Abstract
The utility model provides a motor rotor shaft comprising two rotating shafts and a stator iron core. The rotating shafts are connected at two ends of the stator iron core. The peripheral surface of the stator iron core is provided with a plurality of large and small stator teeth. The end face of the stator iron core is provided with a circular groove extending along the circumferential direction, and the circular groove is internally provided with a plurality of round holes in a circular array. According to the stator iron core on the rotor shaft, in the condition of not increasing the thickness of the iron core, the shape, width and depths of the tooth and the groove are changed, the efficiency of the motor is raised, and compared with a traditional stator iron core, the number of windings is reduced.
Description
Technical field
The utility model relates to a kind of armature spindle of motor, especially a kind of rotor axis of electric with stator core.
Background technology
Motor refers to realize electric energy conversion or a kind of calutron that transmits according to the law of electromagnetic induction, comprises stator and rotor, and wherein, stator comprises the winding that stator core and coil form, coil by the opening on stator core in the winding slot of stator core.The manufacture method of traditional stator, for first to use the circular punching of mould punching with winding slot, then laminates circular punching the formation stator core, then uses special interiorly around the machine coiling, and it is low that this kind method is made stator core efficiency, and the cost cost is high.
In order to improve stock utilization and stator speed of production, people attempt stator core is divided into several profile of tooth unit, after on single profile of tooth unit, coil being installed, again the profile of tooth unit splicing is formed stator together, this kind stator core yoke section is narrower to be not suitable in the comparatively complicated mechanism of radial design, can only make simple Mosaic face, integral body can not mutually fasten and need tooling device shaping pressurize, assembly unit is made very inconvenient, and easily dislocation between Mosaic face, cause leakage field excessive, affect the overall performance of motor.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of rotor axis of electric, stator core on this armature spindle is not in the situation that increase shape, width and the tooth of iron core thickness change tooth, the degree of depth of groove, improved the efficiency of motor, compare traditional stator core, reduced the number of turn of winding.
In order to solve existing technical problem, the technical solution adopted in the utility model is: a kind of rotor axis of electric, comprise two rotating shafts and stator core, rotating shaft is connected to the two ends of stator core, the side face of described stator core is provided with a plurality of large and small stator tooths, the end face of stator core is provided with the circular recess that extends along circumferentially, is provided with the circular hole that a plurality of circular array are arranged in this circular recess.
Above-mentioned a kind of rotor axis of electric, the junction of described large stator tooth and little stator tooth is provided with shallow stator slot, and the junction of adjacent little stator tooth is provided with dark stator slot.
Above-mentioned a kind of rotor axis of electric, described large and small stator tooth integral body is stepped tooth, and nearly yoke end tooth shape is wide, and nearly inner circle end tooth shape is narrow.
Above-mentioned a kind of rotor axis of electric, described little stator tooth has two kinds of shapes, and the little stator tooth that is clipped between two dark stator slots is wide, symmetrical, and the little stator tooth that is clipped between dark stator slot and shallow stator slot is not wide, asymmetric heteromorphic teeth.
Above-mentioned a kind of rotor axis of electric, described bottom land dark, shallow stator slot is circular-arc.
Above-mentioned a kind of rotor axis of electric, described rotating shaft and stator core are integral pieces.
Above-mentioned a kind of rotor axis of electric, described large and small stator tooth is evenly arranged on the side face of stator core, and the quantity of large stator tooth is 4, and the quantity of little stator tooth is 24.
The beneficial effects of the utility model are: the stator core on this armature spindle in the situation that do not increase shape, width and the tooth that iron core thickness changes tooth, the degree of depth of groove, has improved the efficiency of motor, compares traditional stator core, has reduced the number of turn of winding.

Embodiment
For making, architectural feature of the present utility model and the effect reached are had a better understanding and awareness, in order to preferred embodiment and accompanying drawing, coordinate detailed explanation, be described as follows:
As shown in Figure 1 and Figure 2, a kind of rotor axis of electric, comprise two rotating shafts 1 and stator core 2, rotating shaft 1 is connected to the two ends of stator core 2, the side face of stator core 2 is provided with a plurality of large stator tooths 21 and little stator tooth 22, the end face of stator core 2 is provided with the circular recess 23 that extends along circumferentially, is provided with the circular hole 24 that a plurality of circular array are arranged in this circular recess 23.
The junction of large stator tooth 21 and little stator tooth 22 is provided with shallow stator slot 25, and the junction of adjacent little stator tooth 22 is provided with dark stator slot 26.
The bottom land of dark stator slot 26 and shallow stator slot 25 is circular-arc.
In the utility model, rotating shaft 1 and stator core 2 are integral pieces.
In Fig. 2, large stator tooth 21 and little stator tooth 22 are evenly arranged on the side face of stator core 2, the quantity of large stator tooth 21 is 4, and the quantity of little stator tooth 22 is 24,, according to the actual conditions in work, can change the quantity of large stator tooth 21 and little stator tooth 22.
The stator slot of the stator core of this armature spindle part adopts the forming cutter work in-process layering processing method of milling in the heart, mills to process progressively moulding, milling width 14.8 minutes for 3 times, milling spacing 11, the degree of depth reaches 74.9, and length reaches 322, effectively avoids the distortion of product in the course of processing; Dark in milling depth, forming surface quantity is many, in the closely spaced situation of forming surface and forming surface, can effectively avoid the product bulk deformation.
