Specific implementation mode
The specific implementation mode of the present invention is described in detail below in conjunction with attached drawing.It should be understood that this place is retouched
The specific implementation mode stated is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
In the present invention, in the absence of explanation to the contrary, the noun of locality used such as " upper and lower, left and right " typically refers to
Upper and lower, left and right shown in refer to the attached drawing；" inside and outside " refers to the inside and outside of the profile relative to each component itself.
Shown in Fig. 5, the present invention provides a kind of rotary compressor, including shell and it is set to the shell
Interior permanent magnet synchronous motor, the permanent magnet synchronous motor include stator and rotor.Wherein, the stator of permanent magnet synchronous motor includes stator
Iron core 1 and winding, the stator core 1 have multiple internal tooths 11, stator slot 12, winding cloth are defined between the adjacent internal tooth 11
It sets in the stator slot 12 and is wound in the internal tooth 11；The rotor of the permanent magnet synchronous motor is rotatably mounted in the stator
Inside, and the peripheral surface of the rotor is opposite with the inner end face interval of internal tooth 11 of stator, the rotor include rotor core 2 and
The multiple field structures 3 being circumferentially disposed on the rotor core 2, each field structure 3 include at least one block of magnet 32
And form a magnetic pole, the radial direction of magnet 32 extending direction on the radial section of rotor core 2 and rotor core 2
And angle is respectively provided between tangential direction.
It is understood that the present invention makes extending direction of the magnet 32 on the radial section of rotor core 2 and rotor iron
It is respectively provided with angle between the radial direction and tangential direction of core 2, that is, so that the magnetic structure of rotor is tangentially and radially
Hybrid magnetic structure, this enables rotor core 2 to place magnet 32 to greatest extent to improve the power density of motor, from
And finally so that motor has high efficiency.Specifically, in existing structure, to improve electric efficiency, copper loss is further decreased, it is fixed
12 area of stator slot of son is generally positioned larger, this can cause diameter of stator bore less than normal, limit rotor diameter, thus at this
In kind structure, rotor need to apply above-mentioned hybrid magnetic structure tangentially and radially, to coordinate raising electric efficiency.
According to the above, the rotor diameter of rotor is further set as D2, the axial height of rotor is set as L, presses
The discharge capacity of contracting machine is set as P, and the discharge capacity of rotary compressor of the invention and the size of permanent magnet synchronous motor meet relational expression：
0.085≤P/(D2 2*L)≤0.11.Specifically, the present invention passes through to above-mentioned permanent magnet synchronous motor and with its rotary pressure
Contracting machine is studied, and the COP (performance of compressor machine) for having obtained compressor as shown in Figure 4 changes song with P/ (D22*L)
Line.According to the curve it is found that as 0.085≤P/ (D2 2* L)≤0.11 when, compressor performance highest and tend to be steady；Work as P/
(D2 2* L) ＞ 0.11 when, since the rotor moment of inertia of motor is smaller, cause compressor stress unstable, motor efficiency caused to play
Poor while compressor efficiency reduces；As P/ (D2 2* L) ＜ 0.085 when, then rotor rotary inertia is excessive, and motor is caused to damage
Consume it is larger, so as to cause compressor efficiency reduce.The invention enables 0.085≤P/ (D2 2* L)≤0.11, in the range, rotation
The performance of formula compressor can be up to standard, that is, the value of the rotor inertia of permanent magnet synchronous motor is more appropriate.
Through the above technical solutions, size and rotary compression of the present invention by the efficient permanent magnet synchronous motor of restriction
Relationship between the discharge capacity P of machine, to be limited in the rotary inertia of the rotor of the permanent magnet synchronous motor in reasonable range.This
The permanent magnet synchronous motor of invention improves the rotary inertia of rotor, and then improve rotation while ensureing that electric efficiency improves
The efficiency of rotary compressor and the noise vibration deterioration for effectively preventing rotary compressor.
As a kind of preferred structure of the present invention, the rotor diameter D of rotor2It can expire between the axial height L of rotor
Sufficient relational expression：L/D2≤0.9.The present invention has been obtained by studying rotary compressor and permanent magnet synchronous motor such as Fig. 5
Shown in compressor noise value (dB) with L/D2Change curve, according to the curve it is found that working as L/D2Compressor drum when≤0.9
Caused tangential vibrations are smaller, and caused noise is smaller, works as L/D2The noise of compressor drastically deteriorates when ＞ 0.9.The present invention makes
Obtain L/D2≤ 0.9, this permanent magnet synchronous motor has smaller L/D2, so " short and stout " shape is substantially presented in rotor shapes, can effectively subtract
The tangential vibrations of small rotary compressor are to reduce the noise of rotary compressor, to improve the entirety of rotary compressor
Performance.
Stator outer diameter is set as D1, the diameter of stator bore of stator is D12, the two further meets relational expression：D12/D1≥0.57。
It is understood that when the ratio of diameter of stator bore D12 and stator outer diameter D1 is less than 0.57, diameter of stator bore D12 is relatively too small, this
Rotor diameter D2 will be significantly limited, so that the rotary inertia of rotor is less than normal.And work as diameter of stator bore D12 and stator outer diameter
When the ratio of D1 is more than 0.57, diameter of stator bore D12 is relatively large, and then enables to rotor diameter D2 biggers.Since permanent magnetism is same
It is relatively large to walk rotor outer diameter D 2, so rotary inertia being capable of bigger so that rotor has stronger Ability of Resisting Disturbance, right
In the nonlinear load of single cylinder rotary compressor, it can be effectively improved the problem of low-frequency compression machine stress shakiness, and improve pressure
Contracting machine noise.
Whole magnet 32 in each field structure 3 preferably form opening outwardly on the radial section of rotor core 2
V-arrangement or W-shaped.Specifically, field structure 3 has two blocks of magnet 32, radial section of the two blocks of magnet 32 in rotor core 2
On be formed as the V-arrangement outwardly of being open；There are field structure 3 four blocks of magnet 32, four blocks of magnet 32 to be cut in the radial direction of rotor core 2
Be formed as outwardly W-shaped of being open on face, of course, whole magnet 32 in each field structure 3 are cut in the radial direction of rotor core 2
The similar structures such as the U-shaped of opening outwardly can also be formed on face.This hybrid magnetic structure manufacture it is relatively simple, can
The complexity of processing is reduced to a certain extent, while V-arrangement and W-shaped hybrid magnetic structure mechanical strength are more preferable so that electricity
The output power bigger of machine.
Each field structure 3 can further include the magnetic pole slot 31 being axially arranged on rotor core 2, the magnetic pole slot
31 on the radial section of the rotor core 2 in opening V-arrangement or W-shaped outwardly, whole magnet in each field structure 3
32 are set in the magnetic pole slot 31.This set makes magnet 32 be convenient for forming opening court on the radial section of rotor core 2
Outer V-arrangement or W-shaped, meanwhile, this built-in field structure 3 is so that magnet 32 is more firm, so that permanent magnet synchronous electric
The stability higher of machine.Particularly, magnetic pole slot 31 can further run through rotor core 2 and be arranged, this so that 32 volume of magnet can
With bigger, rotor quality more balances.
Permanent magnet synchronous motor is preferably using concentration volume electric machine structure, that is, sets the number of phases of permanent magnet synchronous motor as m, determines
The number of pilot trench 12 is Q, and the number of magnetic pole is A, then Q/ (2mA)=0.5.The permanent magnet synchronous motor of this structure can save electricity
The copper dosage in generator terminal portion, to further increase electric efficiency.The magnet of the present invention may further be made of rare earth material, and should
