Abstract
The invention discloses a motor stator structure which comprises a stator body. The stator body is formed by riveting n mutually laminated lamination membranes, and a marker groove for a downline is punched on the outer ring surface of each lamination membrane, wherein an included angle of 180 degrees is formed between the projections of the marker grooves of the m lamination membranes on the vertical surface of a stator body axis and the projections of the marker grooves of the rest (n-m) lamination membranes on the vertical surface of the stator body axis, m=n/2 when n is an even number and m=n/2+1/2 when n is an odd number, and the m lamination membranes are continuously laminated at the upper part of the stator body. By symmetrically distributing and laminating the lamination membranes at 180 degrees, the invention eliminates the influence of deformation in the same direction caused by the plurality of lamination membranes after the marker grooves are punched, and the riveted stator structure has the advantages of smooth end surface and good symmetry without inclination state.
Description
Technical field
The present invention 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.
Summary of the invention
Technical problem to be solved by this invention 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 present invention 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 present invention by the stack that distributes of 180 degree angle symmetry, has 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 invention will be further described below in conjunction with accompanying drawing:
Fig. 1 is the structural representation of motor stator structure of the present invention;
Fig. 2 is Fig. 1 vertical view.
Embodiment
As depicted in figs. 1 and 2, be a kind of motor stator structure of the present invention, 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.
