation of motor can be eliminated, while eliminating vibration and making an uproar Sound;Reduce frictional force when being pressed into stator punching, facilitate installation, reduces the change of the caused stator punching in process of press in Shape, distortion avoid the electromagnetism field distortion therefore caused and generate noise.

Specific implementation mode
The technical issues of in order to keep the utility model solved, technical solution and advantageous effect are more clearly understood, below In conjunction with attached drawing and embodiment, the utility model is further described.
As shown in figure 4, a kind of low noise stator punching of the utility model, including stator punching ontology, stator punching ontology Equipped with the multiple stator tooths 1 being oriented radially inwards towards stator punching ontology longitudinal axis, 11 end face of tooth top of stator tooth 1 is flat Face, and the outer of stator punching ontology is equipped with several sections 2.As preferred embodiment, stator tooth 1 is equipped with 12, and section 2 It is parallel with the end face of 1 tooth top 11 of stator tooth.
As shown in Figure 1,7 end face of tooth top of each stator tooth of tradition 6 is usually concentric cambered surface, outer 8 be it is complete, 11 end face of tooth top of stator tooth 1 is designed as plane by the utility model.Therefore, between the point on permanent magnet 3 and stator tooth 1 away from From that is, motor gas-gap 4, the track formed with the circular motion of permanent magnet 3 are approximately the magnetic field between air gap 4 at the top of parabola Intensity B will be rotated with rotor 5 to be changed in conic section, is changed close to sine wave, is seen Fig. 5-6;The torque pulsation of motor is eliminated, Vibration noise caused by also eliminating therefore.
Moreover, make trimming processing in 1 outer of stator punching ontology, form several sections 2, reduce stator punching ontology 1 with The contact surface of shell reduces frictional force when being pressed into stator punching, facilitates installation, and it is caused fixed in process of press in reduce Deformation, the distortion of sub- punching, avoid the electromagnetism field distortion therefore caused and generate noise, see Fig. 2-3.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all in this practicality Any modifications, equivalent replacements and improvements made by within novel spirit and principle, should all fall the protection in the utility model Within the scope of.
