Abstract
The utility model belongs to the motor stator field specifically is a structure of motor stator. A structure of motor stator, includes stator core, stator core is formed by a batch of pressure of a plurality of stator lamination, the stator core both ends have the installation department and with the motor end cover of installation department cooperation installation to ensure structure of motor stator's concentricity. The utility model relates to a structure of motor stator has simple structure, the installation of being convenient for, and the end cover is high with the stator core concentricity, advantages such as work small in noise.
Description
Technical field
The utility model relates to motor stator field, relates in particular to a kind of motor stator structure.
Background technology
Traditional motor stator is overrided to form by stator lasmination, then by four, screw hole and end cap location and installation is installed, and when installation, end cap is easily shifted, and concentricity cannot ensure, causes the vibration noise of motor large. The patent No. is that the patent of CN202197151U discloses a kind of stator structure of medium-high voltage alternating current generator, its stator core is overrided to form by several square stator punchings, and adjacent two stator punchings are lined up respectively polygon-octagonal, composition octagonal stator core, the angle space that octagonal stator core generates forms ventilating duct. Stator core makes full use of the material at four angles of square stator punching, composition octagonal stator core, the angle space generating forms ventilating duct, can meet ventilation needs and can meet again the requirement of mesohigh alternating current generator clearance for insulation, has saved the muscle that supports unshakable in one's determination of the prior art; The active iron core external diameter of octagonal stator core is greater than the active iron core external diameter of existing circular stator core simultaneously. This structure has improved the utilization rate of material, has reduced production cost, but mounting structure is not improved, installation process complexity, and the concentricity of end cap and stator cannot ensure, causes the vibration noise of motor very large.
Utility model content
The problem that the utility model exists for prior art, provides a kind of simple in structure, is convenient to install, and end cap and stator core concentricity are high, the motor stator structure that work noise is little.
The utility model solves the technical scheme that its technical problem adopts: 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 the electric motor end cap of installing with described installation portion, to guarantee the concentricity of motor stator structure.
Two ends at stator core are provided with installation portion, have simplified the installation process of stator core, and stator core and the concentricity of end cap after making to install is more accurate, has further reduced motor vibration noise in the course of the work.
Further, described installation portion is overrided to form by some stator lasminations two of 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 has the outer stylobate of the end cap being used in conjunction with described endoporus stylobate.
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 has the butt hole being used in conjunction with described screwed hole.
The outer stylobate of end cap that the utility model covers by the endoporus stylobate on stator core installation portion and respective ends is used in conjunction with stator core is positioned to installation, 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.
Brief description of the drawings
Fig. 1 is the top view of a kind of motor stator structure of the utility model;
Fig. 2 is the sectional view of a kind of motor stator structure of the utility model.
Wherein: 1, stator lasmination, 2, installation portion, 3, screwed hole.
Detailed description of the invention
Further illustrate the technical solution of the utility model below in conjunction with accompanying drawing and by detailed description of the invention.
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, and core length should carry out at iron core cylindrical place while measurement and iron core does not grind and do not file. Continue the some stator lasminations two of stack at stator core two ends and the inner core of the stator lasmination two that continues stack is removed, forming the installation portion 2 of stator core. Installation portion 2 is simple in structure, by installation portion 2, stator is installed installation process is simplified. The end side surface of installation portion 2 and its inner ring surface have formed endoporus stylobate jointly.
In addition, also comprise the electric motor end cap being used in conjunction with this motor stator structure installation portion 2, have the outer stylobate of the end cap being used in conjunction with endoporus stylobate on electric motor end cap, the outer stylobate of this end cap is the annular projection on end cap and installation portion 2 contact-making surfaces. The internal diameter of the external diameter of this annular protrusion and endoporus stylobate is equipped with, stator core is played to the effect of positioning limit, make the concentricity of stator core and end cap high, while avoiding because of machine operation there is the phenomenon that electric motor end cap is shifted in vibration, has reduced because of the end cap noise sending that is shifted.
In addition, in motor mounting part 2 end side surface, there is screwed hole 3, on electric motor end cap, there is butt hole, by screw, screwed hole 3 and butt hole, installation portion 2 and electric motor end cap are firmly fixed, prevent that stator core and electric motor end cap from inconsistent phenomenon occurring because working long hours, further reduce operating noise, improved the performance of motor.
The advantages such as a kind of motor stator structure of the utility model has simple in structure, is convenient to install, and end cap and stator core concentricity are high, and work noise is little.
