At first, form of implementation 1 of the present invention is described.
Fig. 1 is the figure that the motor compressor of the invention process form 1 is shown, and axial section configuration is shown, and Fig. 2 is the figure that the permanent magnet rotary electric machine of the invention process form 1 is shown, and the Q-Q that Fig. 1 is shown is section configuration radially.The axial section configuration of the permanent magnet rotary electric machine as electronic key element shown in Figure 1 is the P-O-P sectional view of permanent magnet rotary electric machine shown in Figure 2.Fig. 3 is the perspective view that is shown in the permanent magnet rotary electric machine of Fig. 2.Fig. 4 is the figure that the electromagnetic steel plate contact condition in the framework is shown.
In Fig. 1, the outward appearance of motor compressor 1 is formed by housing.Housing is made of the loam cake 3 of framework 2 cylindraceous, upper end side, the lower cover 4 of lower end side.Framework 2 is the container of sealing.
In this framework 2, accommodate electronic key element 5 and the compression key element 6 that is called as scroll compressor as permanent magnet rotary electric machine.
The pressing chamber 14 that forms by fixed scroll member 7 and rotation scroll element 10 (14a, 14b ...) in the pressing chamber that is positioned at outside diameter along with rotatablely moving towards the central mobile of two scroll elements 7,10, volume dwindles gradually.The center that pressing chamber 14a, 14b reach two scroll elements 7,10 is nearby the time, from exhaust port 16 discharges of pressurized gas from being communicated with pressing chamber 14 of the suction pipe 15 in two pressing chambers 14.
The pressurized gas of discharging arrives in the framework 2 of fixed component 17 bottoms by the gas channel (not shown) of being located at fixed scroll member 7 and fixed component 17, is discharged to outside the motor compressor 1 from the discharge tube 18 of being located at framework 2 sidewalls.
The electronic key element 5 that is made of permanent magnet rotary electric machine that constitutes motor compressor 1 is turned round by the rotating speed that is suitable for compressed action by frequency conversion (pressures) device (イ Application バ one ) the (not shown) control that is provided with separately.Here, the electronic key element 5 that is made of permanent magnet rotary electric machine is by stator 19 and rotor 20 (though not shown, counterweight block is installed at the two ends of rotor 20).The upside of being located at the crank up axle 13 of rotor 20 becomes crankshaft.Form oilhole 21 in the inside of crank up axle 13, the lubricant oil that will be in the oil storage portion 22 of framework 2 bottoms by the revolution of crank up axle 13 supplies to the following side bearing portion 24 of last side bearing portion 23, the ball bearing mode of sliding bearing formula by oilhole 21.In addition, label 25 is a tenminal block, and the electric power of self frequency-changing's device supplies to electronic key element 5 in the future.Label 26 is a base.
The electronic key element 5 that is made of Fig. 1, permanent magnet rotating electric machine shown in Figure 2 is made of stator 19 and rotor 20, and stator 19 comprises the stator iron core 29 that is made of tooth 27 and iron core back 28 and surround the staor winding 31 (U phase winding 31a, the V phase winding 31b, the W phase winding 31c that comprise three phase windings) of the concentrated winding that twines on tooth 27 ground in the groove 30 of 27 in tooth.The recess 32 of semi-circular shape is set in the periphery of the stator iron core 29 of tooth 27 parts of living in.
Here, be 4 utmost points, 6 grooves as the electronic key element 5 of permanent magnet rotary electric machine, so, when slot pitch is represented by electric angle 120 degree.Rotor 20 nearby forms permanent magnet patchhole 34 at the outer surface of rotor iron core 33, and this rotor iron core 33 forms the revolution axis hole 39 that inserts the turning axle (not shown), the fixing permanent magnet of being made by the neodymium of terres rares 35 in permanent magnet patchhole 34.Label 36 is the periphery of stator iron core 29, becomes with turning axle to be concentric circles.
In Fig. 1, Fig. 2, Fig. 3, label 37 is the most peripheral of stator iron core, sets the diameter bigger slightly than the periphery 36 of stator iron core.That is, the external diameter of periphery 36 parts of stator iron core is little, and most peripheral 37 parts of stator iron core form bigger external diameter.
As make the periphery 36 of stator iron core too small, the magnetic property of permanent magnet rotary electric machine is worsened, so the deviation setting of 36 and 37 diameter is in 0.5mm.
The outside in the periphery 36 of stator iron core 29 forms 2 projectioies 38 (contacting part of convex) that comprise 38a and 38b, and the outer circumferential face of projection 38 (contacting parts of convex) becomes with the most peripheral 37 same diameter ground of stator iron core 29 to be set.Here, (peripheries that recess is 32) are provided with 2 projectioies 38 (contacting part of convex) on the periphery of each groove 30, but also can be 1, or are any number.The height of projection 38 (contacting parts of convex) is about 0.3mm, and width is about 0.5mm.This projection 38 (contacting part of convex) makes electromagnetic steel plate conjointly arrange at the stack direction that overlaps.Stator iron core lamination ground forms the electromagnetic steel plate of 0.35mm or 0.5mm.
