Abstract
The invention belongs to the field of motor stators, and in particular relates to a motor stator structure. The motor stator structure comprises a stator iron core; the stator iron core is formed by a plurality of stator laminations in a laminating manner; an installation part and a motor end cover installed with the installation part in a matched manner are arranged at two ends of the stator iron core; and thus, the concentricity of the motor stator structure is ensured. The motor stator structure disclosed by the invention has the advantages of being simple in structure, convenient to install, high in concentricity of the end cover and the stator iron core, low in working noise and the like.
Description
Technical field
The present invention relates to motor stator field, particularly relate to a kind of motor stator structure.
Background technology
Traditional motor stator is overrided to form by stator lasmination, and then install screw hole and end cap location and installation by four, during installation, end cap is easily shifted, and concentricity cannot ensure, causes the vibration noise of motor large.The patent No. be CN202197151U patent discloses a kind of stator structure of medium-high voltage alternating current generator, its stator core is overrided to form by several square stator punching, and adjacent two pieces of stator punchings line up polygon-octagonal respectively, composition octangle stator core, the angle space that octangle stator core generates forms air duct.Stator core makes full use of the material at square stator punching four angles, composition octangle stator core, the angle space generated forms air duct, can meet the requirement that the needs that ventilate can meet again mesohigh alternating current machine clearance for insulation, eliminates iron core support muscle of the prior art; The active iron core external diameter of octangle stator core is greater than the active iron core external diameter of existing circular stator iron core simultaneously.This arrangement enhances the utilance of material, reduce production cost, but do not improve mounting structure, installation process is complicated, and the concentricity of end cap and stator cannot ensure, causes the vibration noise of motor very large.
Summary of the invention
The present invention is directed to prior art Problems existing, provide a kind of structure simple, be convenient to install, end cap and stator core concentricity high, the motor stator structure that work noise is little.
The technical solution adopted for the present invention to solve the technical problems is: a kind of motor stator structure, comprise stator core, described stator core is overrided to form by some stator lasminations one, described stator core two ends have installation portion and coordinate with described installation portion the electric motor end cap installed, to guarantee the concentricity of motor stator structure.
Be provided with installation portion at the two ends of stator core, simplify the installation process of stator core, and make the concentricity of the stator core after installing and end cap more accurate, further reduce motor vibration noise in the course of the work.
Further, described installation portion is overrided to form by the some stator lasminations two removing inner core.
Further, described installation portion has endoporus stylobate.
Further, described endoporus stylobate is made up of the inner ring surface of described installation portion and the end side surface of described installation portion.
Further, described electric motor end cap have with described endoporus stylobate with the use of the outer stylobate of end cap.
Further, described electric motor end cap has the outer stylobate of end cap; The outer stylobate of described end cap is the annular projection on end cap and described installation portion (2) contact-making surface.
Further, described installation portion end side surface has screwed hole; Described electric motor end cap have with described screwed hole with the use of butt hole.
The end cap between outer land base that the present invention is covered by the endoporus stylobate on stator core installation portion and respective end positions installation with the use of to stator core, simplify the installation process of stator core, improve the concentricity of end cap and stator core simultaneously, the noise in machine operation process is reduced to some extent.
Accompanying drawing explanation
Fig. 1 is the vertical view of a kind of motor stator structure of the present invention;
Fig. 2 is the sectional view of a kind of motor stator structure of the present invention.
Wherein: 1, stator lasmination, 2, installation portion, 3, screwed hole.
Embodiment
Technical scheme of the present invention is further illustrated by embodiment below in conjunction with accompanying drawing.
As depicted in figs. 1 and 2, a kind of motor stator structure, comprises stator core, and described stator core is overrided to form by some stator lasminations 1, should carry out and iron core does not grind and do not file when core length is measured at iron core cylindrical place.Continue the some stator lasminations two of superposition at stator core two ends and the inner core continuing the stator lasmination two of superposition is removed, forming the installation portion 2 of stator core.Installation portion 2 structure is simple, installs stator installation process is simplified by installation portion 2.End side surface and its inner ring surface of installation portion 2 together constitute endoporus stylobate.
In addition, also comprise with this motor stator structure installation portion 2 with the use of electric motor end cap, electric motor end cap has with endoporus stylobate with the use of the outer stylobate of end cap, the outer stylobate of this end cap is the annular projection on end cap and installation portion 2 contact-making surface.The external diameter of this annular protrusion and the minor diameter fit of endoporus stylobate are arranged, stator core is played to the effect of positioning limit, make the concentricity of stator core and end cap high, avoid the phenomenon that electric motor end cap displacement occurs because of vibration during machine operation, reduce the noise sent because of end cap displacement.
In addition, motor mounting part 2 end side surface has screwed hole 3, electric motor end cap has butt hole, by screw, screwed hole 3 and butt hole, installation portion 2 and electric motor end cap are firmly fixed, prevent stator core and electric motor end cap from because working long hours, inconsistent phenomenon occurring, further reduce operating noise, improve the performance of motor.
It is simple that a kind of motor stator structure of the present invention has structure, is convenient to install, end cap and stator core concentricity high, the advantages such as work noise is little.
