Specific embodiment of the present utility model is described in detail below in conjunction with accompanying drawing.It should be appreciated that herein
Described embodiment is merely to illustrate and explained the utility model, is not limited to the utility model.
It should be noted that in the case where not conflicting, the feature in embodiment and embodiment in the utility model can
To be mutually combined.
In the utility model, in the case where not making opposite explanation, the noun of locality such as " upper and lower, top, bottom " used is generally
It is each part mutual alignment either on vertical, vertical or gravity direction for direction shown in the drawings
Relationship description word.
Describe the utility model in detail below with reference to the accompanying drawings and in conjunction with the embodiments.
The utility model provides a kind of stator, reference picture 1, Fig. 3 and Fig. 5, and stator includes stator core 1 and stator winding 2,
Stator tooth 11 of the inner peripheral of stator core 1 formed with multiple circumferentially spaced arrangements, shape between adjacent two stator tooths 11
Into there is stator teeth groove 12, stator winding 2 on stator tooth 11, wherein, stator also includes mouse cage fixing component 3, and mouse cage is solid
Determining component 3 includes the squirrel-cage bar 32 of two end ring 31 of end ring 31 and connection at both ends, the clad type fixed stator winding 2 of end ring 31
Axial end portion.
In the technical scheme, the axial direction two of the clad type fixed stator winding 2 of end ring 31 at the both ends of mouse cage fixing component 3
End, and two end ring 31 are connected by squirrel-cage bar 32, mouse cage fixing component 3 forms integral structure with stator, is arranged such, can
The rigidity of stator is effectively improved, makes stator that there is higher intrinsic frequency, so, can effectively avoid stator that low-frequency vibration occurs and enter
And low frequency noise is produced, be advantageous to improve the usage comfort of user, improve the usage experience of user.In addition, by fixed
Mouse cage fixing component 3 is set on son, also helps and exports the heat that stator winding 2 distributes from stator interior, that is, it is fixed to be advantageous to
The radiating of sub- winding 2, so that the resistance of stator winding 2 reduces, and then improve efficiency.
Wherein, reference picture 3, the end ring face at the axial both ends of mouse cage fixing component 3 should exceed the axially end of stator winding 2
The axial end of winding is all wrapped, is arranged such by end, i.e., the end ring 31 in mouse cage fixing component 3, is advantageous to improve and is determined
The rigidity of son, so as to more effectively reduce noise.
In addition, reference picture 3 and Fig. 4, the radius of the inner peripheral of end ring 31 should be greater than the radius of the inner peripheral of stator core 1,
So, it is possible to increase the yoke portion width of stator core 1, so as to be advantageous to improve the intrinsic frequency of stator, it is fixed more effectively to avoid
Son makes a noise.
Specifically, reference picture 5, mouse cage fixing component 3 should be integrated injection molding part, so, not only can be by the axle of stator winding 2
Coated to end and be fixed on the lower section of end ring 31, but also mouse cage fixing component 3 can be avoided to be come off from stator.In addition, mouse
Cage fixing component 3 is integrally formed in the form of frock injecting glue, and workable and production technology is relatively simple.
In addition, the squirrel-cage bar 32 that two end ring 31 are connected can there are into a variety of appropriate setting forms, such as squirrel-cage bar 32
On the periphery wall of stator core 1 or be interspersed in stator teeth groove 12 etc., no longer enumerate herein.Specifically, mouse cage is solid
Determine component 3 and formed using frock injecting glue, the gap being placed between the periphery wall of the stator in frock its stator core 1 and frock compared with
It is small, colloid flowing is not easy to, i.e., is difficult to be formed complete squirrel-cage bar 32 in the gap location so that the end ring 31 at both ends to be attached,
In addition, the gap between two stator winding 2 in stator teeth groove 12 is relatively large, accordingly, it is preferred that squirrel-cage bar 32 is set
In in stator teeth groove 12, reference picture 2 to Fig. 5, mouse cage fixing component 3 includes the multiple squirrel-cage bars 32 being evenly distributed, squirrel-cage bar
32 are axially interspersed between two stator winding 2 in stator teeth groove 12.
Specifically, for reference picture 3 to Fig. 6, the quantity of squirrel-cage bar 32 should be less than the quantity of stator teeth groove 12.Preferably, mouse cage
The 2/3 of quantity of the quantity of bar 32 not less than 2 and no more than stator teeth groove 12.It is to be appreciated that connection mouse cage fixing component 3
It is integrally formed in the form of frock injecting glue, if the quantity of squirrel-cage bar 32 is very few, is unfavorable for colloid and is flowed into from one end of stator
The other end of stator, and then there is the situation that colloid can not all cover the axial end portion of stator winding 2.Certainly, connect
The quantity of the squirrel-cage bar 32 of the end ring 31 at the both ends of mouse cage fixing component 3 is also unsuitable excessive, within the compressor, two in stator teeth groove 12
Gap between individual winding accounts for the 1/2 of the oil area of whole motor, therefore, between two windings in stator teeth groove 12
Squirrel-cage bar 32 quantity it is excessive, oil spitting amount of compressor can be caused to deteriorate so that compressor efficiency reduce.
In addition, with continued reference to Fig. 3 to Fig. 6, end ring 31 is provided with through-going recess 31A, and through-going recess 31A is not with interting squirrel-cage bar
32 stator teeth groove 12 is axially aligned, so, within the compressor, the stator winding in the stator teeth groove 12 of not interspersed squirrel-cage bar 32
Gap between 2 can be used for oil to circulate, and so as to can ensure that oil spitting amount of compressor does not deteriorate, and then avoid reducing compression function
Effect.
According to another aspect of the present utility model, there is provided a kind of motor, the motor include rotor and according to the utility model
The stator of embodiment.Wherein, rotor is rotatablely arranged at the hollow intracavitary of stator.Due to determining for the utility model embodiment
Son has above-mentioned beneficial technique effect, and therefore, stator in the motor of the utility model embodiment is also with higher intrinsic
Frequency, so as to effectively reduce motor noise, and the mouse cage fixing component 3 being arranged on stator is also beneficial to stator winding 2
Radiating, so, be advantageous to improve motor efficiency.
