This compressing mechanism 22 comprises the first and second mechanical components, is illustrated as and cooperatively interacts thus the form of the scroll element 54,56 of compression working fluid.In the embodiment shown, the first scroll element 54 is fixed rotationally relative to the second scroll element 56.In related domain, the first scroll element 54 also can axially movably be fixed relative to the second scroll element 56 in a well-known manner in inner chamber 28.Second scroll element 56 is operably connected with this driving mechanism 24 so that by crank pin 58 with drive lining 60 to be in transmission connection on the axle 52 of electric motor assembly 26, make the second scroll element 56 can as described below relative to the first scroll element 54 along rail moving.
Non-Orbiting scroll element 54 and Orbiting scroll element 56 are located in the mode be engaged with each other, suitable conventional coupled modes generally allow the eccentric orbit between them to move (along a circular path), but forbid the relative rotary motion between them.The top 32 of dividing plate 62 generally this housing 30 contiguous arranges and is used for inner chamber 28 to be separated into the discharge side 64 being positioned at upper end and the suction chamber 66 being positioned at lower end, positive copy exercising ordinary skill according to present disclosure can easily understand that such.
As those of ordinary skill in the art's easy understand, when the first non-Orbiting scroll element 54 and the second Orbiting scroll element 56 relative to each other move axially to the primary importance corresponding to load condition, this compressing mechanism 22 is configured to compression working fluid during the electric motor assembly 26 of driving mechanism 24 rotates and runs with complete (100%) capacity.Or, when the first non-Orbiting scroll element 54 and the second Orbiting scroll element 56 relative to each other move axially to the second place corresponding to unloaded state, this compressing mechanism 22 is configured to not compression working fluid running with zero (0%) capacity, even also like this during the electric motor assembly 26 of driving mechanism 24 continues to rotate.By this way, the capacity of this digital scroll compressor assembly 20 can change quickly and efficiently and not necessarily change the rotating speed of the electric motor assembly 26 of this driving mechanism 24.
Layout to axial between first non-Orbiting scroll element 54 and the second Orbiting scroll element 56 such as, is moved by operating by control gear (not shown, solenoid valve), and this is well known in the art.Therefore, by suitably changing load condition time and unloaded state time within arbitrary given cycle, this digital scroll compressor assembly 20 can be to fixed system transmit needed for arbitrary capacity, positive copy exercising ordinary skill according to present disclosure can easily understand that such.
At complete (100%) capacity run duration, when the second Orbiting scroll element 56 Orbiting scroll element non-relative to first 54 orbiting, working fluid to be compressed is inhaled into by import 44 in the suction chamber 66 of the inner chamber 28 of this digital compression thermomechanical components 20.Leave suction chamber 66, working fluid enters by scroll element 54, the compression chamber 68 that the volume that a part of 56 limits jointly reduces.The intermeshing scroll wrap (intermeshingscrollwrap) of scroll element 54,56 defines the mobile depression (movingpockets) of working fluid in compression chamber 68 inside, due to the orbiting of the second Orbiting scroll element 56, these sizes moving depression reduce gradually when it radially moves, and therefore compress the working fluid entered by import 44.Then the working fluid through overcompression is discharged into discharge side 64 and discharges this digital compression thermomechanical components 20 through outlet 46.
At zero (0%) capacity run duration, even if the orbiting of the second Orbiting scroll element 56 Orbiting scroll element 54 non-relative to first, scroll element 54,56 also move axially to unloaded state away from each other, so there is no the suction formed by compression chamber 68, also not by a large amount of flowings of the working fluid of this digital compression thermomechanical components 20.Because this digital compression thermomechanical components 20 can be run by zero (0%) capacity when the second Orbiting scroll element 56 Orbiting scroll element 54 non-relative to first moves, this compressing mechanism 22 can by driving mechanism 24 effectively and drive expeditiously, this driving mechanism comprises the across-the-line starting brushless permanent magnet electromotor assembly 26 being configured to single speed motor, as detailed description hereinafter.

As some routine in related domain, each independent stator laminate patch 80 comprises the steel body being essentially annular, therefore form the stator laminate patch 80 center axial bore 82 that formation one is overall jointly that multiple axis of stator core body 76 are stacking, be used for holding rotor assembly 70.As those of ordinary skill in the art's easy understand, air gap 84 is radial between the stator core body 76 and rotor assembly 70 of stator module 74 to be extended, and rotor assembly 70 can be rotated at stator module 74 internal freedom.
