Abstract
The utility model discloses an electric machine stator structure, comprising a stator main body formed by riveting n mutually-stacked stacking slices. A mark groove for winding is pressed on the exterior ring surface of each stacking slice and the included angle between the protection of the mark groove of m stacking slices on the axis vertical surface of the stator main body and the protection of the mark groove of residual n-m stacking slices on the axis vertical surface of the stator main body is 180 degree, wherein m=n/2 when n is even number; m=n/2+1/2, when n is odd number and the m stacking slices are continuous stacked on the upper part of the stator main body. The stacking slices are symmetrically distributed and stacked by the 180 degree and the effect of deformation of the stacking slices on the same direction is eliminated after pressing the mark groove and the riveted stator structure has advantages of flattened end surface, good symmetry and no inclining.
Description
Technical field
The utility model relates to motor stator.
Technical background
Motor stator is formed by some lamination stack riveted joints usually, and also dash the labeled slots that the usefulness that rolls off the production line is arranged at the stator outer ring surface, also punching out simultaneously again after the stack of some laminations during the punching out labeled slots, existing lamination is directly riveted joint behind the good labeled slots of punching out, there is a defective in this structure, it is exactly the distortion that some laminations can produce same direction behind the punching out labeled slots, stator out-of-flatness after so just making riveted joint good, tilt condition can appear in end face, influence stator quality, also there is the certain quality skewness in stator itself simultaneously.
The utility model content
Technical problem to be solved in the utility model just provides a kind of motor stator structure, and it is smooth that this stator structure has end face, and symmetry is good, the advantage of tilt condition can not occur.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme: a kind of motor stator structure, comprise stator body, described stator body is made up of the lamination riveted joint of n sheet mutual superposition, every lamination outer ring surface upper punch is shaped on the labeled slots of the usefulness that rolls off the production line, it is characterized in that: wherein the labeled slots of m sheet lamination are 180 degree angles in projection on the stator body axial line vertical plane and the projection of labeled slots on stator body axial line vertical plane that remains n-m sheet lamination, wherein, when n is even number, m=n/2, when n is odd number, m=n/2+1/2.
Described m sheet lamination stack continuously is in stator body top.
The utility model by the stack that distributes of 180 degree angle symmetry, has been eliminated the influence that some laminations behind the punching out labeled slots can produce same direction distortion with lamination, and it is smooth that the stator structure that riveted joint is good has end face, and symmetry is good, the advantage of tilt condition can not occur.
Description of drawings
The utility model will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of the utility model motor stator structure;
Fig. 2 is Fig. 1 vertical view.
Embodiment
As depicted in figs. 1 and 2, be a kind of motor stator structure of the utility model, comprise stator body, described stator body is made up of lamination 1 riveted joint of n sheet mutual superposition, every lamination outer ring surface upper punch is shaped on the labeled slots 2 of the usefulness that rolls off the production line, wherein the labeled slots of m sheet lamination are 180 degree angles in projection on the stator body axial line vertical plane and the projection of labeled slots on stator body axial line vertical plane that remains n-m sheet lamination, wherein, when n is even number, m=n/2, when n was odd number, m=n/2+1/2, described m sheet lamination stack continuously were in stator body top.
Claims (2)
1. motor stator structure, comprise stator body, described stator body is made up of the lamination riveted joint of n sheet mutual superposition, every lamination outer ring surface upper punch is shaped on the labeled slots of the usefulness that rolls off the production line, and it is characterized in that: wherein the labeled slots of m sheet lamination are 180 degree angles in projection on the stator body axial line vertical plane and the projection of labeled slots on stator body axial line vertical plane that remains n-m sheet lamination, wherein, when n is even number, m=n/2, when n is odd number, m=n/2+1/2.
2. motor stator structure according to claim 1 is characterized in that: described m sheet lamination stack continuously is in stator body top.
