Below with reference to Fig. 1-Fig. 5, the drive motors 100 for compressor according to the embodiment of the present invention is described.This compressor 1000 comprises bent axle 301.The rotor 2 of drive motors 100 is connected to drive rotation by bent axle 301 with bent axle 301.
According to the drive motors 100 for compressor of the embodiment of the present invention, as depicted in figs. 1 and 2, comprising: stator 1 and rotor 2.Wherein, rotor 2 is set in outside stator 1, and that is, the drive motors 100 for compressor according to the embodiment of the present invention is external rotor electric machine.
See figures.1.and.2, rotor 2 comprises rotation section 21 and multiple magnet 22, and rotation section 21 is configured to tubular construction, and rotation section 21 comprises bent axle connecting wall 211 and sidewall 212, and sidewall 212 is arranged on the upper surface upper or lower surface of bent axle connecting wall 211.
In certain embodiments, as shown in Figure 1, rotation section 21 can be configured to inverted tubular construction, and rotation section 21 comprises roof and sidewall 212, and wherein, sidewall 212 is from the lower surface of roof to downward-extension, and roof forms above-mentioned bent axle connecting wall 211.But the present invention is not limited to this, in other embodiments of the invention, rotation section 21 also can be configured to the tubular construction that top is opened wide, namely towards the opposite with above-mentioned inverted tubular construction opening.In this embodiment, rotation section 21 can comprise diapire and sidewall 212, and sidewall 212 upwards extends from the upper surface of diapire, and diapire forms above-mentioned bent axle connecting wall 211.
In the example shown in Fig. 1 and Fig. 3, bent axle connecting wall 211 comprises the first plate 2111, second plate 2112 and the 3rd plate 2113, first plate 2111 is formed as disc and is provided with axis hole 2114 to be suitable for connecting the bent axle 301 of compressor 1000, second plate 2112 extends from the outer edge of the first plate 2111 towards the direction of sidewall 212,3rd plate 2113 stretches out from the outer edge of the second plate 2112, and the 3rd plate 2113 is connected with sidewall 212.Here, the direction of the central axis PP ' away from the first plate 2111 is outwards referred to.Alternatively, bent axle connecting wall 211 also comprises flange 2115, and flange 2115 arranges the contact area to increase bent axle 301 and bent axle connecting wall 211 along the outer edge of axis hole 2114, thus it is firm that bent axle 301 is connected with rotor 2.
With reference to Fig. 2, multiple magnets 22 are circumferentially distributed in the inner side of sidewall 212, and the gap between adjacent magnet 22 and the internal face of sidewall 212 is by inject with fluid and the conjunction 23 solidify bonded magnet 22 and sidewall 212 afterwards fills.Here, circumference refers to along direction shown in D arrow in Fig. 2.
Particularly, as Figure 1-Figure 5, each magnet 22 extends all along the vertical direction, and each magnet 22 is formed as the tiles structure recessed towards the direction of the central axis PP ' away from sidewall 212, and the outside wall surface of magnet 22 is close on the internal face of sidewall 212.Here, the outside wall surface of magnet 22 refers to the wall of the central axis PP ' away from sidewall 212 of magnet 22, and the internal face of magnet 22 refers to the wall of the central axis PP ' towards sidewall 212 of magnet 22.
More specifically, on the axial direction of sidewall 212 (as indicated by arrow c of figure 1 direction), the length of magnet 22 is connected with the length of sidewall 212, and the length of conjunction 23 is also connected with the length of sidewall 212.By using conjunction 23 to be bonded on rotation section 21 by magnet 22, axial, the circumference of magnet 22 and radial comprehensive spacing can be realized.During in rotor 2 high speed rotating or by External Force Acting, magnet 22 cannot relatively rotate portion 21 and is moved or rotates, thus makes the brow leakage of rotor 2 less, and then improves the utilance of magnet 22.
Because magnet 22 can be completely fixed on sidewall 212 by conjunction 23, make rotor 2 without the need to using the part such as jump ring, engineering glue, magnet Axial Mounting Part of W shape or U-shaped, thus make the building block negligible amounts of rotor 2, reduce the complex structure degree of rotor 2, and then be conducive to the production efficiency improving rotor 2, reduce the hidden danger of quality that parts bring.This version meets the design principle of VAVE.