The stator laminate patch 80 that multiple axis of formation stator core body 76 are stacking is also formed multiple axially across the groove 86 being roughly arc wherein jointly, and each described groove 86 is communicated with air gap 84.As those of ordinary skill in the art's easy understand, the wire of conduction forms winding 78, and this winding is through groove 86 and be contained in wherein.Note, in the illustrated embodiment, the stator core body 76 of stator module 74 comprises 24 grooves 86, but optionally arranges the groove of varying number when not departing from the present invention's instruction.
The electric motor assembly 26 of shown embodiment is configured to three phase motor.Temporarily turn to now three phase motor and the consideration of the operation of winding details that wherein uses, those of ordinary skill in the art's easy understand three phase motor is compacter often and to compare cost less with same electric pressure and the single phase motor of loading factor.In addition, often to demonstrate the same power single-phase motor that therefore less vibration use than accordingly, under the same conditions more durable for many three phase motors.But principle of the present invention is not restricted to three phase motor, single phase motor (not shown) can also be applied to equally.In more detail, the electric motor assembly 26 of illustrated embodiment is configured to single speed motor.
The same with the convention in related domain in a way, winding 78 comprise for three power supplys mutually in each phase winding, this is those of ordinary skill in the art's easy understand.For simplicity, be briefly pointed out that the winding construction of three phase motor is well known in the art, need not describe in detail at this.With reference to figure 3, in illustrated embodiment of the present invention, stator module 74 comprises power connector 88, and this power connector comprises the wire that three are connected to power supply (not shown), one in each wire correspond to three power supplys mutually in each.As can be readily understood, temporal references Fig. 2, stator power connector 88 is electrically connected with compressor power connector 42 as above.
It is envisaged that the winding 78 of across-the-line starting brushless permanent magnet electromotor assembly 26 can comprise copper (being also generally usual), or aluminium (as illustrated) can be comprised, as next further described.Although notice that the winding 78 comprising aluminium can also comprise other materials (such as, the aluminium of aluminum alloy or deposition copper), the winding 78 of illustrated embodiment is made up of aluminum steel in fact.Next other details and unpredictalbe advantage of this atypia winding material in the brushless permanent magnet electromotor assembly 26 of across-the-line starting will describe in further detail.
Next the detailed construction of rotor assembly 70 is turned to, and concrete reference drawing 4, rotor assembly 70 roughly comprises rotor core body 90, and this rotor core body comprises the stacking rotor laminate patch 92 of axis that multiple and multiple aluminium bar 94 is integrally formed (such as passing through die casting).Rod 94 axially extends along multiple rotor laminate patch 92 and comprises the aluminium ring (not shown) arranged along the corresponding axial edge of device.As those of ordinary skill in the art's easy understand, the specified structure of this rod 94 directly affects the start-up function of electric motor assembly 26.Very clear, the routine configuration in the ordinary course of things of this rod, includes but not limited to, around the helically twisted rod of rotor core body 90 or the rod not having distortion at all, can estimate and obviously fall into scope of the present invention.
Continue with reference to figure 4, each independent rotor laminate patch 92 comprises the steel body being essentially annular, and the stacking rotor laminate patch 92 of the multiple axis making to form this rotor core body 90 forms radial outer periphery part 96 and jointly axially across the axis hole 98 axially aligned to hold axle 52.In addition, formed the stacking rotor laminate patch 92 of multiple axis of this rotor core body 90 further common formed multiple axially across the overall groove 100 for arc, each groove 100 at least contiguous (if not connection) this radial outer periphery part 96 is arranged.As is well understood in the art, aluminium bar 94 is formed through groove 100, thus the radial outer periphery part 96 of this rotor core body 90 at least contiguous is arranged, thus jointly limit it at least partially (if the rotor subject of rod is exposed in common formation).Note that in the illustrated embodiment in which, each rotor laminate patch 92 comprises 34 grooves 100, but can arrange the groove of varying number similarly when not departing from the present invention's instruction.
Rotor assembly 70 comprises multiple permanent magnet 102 be arranged on rotor core body 90 further, and this permanent magnet 102 axially extends along rotor core body 90 on the whole.In the illustrated embodiment, permanent magnet 102 is placed in that jointly limit in multiple rotor laminate patches 92 of rotor core body 90, elongated substantially opening 104.At least one rotor laminate patch 92 is set to contact with each in multiple permanent magnet 102 thus permanent magnet 102 is remained on the appropriate location in rotor core body 90.
In more detail, still pay close attention to Fig. 4, each in multiple permanent magnet 102 is parallel to axle 72 substantially and arranges.In addition, the radial outer periphery part 96 of each this rotor core body 90 contiguous substantially in multiple permanent magnet 102 is arranged.Although as those of ordinary skill in the art's easy understand, the permanent magnet 102 be arranged on rotor core body 90 may have varying number and structure (not shown), has been described in the drawings a particularly advantageous structure.
