Wherein, to coordinate coiling, stator slot 2 is formed as the substantially rectangular groove for radially extending, the bond length of stator slot 2
It is D.Especially, the radial inner end of stator slot 2 is also formed with connected entrance 3, the insertion vertically of connected entrance 3 and radially connects center
Through hole 4, circumferential openings width of the connected entrance 3 at the inner peripheral of stator punching 1 is a, and is met：A/D=0.1~0.5.
Described in brought forward, increase for the leakage field of stator tooth 5 that the stator slot for changing the closed slot structure shown in Fig. 3 is brought,
And then influence the problem of the conduction of armature field and main flux, the present invention especially on the basis of closed slot structure, to devise
Connected entrance 3, i.e. stator slot 2 use hatch frame.The radially inner side of stator slot 2 forms opening, can no doubt improve cogging torque, i.e.,
Noise increases, but inventor draws on the basis of multi-party trial, summary and repetition test, measuring and calculating, is limited in A/F
In the case of minizone, its raising DeGrain to cogging torque but can significantly reduce the leakage field of stator tooth 5, make
Electric efficiency is substantially improved.
Specifically, the circumferential openings width when connected entrance 3 at the inner peripheral of stator punching 1 is a, and is met：A/D=
0.1~0.5, especially during a/D=0.2~0.5, calculated by electromagnetism, the setting of connected entrance 3 (about 2% width only a little
Degree) improve cogging torque, i.e. noise elevating effect is very little, but can largely reduce the leakage field of stator tooth 5, finally
Significantly (0.6%) improves electric efficiency.
Referring to Fig. 4, the circumferential openings width everywhere of the preferably rectangular connected entrance of connected entrance therein 3, i.e. connected entrance 3 is equal
It is identical.Preferably, OO ', i.e. connected entrance 3 are arranged on the footpath of stator slot 2 to the midline with common footpath for connected entrance 3 and stator slot 2
The middle part of inboard end so that the width of the stator tooth boots 51 of each stator tooth 5 is identical.
Referring to Fig. 5, in the connected entrance 3 of another structure type, connected entrance 3 is formed as radially outer open shape, i.e.,
Circumferential openings width a of the connected entrance 3 at the inner peripheral of stator punching 1 is the minimal openings width of connected entrance 3, and connected entrance 3 exists

In Fig. 4, Fig. 5, the bond length D of stator slot 2 is both preferably 1.6mm~4.2mm.According to existing compressor of air conditioner
Common power scope (0.5 watt~5000 watts), the outside diameter d 1 of the stator punching 1 of its motor is normally controlled in 80mm~160mm
In the range of.For multiple-grooved rectangular groove structure motor of the invention, it usually needs ensure that stator slot 2 has enough slot cross-section faces
Product can be put into the stator winding (such as enamel-cover copper rectangular winding wire) of at least 4 or more, thus generally by the internal diameter of stator punching
D2 is arranged on the internal diameter d2 scope controls of 0.5~0.6, i.e. stator punching 1 in 40mm~96mm with the ratio of outside diameter d 1.Additionally,
Compressor 300 generally runs under the Power Supplies Condition of DC bus-bar voltage 300V~500V, and motor certainly will also be set properly
Anti-electromotive so that motor running is under high efficiency operating mode.To obtain suitable Anti-electromotive, the number of stator slot 2
Amount should be preferably controlled within the range of 36~72.
Thus, according to above parameter and the reasonable layout of the magnetic flux density for considering stator tooth 5, the short side of rectangular stator groove 2
The preferred length scope of length D is 0.9mm~4.2mm.But then, multiple-grooved rectangular groove structure motor typically uses multistage
Enamel-cover copper rectangular winding wire is connected to become armature coil 30 by limited number of time, therefore the present invention also should be in accordance with GB GB/T 7095.1-
2008 pairs of regulations of enamel-cover copper rectangular winding wire.In the regulation, the minimum conductor bond length of enamel-cover copper rectangular winding wire is
0.8mm, nominal film thickness 0.085mm.And also need to insert 0.125mm to meet motor proof voltage requirement, in stator slot
The PET material of~0.25mm thickness as insulating materials 20, referring to Fig. 1.The gap that above material passes through about 0.05mm-0.1mm
Cooperation is inserted into stator slot 2.Dimensions above be superimposed limit rectangular stator groove 2 short side width need to more than 1.6mm, therefore
It is preferred that the scope for drawing the bond length D of rectangular stator groove 2 is above-mentioned 1.6mm~4.2mm.
