Description
Technical field
The present invention relates to technical field of motors, in particular to a kind of stator and motor.
Background technology
Frequency conversion motor of the prior art typically can be offered flux at rotor 1 ' and arrange groove 2 ', as it is shown in figure 1, flux is whole
Reason groove 2 ' position be typically all at rotor magnetic steel groove 3 ' by outer radius, but motor efficiency require more and more higher, magnet steel groove
Design the most relatively more and more less near the usable area between rotor diameter side, magnet steel groove and rotor diameter, open
If it is higher to the mechanical property requirements of stalloy that flux arranges groove, it is desirable to making type is higher, once has slightly impulse force the most right, can lead
Cause the deformation of magnet steel groove and magnet steel cannot be assembled.In sum, motor of the prior art is offered flux and arranges the manufacture difficulty of groove
Degree height, production efficiency is low.
Summary of the invention
The embodiment of the present invention provides a kind of stator and motor, to solve prior art is opened in motor of the prior art
If the manufacture difficulty that flux arranges groove is high, the low problem of production efficiency.
For solving above-mentioned technical problem, the invention provides a kind of stator, including stator core, stator core has many
The individual stator teeth circumferentially arranged, each stator teeth is provided with flux and arranges groove.
Further, flux arranges the implant within groove is air.
Further, it is A that all fluxs arrange the cross-sectional area sum of groove, and the area of stator core cross section is B；Its
In, A ＜ (0.1 × B).
Further, the quantity arranging flux arrangement groove in each stator teeth is multiple.
Further, it is three that the flux arranged in each stator teeth arranges groove, and three fluxs arrange groove and are arranged side by side.
Further, it is three that the flux arranged in each stator teeth arranges groove, and three fluxs arrange groove and mutually stagger
Arrange.
Further, it is two that the flux arranged in each stator teeth arranges groove, and two fluxs arrange groove along stator ferrum
The circumference of core is arranged side by side.
According to another aspect of the present invention, it is provided that a kind of motor, including stator, stator is above-mentioned stator.
Application technical scheme, flux arranges the higher hamonic wave acting as eliminating motor gas-gap magnetic close of groove and contains
Amount, flux arranges groove can arrange magnetic line of force running orbit, makes the magnetic line of force increase flex point, path lengthening, thus realizes eliminating height
Subharmonic.The technical program arranges groove by offering number of times on stator core, by coordinating between stator with rotor, equally
Realize flux and arrange the effect of groove, rotor structure then need not offer flux and arrange groove, so change magnetic in prior art
Bundle arranges the structure situation that groove is opened on rotor core, owing to being opened on the stator teeth of stator core, so makes magnetic
The space that bundle arrangement groove can select is bigger, thus the most just reduces flux and arrange the manufacture difficulty of groove, whole owing to offering flux
The difficulty of reason groove is low, moreover it is possible to improving production efficiency further.

Detailed description of the invention
With specific embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings, but not as the limit to the present invention
Fixed.
According to embodiments of the invention, it is provided that a kind of stator being applicable in motor, the stator of the present embodiment and rotor
Coordinating, shown in Figure 2, stator includes stator core 10, and stator core 10 has multiple stator teeth circumferentially arranged
11, each stator teeth 11 is provided with flux and arranges groove 12, each stator teeth 11 can have flux arrange groove or
Multiple fluxs arrange groove.
Flux arranges the higher harmonic content that elimination motor gas-gap magnetic is close that act as of groove, and flux arrangement groove can arrange magnetic
Line of force running orbit, makes the magnetic line of force increase flex point, path lengthening, thus realizes Eliminate highter harmonic.The technical program is passed through
Offer number of times on stator core and arrange groove, by coordinating between stator with rotor, realize flux equally and arrange the effect of groove, turn
Then need not offer flux in minor structure and arrange groove, the structure of rotor 20 sees Fig. 3, so changes flux in prior art whole
The structure situation that reason groove is opened on rotor core, owing to being opened on the stator teeth of stator core, so makes flux whole
The space that reason groove can select is bigger, thus the most just reduces flux and arrange the manufacture difficulty of groove, arranges groove owing to offering flux
Difficulty low, moreover it is possible to further improving production efficiency.
Further, flux arranges the implant within groove 12 is air.Flux arranges groove can change magnetic line of force traveling
Route and direction, be air because flux arranges the inside of groove, is equivalent to cut off magnetic line of force path, makes magnetic line of force increase of having to turn
Point slightly changes direction, thus reduces air gap flux density higher hamonic wave.
It is A that all fluxs arrange cross-sectional area (cross section in the stator somewhere) sum of groove 12, and stator core 10 is transversal
Face area (existing together mutually with the cross section in stator somewhere, upper place) is B；Wherein, A ＜ (0.1 × B).The multiple fluxs offered arrange groove
Cross-sectional area be respectively S1, S2, S3 to Sn, A=S1+S2+S3 ...+Sn=Σ S, Σ S ＜ B*10%, by set magnetic
Bundle arranges the area of groove 12, with ensure that stator teeth magnetic is close will not be too high.
Seeing Fig. 2, the quantity arranging flux arrangement groove 12 in each stator teeth 11 is multiple.In the present embodiment, often
It is three that the flux arranged in individual stator teeth 11 arranges groove 12, and three fluxs arrange groove 12 and are arranged side by side, in the present embodiment,
The shape that three fluxs arrange groove 12 cross sections is identical, and spacing distance between any two is identical.
As flux arranges the shape of groove 12 can be different, can also have any different in position, but the effect reaching to arrange is
's.In another embodiment as shown in Figure 4, it is less that middle flux arranges groove 12, and the flux arrangement groove 12 of centre is transversal
The shape in face is different from other two.
In another embodiment as shown in Figure 5, it is shown that another shape of flux arrangement groove 12, specifically,
It is three that the flux arranged in each stator teeth 11 arranges groove 12, and three fluxs arrange grooves 12 and mutually stagger setting.Stagger and set
Three fluxs put arrange that groove 12 is more convenient to be processed.In an embodiment as shown in Figure 6, in each stator teeth 11
It is two that the flux arranged arranges groove 12, and two fluxs arrange groove 12 and are arranged side by side along the circumference of stator core 10.Above is several
Individual embodiment shows that the arranged evenly of flux arrangement groove 12, number of the arrangement and arrangement position can be relatively any, relative dislocation
Offer effect more preferable.
The invention provides a kind of motor, including stator and the rotor that coordinates with stator, stator is determining of above-described embodiment
Son.In the motor of the present invention, stator is offered flux and is arranged groove, equally reaches to offer flux with rotor and arranges the work that groove is identical
With, and stator teeth is wider, is more prone to fluting.Change flux in prior art and arrange the knot that groove is opened on rotor core
Structure situation, the rotor structure in the present embodiment arranges groove as it is shown on figure 3, need not offer flux on rotor core 20.Owing to offering
On the stator teeth of stator core, the space so making flux arrangement groove to select is bigger, thus the most just reduces magnetic
Bundle arranges the manufacture difficulty of groove, low owing to offering the difficulty of flux arrangement groove, moreover it is possible to improving production efficiency further.
