Technical field
The present invention relates to a kind of synchronous machine, particularly a kind of compressor of air conditioner permagnetic synchronous motor.
Background technology
The electric air-conditioning compressor electric motor is as the drive motors of air-conditioning, and its operating efficiency and low cruise ability are related to the benefit that social energy conservation reduces discharging.
Concentrate the permagnetic synchronous motor of winding configuration, it is simple to possess manufacturing process, the advantages such as the axial space size is little, but concentrate winding not only to be difficult to obtain good counter potential waveform (form factor generally is lower than 0.9), and cooperate the inscribe permanent magnet rotor can produce larger utmost point leakage reactance, thereby be difficult to obtain good low cruise ability (particularly the low speed position-sensor-free starts ability), the existing rotating speed of winding compressor of air conditioner of concentrating generally can only be in 15% above low speed load running of maximum speed, and be difficult to obtain higher power factor, electromagnetic noise is relatively bigger than normal.
Therefore, need especially a kind of compressor of air conditioner permagnetic synchronous motor, to solve the above-mentioned existing problem that exists.
Summary of the invention
The object of the present invention is to provide a kind of compressor of air conditioner permagnetic synchronous motor, for the deficiencies in the prior art, can keep concentrating under the advantage prerequisite of winding, make motor obtain good counter potential waveform, reduce electromagnetic noise, and effectively reduce utmost point leakage reactance, reduce the low cruise ability of improving motor.
Technical problem solved by the invention can realize by the following technical solutions:
A kind of compressor of air conditioner permagnetic synchronous motor, it comprises rotor and stator, it is characterized in that, described rotor is embedded magnetic steel structure, is provided with the groove identical with motor pole number at described rotor punching, connects by fillet between the described groove; The interior circular arc of the tooth of described stator punching is provided with symmetrical chamfered edge.
In one embodiment of the invention, described groove is V-type or a type groove.
In one embodiment of the invention, the width of described fillet be described rotor punching thickness 1-2 doubly.
In one embodiment of the invention, the arc length of the interior circular arc behind the chamfered edge is 1/8 to 1/4 of stator punching tooth tooth pitch.
In one embodiment of the invention, the notch place rounding of described stator.
In one embodiment of the invention, the cylindrical place of described stator punching is provided with a lead-out wire connector mounting groove.
Further, described lead-out wire connector mounting groove is swallowtail shape.
In one embodiment of the invention, the cylindrical place of described stator punching is provided with the welding procedure groove of some aligning tooth center lines.
Compressor of air conditioner permagnetic synchronous motor of the present invention, compared with prior art, adopt the rotor groove design when concentrating winding, can improve and concentrate winding electric machine waveform sine, reduce leakage reactance, thereby obtain high power factor and efficient, can also reduce cogging torque in addition, low speed load capacity when improving air-conditioning without Position Control realizes purpose of the present invention.
Characteristics of the present invention can be consulted the detailed description of the graphic and following better execution mode of this case and be obtained to be well understood to.
Description of drawings
Fig. 1 is the structural representation that compressor of air conditioner of the present invention is used the permagnetic synchronous motor electromagnetism;
Fig. 2 is the enlarged diagram of stator tooth of the present invention;
Fig. 3 is the enlarged diagram of rotor list magnetic pole of the present invention.
Embodiment
For technological means, creation characteristic that the present invention is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the present invention.
As shown in Figure 1, compressor of air conditioner permagnetic synchronous motor of the present invention, it comprises rotor 100 and stator 200, described rotor 100 is embedded magnetic steel structure, be provided with the groove identical with motor pole number 120 at described rotor punching 110, connect (referring to Fig. 3) by fillet 130 between the described groove 120; The interior circular arc of the tooth of described stator punching 210 is provided with symmetrical chamfered edge 220(referring to Fig. 2).
In the present invention, described groove 120 is V-type or a type groove; The width of described fillet 130 be described rotor punching 110 thickness 1-2 doubly.
In the present invention, the arc length L of the interior circular arc behind the chamfered edge is 1/8 to 1/4 of stator punching 210 tooth tooth pitches; The notch place rounding of described stator 200.
In the present invention, the cylindrical place of described stator punching 210 is provided with a lead-out wire connector mounting groove 230; Described lead-out wire connector mounting groove 230 is swallowtail shape.
The cylindrical place of described stator punching 210 is provided with the welding procedure groove 240 of some aligning tooth center lines.
Make after compressor of air conditioner of the present invention is processed by chamfered edge with the stator punching 210 of permagnetic synchronous motor and generate non-homogeneous air gap between the electric machine rotor, the excitatory of pole pair stator affected by non-homogeneous air gap during rotor, go out to approach sinusoidal wave back-emf at the armature winding internal induction, it is excessively mild between stator tooth that air gap heterogeneous makes the magnetic circuit of permanent magnet generation in addition, make the air gap energy storage of motor circumferencial direction excessive gently, the rotor of even air gap cooperates the cogging torque that can effectively reduce motor relatively, has improved motor low cruise stationarity.
After the position is gone to expect between the magnetic pole of rotor punching 110, form larger groove 120, make the rotor punching 110 of interpolar be in saturation condition after loading onto magnet steel 140, wide region is saturated between the magnetic pole of rotor 100, stator 200 alternate magnetic linkages are difficult to directly form magnetic circuit by rotor surface, so operative constraint the alternate interlinked leakage of stator 200, Effective Raise the power factor of motor.
Lead-out wire connector holddown groove 230 and 240 designs of technique welding groove do not affect the degree of saturation of motor magnetic circuit at the midline position of stator 200 teeth, have relatively saved motor material and bulk.
Compressor of air conditioner permagnetic synchronous motor of the present invention, can keep concentrating under the advantage prerequisite of winding, make motor obtain good counter potential waveform (form factor is higher than 0.95), reduce electromagnetic noise, and effectively reduce utmost point leakage reactance, reduce the low cruise ability of improving motor (can maximum speed 10% with interior low speed load running).
More than show and described basic principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; that describes in above-described embodiment and the specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications; these changes and improvements all fall in the claimed scope of the invention, and the claimed scope of the present invention is defined by appending claims and equivalent thereof.