In schematic structure, rotor assembly 70 comprises four permanent magnets 102, and each permanent magnet 102 has size equal in fact.As Fig. 4 sectional view seen in, four permanent magnets 102 become two to setting on the cross section of rotor core body 90, and every a pair permanent magnet 102 is symmetrical to permanent magnet 102 relative to axis 72 and another on the whole.In the illustrated embodiment, each permanent magnet 102 of the brushless permanent magnet electromotor assembly 26 of across-the-line starting comprises neodymium.
Temporary transient steer motor efficiency now, those of ordinary skill in the art are it is easily understood that become the important financial burden of end user in the energy cost that the length of life of motor is relevant with electric motor operated.Therefore, total the improvement of motor efficiency, even if this improvement is only relatively little percentage also can produce remarkable energy saving cost in motor length of life.Therefore, in motor designs or structure, causing the inventive improvements of efficiency gains to have significant competitive advantage, is not only to motor itself, is also not always the case to comprising the equipment (such as digital compression thermomechanical components 20) improving motor.
Relative to above-mentioned efficiency background, should be noted that in certain embodiments of the present invention, compared with existing across-the-line starting brushless permanent magnet electromotor, the rotor assembly 70 (comprising multiple permanent magnet 102) in across-the-line starting brushless permanent magnet electromotor assembly 26 with the unconventional combination of stator module 74 (comprising the winding 78 that aluminium is formed), motor performance is significantly improved greatly reducing to obtain in incremental cost.This performance raising is those of ordinary skill in the art is unexpected.
More particularly, compared with winding made of copper, the winding be made up of aluminium (this is the material more cheap than the copper forming winding) puts the relatively significantly loss of rate aspect from more meeting total motor historical point view.Such as, as can be seen from before test, in the existing embodiment of induction motor, copper winding causes total motor efficiency aspect relatively significantly loss (efficiency drops to about 89% from about 91%) of about 2% to the change of aluminum winding.
As those of ordinary skill in the art's easy understand, the conformity between efficient and high cost makes conventional across-the-line starting brushless permanent magnet electromotor become the high-quality motor that a kind of hope is designed with peak performance.It is well known that relative to other typical induction motoies, permanent magnet significantly increases cost of material.Therefore, the conventional design of existing across-the-line starting brushless permanent magnet electromotor is unanimously instructed, and the high-grade permanent magnet of high cost of rotor is corresponding supporting to the high cost high grade copper winding of stator.
But in some embodiment's situation of the present invention, unexpectedly determine, the across-the-line starting brushless permanent magnet electromotor assembly 26 with aluminum (being usually not used in the material of high-performance motor winding) winding 78 only shows trickle performance difference compared with the existing across-the-line starting brushless permanent magnet electromotor with copper winding.Such as, observe, compared with that show in testing with above-mentioned induction motor, relatively consistent decrease in efficiency, counterintuitively in the present invention be combined in total motor efficiency aspect and produce relatively little loss, be only equivalent to the loss of observe in induction motor as above test about 1/2nd.More particularly, to put in rate at total motor with the across-the-line starting brushless permanent magnet electromotor assembly 26 of aluminum winding 78 and only have the loss of about 1% (efficiency drops to about 94% from about 95%).
In addition, the cost of material of quite most permanent magnet 102 can be made up as the aluminium material of the winding 78 of some embodiment of across-the-line starting brushless permanent magnet electromotor assembly 26.In one embodiment, as mentioned above, across-the-line starting brushless permanent magnet electromotor assembly 26 with aluminum winding 78 manufactures with the incremental cost lower than the embodiment with copper winding, and the electric motor assembly 26 of this low cost has the motor efficiency of about 94%.
But it is once more emphasized that, and not all across-the-line starting brushless permanent magnet electromotor assembly 26 all comprises aluminum winding 78.But some embodiment particularly pointing out across-the-line starting brushless permanent magnet electromotor 26 comprises copper winding 78 (not shown).Comprise copper winding, this embodiment of across-the-line starting brushless permanent magnet electromotor assembly 26 can bring about 95% efficiency, this can bring the even higher overall system performance of digital compression thermomechanical components 20.
As above, preferred form of the present invention only as example, can not separate group's scope of the present invention with restrictive, sense.When not departing from essence of the present invention, those skilled in the art are easy to obviously improve exemplary embodiment, as described above.
Therefore inventor's statement, but rely on similar theory scope fair for appropriateness of the present invention to be determined and be expressed as described in following claims, belong to the arbitrary equipment not departing from essence and exceed character express scope of the present invention.
