Description
Technical field
The present invention relates to a kind of three-phase Circular Winding stators that interior outer teeth groove quantity is equal.
Background technique
Stator core is the important component of motor, the interior outer teeth groove quantity of existing stator core not phase mostly
Deng, and internal spline is also opened up from the outer ring of stator, causes loop coil in coiling, cannot with the Circular Windings of other phases into
Row is dielectrically separated from well；The uniformity of groove is poor, is unfavorable for ventilation and heat；And existing stator iron core tooth slot number is less,
Causing tooth socket opening larger, keeps it small with shell contact area, heat dissipation performance is poor, and iron core outer toothed portion magnetic conductive area is insufficient,
Increase electric machine iron core loss.
Summary of the invention
A kind of three-phase ring that interior outer teeth groove quantity is equal is provided the invention aims to overcome the deficiencies in the prior art
Shape wound stator.
In order to achieve the above objectives, the technical solution adopted by the present invention is that: a kind of three-phase that interior outer teeth groove quantity is equal annular
Wound stator includes stator body, is provided with multiple outer teeth grooves and multiple internal splines on stator body, outer teeth groove and internal spline
Quantity is equal, and outer teeth groove is provided with the outer ring of stator body, and internal spline is provided with the inner ring of stator body, and outer teeth groove is transversal
Face area is greater than the cross-sectional area of internal spline.
Preferably, the position of multiple outer teeth grooves and multiple internal splines corresponds, corresponding outer teeth groove with it is interior
Tooth socket common centerline.
Preferably, the outer teeth groove and the quantity of internal spline are 24-48, and the multiple for being 3.
Preferably, the cross-sectional area of the outer teeth groove is not less than 1.5 times of the cross-sectional area of internal spline.
Due to the application of the above technical scheme, compared with the prior art, the invention has the following advantages:
The three-phase Circular Winding stator of this programme, interior outer teeth groove quantity is equal, and internal spline is opened up from the inner ring of stator, makes annular
Coil is preferably dielectrically separated from coiling with the Circular Winding of other phases；Outer groove area is greater than inside groove area, and groove
Uniformity it is good, be conducive to ventilation and heat；Iron core teeth slot number is more, and intensive tooth socket can design lesser opening, increases it
With the contact area of shell, keep its heat conducting and radiating performance more preferable, enhances stator heat-sinking capability；And iron core outer toothed portion magnetic conduction face
Product increases, and reduces stator core flux density, that is, reduces electric machine iron core loss.

Technical scheme of the present invention is further explained with reference to the accompanying drawing:
Attached drawing 1 is a kind of Facad structure signal of three-phase Circular Winding stator that interior outer teeth groove quantity is equal of the present invention
Figure；
Attached drawing 2 is a kind of stereochemical structure signal of three-phase Circular Winding stator that interior outer teeth groove quantity is equal of the present invention
Figure；
Attached drawing 3 is the schematic diagram after a kind of three-phase Circular Winding stator winding that interior outer teeth groove quantity is equal of the present invention.
Specific embodiment
Below in conjunction with the accompanying drawings and specific embodiment, the present invention is described in further details.
As shown in Figure 1-3, the three-phase Circular Winding stator that a kind of interior outer teeth groove quantity of the present invention is equal, comprising fixed
Sub- ontology 1 is provided with multiple outer teeth grooves 2 and multiple internal splines 3 on stator body 1, and outer teeth groove 2 is equal with the quantity of internal spline 3,
And multiple outer teeth grooves 2 and the position of multiple internal splines 3 correspond, i.e., corresponding outer teeth groove 2 and 3 common center of internal spline
Line.
The outer teeth groove 2 is provided with the outer ring of stator body 1, and internal spline 3 is provided with the inner ring of stator body 1, and external tooth
The cross-sectional area of slot 2 is not less than 1.5 times of the cross-sectional area of internal spline 3.
The outer teeth groove 2 and the quantity of internal spline 3 are 24-48, and the multiple for being 3, in figure for 24.
In the present solution, interior outer teeth groove quantity is equal, and internal spline is opened up from the inner ring of stator, makes loop coil in coiling
When, it is preferably dielectrically separated from the Circular Winding of other phases.
Outer groove area is greater than inside groove area, and the uniformity of groove is good, is conducive to ventilation and heat.
Iron core teeth slot number is 24-48, it might even be possible to more, intensive tooth socket can design lesser tooth socket opening,
The contact area for increasing iron core and shell, keeps its heat conducting and radiating performance more preferable.
The iron core outer toothed portion magnetic conductive area of this structure increases, and reduces stator core flux density, reduces electric machine iron core loss；