Meanwhile, because conjunction 23 injects gap with fluid form, make conjunction 23 by the restriction of gap shape, thus the production in enormous quantities of rotor 2 can not be convenient to, and be convenient to the batch production of rotor 2 of different series, model.Simultaneously, because the gap between adjacent magnet 22 and the internal face of sidewall 212 is by inject with fluid and the conjunction 23 of bonded magnet 22 and sidewall 212 fills after solidifying, make sidewall 212, magnet 22 and conjunction 23 can be formed as a close-connected entirety, thus greatly improve the structural strength of rotor 2, the vibration occurred in reduction rotor 2 running and distortion, and then reduce vibration & noise when drive motors 100 runs.
And, because the gap between adjacent magnets 22 and the internal face of sidewall 212 is filled by the conjunction 23 injected with fluid, above-mentioned gap can be filled for combined 23 completely, especially, when gap is irregularly shaped or the machining accuracy of magnet 22 is not high, above-mentioned gap still can be filled by conjunction 23 completely.Thus, when drive motors 100 operates, the additional drag effect of the fluid working substance in the compressor 1000 that rotor 2 is subject to is less, thus reduces the loss of drive motors 100, improves the efficiency of drive motors 100.
In addition, in order to obtain ideal air-gap field distribution, drive motors 100 according to the embodiment of the present invention can be in optimized selection the pole embrace of magnet 22, and design is optimized to the outer shape of magnet 22, with the air-gap field be optimized distribution, thus reduce the air gap flux density harmonic content of drive motors 100.Here, the pole embrace of rotor magnet and the design principle of shape are told about by Patents disclosed in prior art and paper, no longer illustrate here.
It should be noted that, when the pole embrace of magnet 22 and the outer shape (as trimming shape) of magnet 22 change, the gap shape between adjacent magnet 22 and the internal face of sidewall 212 also changes thereupon.Because the conjunction 23 according to the embodiment of the present invention can not, by the restriction of gap shape, make gap can be designed to reduce the shape of air gap flux density harmonic content.Thus, the radial load that drive motors 100 air gap flux density harmonic wave causes in the iron core of stator 1 can greatly reduce, and the vibration & noise situation of drive motors 100 can improve.The cogging torque that causes of the close harmonic wave of this partial air gap magnetic and Cymbidium aloifolium also can greatly reduce simultaneously, and when drive motors 100 runs, the stationarity of torque and rotational speed improves, thus can reduce the vibration & noise of drive motors 100 further.Meanwhile, electromagnetic noise when drive motors 100 runs also can significantly reduce, and by the electromagnetic shielding of the housing of compressor 1000, the impact on around power consumption equipment of the electromagnetic noise of drive motors 100 also can be reduced to very faint level.
According to the drive motors 100 for compressor of the embodiment of the present invention, by using conjunction 23 to be fixed on rotation section 21 by magnet 22, axial, the circumference of magnet 22 and radial comprehensive spacing can be realized.During in rotor 2 high speed rotating or by External Force Acting, magnet 22 cannot relatively rotate portion 21 and is moved or rotates, and the building block negligible amounts of rotor 2, thus is convenient to the production efficiency improving drive motors 100, reduces hidden danger of quality.Simultaneously, due to the gap between adjacent magnets 22 and the internal face of sidewall 212 can combined 23 completely filled, whole rotor 2 be cured as one, rotor 2 intensity improve, be conducive to distortion and the vibration of the rotor 2 that radial electromagnetic force causes when reduction runs, reduce noise when compressor 1000 runs.In addition, the shape restriction of this fixed form to magnet 22 is few, can be convenient to be optimized design to the shape of magnet 22, reduce the magnet consumption of rotor 2 and reduce the air gap flux density harmonic content of drive motors 100, and then the radial load that reduction stator 1 bears, improve the stationarity of torque and rotational speed when drive motors 100 runs, reduce the vibration & noise of drive motors 100, avoid having an impact to around power consumption equipment.
In some embodiments of the invention, conjunction 23 is moulding.Certainly, the present invention is not limited thereto, conjunction 23 also can be Embedding Material part, and such as, conjunction 23 can be epoxy resin part.Thus, conjunction 23 has good mobility before curing, and conjunction 23 is filled evenly, and the bubble of generation is few.
In a preferred embodiment of the invention, the conjunction 23 mixture materials and parts that are polybutene to benzene two hydrochloric acid and glass.Thus, conjunction 23 good fluidity before curing, fluid resistance is little after hardening, resistance to elevated temperatures good for conjunction 23, and conjunction 23 is good with the working medium compatibility in compressor 1000.
