Embodiment 1
Referring to Fig. 1 and Fig. 2, the utility model embodiment provides a kind of hidden salient-pole machine stator structure, the hidden salient-pole machine
Stator structure includes mutually interference fit assembling connected external stator 1 and inner stator 2, and external stator 1 is that inner chamber side number is 2P or 3P
Polygonal ring shape structure, wherein P be motor pole number.Preferably, the external stator 1 of the present embodiment can be inner chamber side number be 2P just
Polygon-shaped structure and be easy to manufacture.Cyclic structure provided with perforation 23 centered on the inner stator 2 of motor, the perforation 23 can be electric
The rotor of machine is passed through.The outer peripheral edge of inner stator 2 is uniformly distributed and the radial inner stator stretched out provided with circumferentially ring-type
Two adjacent inner stator teeth 22 are connected by tooth 22, the tooth root bottom of two adjacent inner stator teeth 22 provided with arch bridge portion 21.This
The arch bridge portion 21 of embodiment is the narrow arch bridge-like structure in the wide two ends in middle part, and arch bridge portion 21 is round and smooth to smooth out towards the base of perforation 23
Curve, while be additionally provided with the through hole 213 for cutting the adjacent internal magnetic field of inner stator tooth 22 inside arch bridge portion 21, and this is logical
Do not intersect with the top margin 211 in arch bridge portion 21 and base 212 in hole 213.
The through hole 213 of the present embodiment is toroidal hole, and through hole 213 and the top margin 211 of arch bridge portion 21 most short distance are
0.2mm, through hole 213 and the base 212 of arch bridge portion 21 most short distance are 0.2mm, are also interspersed with and through hole inside through hole 213 in addition
The Teflon inserted block that 213 edges match.
In the present embodiment, the arch bridge portion 21 for being arranged at the tooth root bottom of two neighboring inner stator tooth 22 is narrow in the wide two ends in middle part
Structure, and be arranged at the through hole 213 at the middle part of arch bridge portion 21 and do not intersect with the top margin 211 in arch bridge portion 21 and base 212, this
Sample causes the top margin 211 in arch bridge portion 21 and base 212 not to form the arch ring with opening, when inner stator 2 passes through small shrink
When in amount assembling press-in external stator 1, the position of arch bridge portion 21 of inner stator 2 will not also turn into the position of rigidity fragility the most, so that
When ensureing the press-in external stator 1 of inner stator 2, the squeeze force that two adjacent inner stator teeth 22 are imposed to arch bridge portion 21 is not easy to make
The perforation 23 inside inner stator 2 is obtained to be deformed by circle.Although in addition, setting through hole 213 certain in the inside in arch bridge portion 21
In degree, it is provided with the arch ring of opening relative to prior art and is decreased in reduction magnetic loss ability, but this practicality is new
The technical scheme of type partially removes magnetic loss ability by setting through hole 213 at the middle part of arch bridge portion 21, to reduce inner stator 2 and is used as generation
Valency, can improve the overall assembling rigidity and the reduction assembling scrappage of inner stator 2 of inner stator 2.In addition, the through hole of the present embodiment
213 and the top margin 211 of arch bridge portion 21 most short distance are 0.2mm, and through hole 213 and the base 212 of arch bridge portion 21 most short distance are
0.2mm, so that through hole 213 and the top margin 211 of arch bridge portion 21 and base 212 are non-intersect, can either so ensure this implementation
The effect of the inner stator reduction magnetic loss of inner stator 2 and the prior art of example is substantially consistent, and including enabling to through hole 213
Certain rigidity is kept during stator 2 and external stator 1 mutually interference fit, it is to avoid perforation 23 is deformed.
Preferably, Teflon inserted block is interspersed with inside the through hole 213 of the present embodiment, when the crimping of multiple silicon steel sheets of inner stator 2
After assembly, insertion is mutually furnished with Teflon inserted block with the endoporus edge of through hole 213 inside through hole 213.Because Teflon inserted block is tool
There is certain degree of hardness and be not easy the insulator that is compressed, after Teflon inserted block is inserted in through hole 213, Teflon inserted block will not be with
The silicon steel sheet magnetic conduction of inner stator 2, mutually extrudes after being integrally formed with through hole 213, further improves the rigidity in arch bridge portion 21, so
When inner stator 2 is pressed into 1 inside of external stator, the integrally-built rigidity of inner stator 2 is further enhanced relative to prior art, from
And the scrappage after the elastic conjunction of inner stator 2 is further reduced, for Reducing Cost in Enterprises, improve motor product quality tool
It is significant.
Embodiment 2
Referring to Fig. 3, the present embodiment is same as Example 1 in addition to following characteristics：Being arranged at the through hole in the middle part of arch bridge portion 21 is in
Equilateral triangle, and 23 centers of the top of the horn direction perforation of the through hole 213 in equilateral triangle.
In the present embodiment in equilateral triangle through hole 213 the top of the horn toward 23 centers of perforating, the present embodiment is in equilateral
The through hole 213 of Three-legged shape and the top margin 211 of arch bridge portion 21 most short distance are 0.5mm, through hole 213 and the base 212 of arch bridge portion 21
Most short distance is 0.5mm, so that through hole 213 and the top margin 211 of arch bridge portion 21 and base 212 are non-intersect, so can
Enough ensure that the inner stator 2 of the present embodiment is substantially consistent with the inner stator 2 of the prior art effect for reducing magnetic loss, and can make
Obtain through hole 213 and keep certain rigidity during inner stator 2 and the mutually interference fit of external stator 1, it is to avoid perforation 23 is deformed.
The thickness reduction for so causing the bottom of arch bridge portion 21 to be used to mitigate magnetic loss close to the position of perforation 23, so that this
Embodiment arch bridge portion 21 mitigate magnetic loss ability it is as far as possible close with prior art, and equilateral triangle through hole 213 in structure
On be to tend to relative rock-steady structure, during press-in 1 inside of external stator of inner stator 2, the arch bridge portion 21 of inner stator 2 is also less likely to occur to become
Shape.
Meanwhile, the Teflon inserted block matched therewith, the spy of triangular prism column are inserted in the inside of through hole 213 of equilateral triangle shape
Fluorine dragon inserted block causes the rigidity of through hole 213 further to be lifted, and during the such press-in of inner stator 21 inside of external stator, is more not easy hair
Change shape.
Preferred embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited,
It is every under design of the present utility model, the equivalent structure transformation made using the utility model specification and accompanying drawing content, or
Directly/be used in other related technical fields indirectly and be included in scope of patent protection of the present utility model.