To sum up, electricity can be taken into account using the compressor 300 and its motor of stator core according to the first aspect of the invention
The relatively low, low noise less with stator tooth 5 leakage field of machine cogging torque, the plurality of advantages of high workload efficiency.
According to the second aspect of the invention, another stator core is additionally provided, as shown in Fig. 3, Fig. 6, the stator core
The 10 same multi-disc stator punchings 1 for including laminating, the thickness of monolithic stator punching 1 is usually more than 0.5mm, and stator punching 1 is excellent
Elect circular ring plate as, be provided with the anchor ring of stator punching 1 axially through and circumferentially spaced arrangement multiple stator slots 2.Its
In, stator slot 2 is the rectangular channel for radially extending, and the corner of rectangular channel is uniquely formed as rounded corner 21, that is, has carried out rounding
Angle is processed.
It can be seen that, for the minimum widith for changing stator tooth 5 (as shown in Figures 4 to 6) trapezoidal in the prior art is too small, cause
The close excessively saturation of teeth portion magnetic, and then iron loss is greatly improved, influence the problem of electric efficiency, the present invention pointedly to devise rectangle
The shape of stator slot 2, on the basis of substantially rectangular elementary contour is not changed, the rounded corner 21 of optimization design corner can increase

Meter can coordinate the technique fillet of winding conductor in rounded corner 21 and groove so that maximally utilize groove area so that motor have compared with
Stator copper factor high, so that final lifting motor efficiency.
In theory, stator winding has been passed around in stator slot 2, now the radius of corner of the semiconductor process fillet of stator winding should
Less than the radius of corner of the rounded corner 21 of stator slot 2, so that stator winding can be close on the curved wall of rounded corner 21, carry
Stator copper factor high.
Specifically, when the geomery of stator slot 2 is closed with the cross sectional shape matching size of enamel-cover copper rectangular winding wire, can be most
Bigization utilizes groove area, it is ensured that copper factor higher, and most important of which key element is the cooperation of semiconductor process fillet size.
The conductor fillet of enamel-cover copper rectangular winding wire is specified according to GB GB/T 7095.1-2008：Conductor bond length model
It is trapped among between 0.8~1.0mm, conductor radius of corner is the 1/2 of conductor short side；Conductor bond length scope 1.0~
Between 1.60mm, conductor radius of corner is 0.5mm；Conductor bond length scope between 1.6~2.24mm, conductor fillet
Radius is 0.65mm；Between 2.24~3.4mm, radius of corner is 0.8mm to conductor bond length scope.
Preferably rectangular stator groove 2 is drawn after conductor radius of corner superposition paint film, the size of insulating materials 20, process gap
Fillet size, and the bond length D of rectangular stator groove 2 defines conductor bond length, therefore preferably show that rectangle is determined
The ratio of the bond length D and radius of corner R of pilot trench 2 meets relation：The radius of corner of D/R=2~4, i.e. rounded corner 21 is maximum
No more than D/2, minimum should be greater than D/4, more than semiconductor process fillet.
As it was previously stated, in the compressor electric motor of application to conventional air-conditioning, the bond length D of stator slot 2 is preferably 1.6mm
~4.2mm, it is no longer repeated herein.In the case, accordingly, the radius of corner R of the rounded corner 21 of stator slot 2 is preferably
0.5mm~2mm.
Wherein, rectangular stator groove 2 is provided preferably with four rounded corners 21, and each radius of corner all same, to improve stator
Copper factor.The sectional area of stator slot 2 is likewise provided as can parallel through the stator winding of at least four.
It can be seen that, two neighboring stator slot 2 limits stator tooth 5, and the geomery of stator slot 2 limits the chi of stator tooth 5
It is very little, therefore the fillet of stator slot 2 rationally sets size, can ensure the constant situation of the copper factor of motor, as wide as possible
Increase the width of stator tooth 5, reduce tooth magnetic close.
Further, what stator core according to the second aspect of the invention can also be shown in integrated Fig. 2 is of the invention
The design of the stator core of first aspect, the i.e. radial inner end of stator slot 2 is formed with connected entrance 3, the insertion vertically of connected entrance 3 and
Radially connect central through hole 4.When circumferential openings width of the connected entrance 3 at the inner peripheral of stator punching 1 is a, stator slot 2
When bond length is D, preferably meet：A/D=0.1~0.5, more preferably a/D=0.2~0.5.The advantage that it brings is for example preceding
It is described, also no longer carefully state one by one herein.
To sum up, stator core according to the second aspect of the invention, can be with simultaneous when compressor 300 and its motor is applied to