Wherein, due to conjunction 23 good fluidity before curing, thus make the conjunction 23 of flow-like can give full play to mobility and the compliance characteristics of fluid, and then make conjunction 23 can fill the gap of arbitrary shape completely.
Due to conjunction 23, fluid resistance is little after hardening, thus surface planarity is higher after hardening to make conjunction 23, thus, can reduce frictional resistance when drive motors 100 operates.In examples more of the present invention, the surface planarity of conjunction 23 is close with the flatness on the surface of the mould adopted, and the surface planarity of conjunction 23 is greater than the surface planarity of magnet 22.
Because conjunction 23 resistance to elevated temperatures is good, thus make conjunction 23 can adapt to the working medium environment of the HTHP of compressor 1000.Simultaneously because conjunction 23 is good with the working medium compatibility in compressor 1000, thus working medium can be avoided the corrosion of conjunction 23, and then improve the useful life of drive motors 100.Wherein, for obtaining and the good conjunction 23 of working medium compatibility in compressor 1000, the composition material of conjunction 23 can carry out proportioning according to the result of the test of different mixed working fluids.
In some embodiments of the invention, due to the exhaust outlet in compressor 1000, fluid passage difference is set, working medium type in compressor 1000 and pressure and other parameters difference, and other structural parameters of being correlated with from flow field is different, makes the flow field in different compressors 1000 different.Therefore, the shape being formed as being conducive to reducing the fluid resistance of rotor 2 when rotating is needed according to the Internal periphery of the rotor 2 of the embodiment of the present invention.
Through Multi simulation running and verification experimental verification, the Internal periphery of the cross section of rotor 2 can be formed as circular, and that is, the inside of rotor 2 can be formed as the chamber turning round the bodily form.Thus, the working medium that can reduce in compressor 1000 flows through resistance during rotor 2, and can adapt to the interior flow field situation of multiple compressor 1000, and then improves the efficiency of compressor 1000.
In some embodiments of the invention, as shown in Figure 2, the end face toward each other of adjacent magnet 22 is irregularly shaped, to increase the contact area between magnet 22 and conjunction 23, thus the adhesive force increased between magnet 22 and conjunction 23, and then add the circumference location of kicker magnet 22 in rotor 2 and axial location, and be conducive to improving air gap magnetic density waveform.
In specific embodiments more of the present invention, in the end face toward each other of adjacent magnet 22 is inclined-plane and/or arcwall face at least partially.Here, the end face toward each other of magnet 22 refers to the face towards another adjacent magnet 22 of magnet 22.Such as, the end face toward each other of magnet 22 can be made up of the plane that multiple angle of inclination is different, and the end face toward each other of magnet 22 can be made up of the arcwall face that multiple degree of crook is different, again such as, in the end face toward each other of magnet 22, a part for plane another part be arcwall face.In the example shown in Fig. 1, Fig. 4 and Fig. 5, the end face toward each other of magnet 22 is made up of the first plane 221 be connected and the second plane 222, has angle between the first plane 221 and the second plane 222.
Certainly, the present invention is also not limited thereto, and such as, the end face toward each other of adjacent magnet 22 can be formed with projection or groove.In addition, when the surface roughness of the end face toward each other of magnet 22 increases, the adhesive force between magnet 22 and conjunction 23 also can increase.
Further, magnet 22 is processed by pressing process.In examples more of the present invention, the compacting tool set of magnet 22 can be arranged to irregular shape, thus magnet 22 be pressed into have erose structure, such as magnet 22 can be pressed out the structure with projection or groove.

Certainly, the present invention is not limited thereto, such as, after magnet 22 has been suppressed, can in the process cutting or grind of magnet 22 after pressing, artificial goes out projection, groove or higher surface roughness.
In some embodiments of the invention, sidewall 212 is magnetic conductive metal part, and such as sidewall 212 can be steel plateelement, and thus, the magnetic conductivity of sidewall 212 is good and mechanical strength is higher.Because sidewall 212 structural strength is comparatively large, sidewall 212 is without the need to adopting the structures such as reinforcement.Alternatively, sidewall 212 is electrical sheet plate.In preferred embodiments more of the present invention, sidewall 212 is 8# or 10# electrical sheet plate.