Because it is cylindric that framework 2 forms by the tabular steel plate of warpage, so the drum diameter dimensional accuracy in interior week is looser, general size is changed to ± 100 μ m.As a result, hot charging is coupled to contacting wherein with the periphery of stator iron core 29 in interior week that the stator iron core 29 of the stator 19 in the framework 2 can not regulation framework 2.The radially section configuration of the P-O-P section of the permanent magnet rotary electric machine of Fig. 2 shown in Figure 1, the part that contacts with the inner peripheral surface of framework 2 is the projection 38 (contacting part of convex) of the most peripheral 37 of stator iron core 29, and the periphery 36 (external diameter is little) of stator iron core does not contact with the inner peripheral surface of framework 2.For this reason, arbitrary electromagnetic steel plate of formation stator iron core 29 all is contacted with the interior week of framework 2.But the interior weekly form area of the long-pending relative framework 2 of the outer surface of projection 38 (contacting parts of convex) only contacts 1%.
In Fig. 4, (usually thickness is that interior all sides of 2.5mm～3.5mm) support electromagnetic steel plate by 2 projectioies 38 (contacting part of convex) that are formed at the electromagnetic steel plate periphery with hot charging to the framework 2 of cylinder.Formation space portion 40 between the periphery 36 of framework 2 and stator iron core, most peripheral 37 like that shown in peripheral shape 41 parts of the outer circumferential side of electromagnetic steel plate that the supporting of this hot charging only is shown.
In addition, the periphery area of contact of projection 38 (contacting parts of convex) is set at framework 2 inner peripheral surface long-pending (axial length that comprises stator iron core) 1%.As a result, the vibration of stator iron core 29 is difficult for being delivered to framework 2.
Fig. 5 is with illustrating the noise that above-mentioned motor compressor 1 is measured.The cooling and heating ability of this motor compressor 1 is nominal 2.2kW～2.8kW, encloses R410A as refrigerant and makes its work.Measure microphone in the position of the axial central part of the electronic key element 5 that constitutes by permanent magnet rotary electric machine, leave 1m and measure (rice).
The transverse axis of Fig. 5 is a frequency content, and the longitudinal axis is a noise, and the motor compressor in the past and the determination data of motor compressor of the present invention are shown in the lump.The motor compressor in past does not have the projection 38 (contacting part of convex) of the periphery of stator iron core 29, and the periphery 36 of stator iron core 33 is along stack direction (axially) even contact.
As shown in Figure 5, for 200Hz, 400Hz, 8kHz, and 10kHz composition, the noise ratio of motor compressor 1 of the present invention increases in the past slightly, but the noise ratio of the motor compressor of the present invention 1 of frequency content in addition reduces in the past significantly.Fig. 6 illustrates total (OA) value of noise.As shown in Figure 6, the noise ratio of motor compressor 1 of the present invention has reduced 10.4dB in the past significantly.
The stack direction (axially) that this noise is reduced in stator iron core 29 is identical, makes with the area of contact of circumferential framework inner peripheral surface to contact by 1% of all gross areas in the framework (axial vector of stator iron core 29), and the vibration of stator iron core 29 is difficult for being delivered to framework 2.About the projection 38 (contacting part of convex) of this contacting part though area of contact be original 57.5%～28.75%, noise does not change yet, so, be preferably the less area of contact of a few percent (number %).About this contacting part, describe from the assembling aspect of stator iron core 29.
Though lamination is made stator iron core 29 with the electromagnetic steel plate of punch press stamping-out, this is stacked in and is called along carrying out in the palletizing die that send mould (ホ ロ one ダ イ).Consistent with the internal diameter of the external diameter of the corresponding electromagnetic steel plate of the most peripheral 37 (external diameter is big) of stator iron core 29 and palletizing die, so, even carry out lamination in the mould, electromagnetic steel plate also not towards radially offset position, arrives lamination under the state of stack direction (axially) in unification well in mould.
Therefore, can provide noise little and available being called along the stator iron core that send the palletizing die lamination of mould.
In addition, the electromagnetic steel plate of lamination can form a firm combination (stator iron core) by step up (the concavo-convex joint) that utilizes HAC in the mould.The stator 19 that twines staor winding 31 formation at stator iron core 29 is fixed in the framework 2 by the hot charging cooperation.
Below, the invention process form 2 is described.
Fig. 7 illustrates the motor compressor 1 of form of implementation 2 of the present invention.Fig. 7 illustrates the section configuration same with occasion shown in Figure 1, and difference is through hole 44 is located at the part of framework 2.This through hole 44 is located at projection 38 (contacting parts of convex).By the projection 38 (contacting part of convex) and framework 2 of tack welding ( Star Network welds) by these through hole 44 fixed stators 19.
The external diameter of the stator 19 of the permanent magnet rotary electric machine that uses in motor compressor 1 of the present invention is 105mm, the thick 45mm of lamination.There is shatter test in compressor, does not satisfy specification when the impact when falling makes stator 19 from the hot charging position deflection of framework 2.For this reason, in the part of framework 2 through hole 44 is set, projection 38 (contacting part of convex) and framework 2 by 44 pairs of stators 19 of this through hole carry out tack welding, and be fixing by weld part 43.Like this, can provide the motor compressor 1 that can bear shatter test.
Below, form of implementation 3 of the present invention is described.
Fig. 8 illustrates the motor compressor 1 of form of implementation 3 of the present invention.Fig. 8 illustrates and same section configuration shown in Figure 1, and difference is, in the interior week of framework 2, prevents that with falling member 42 is set to the bottom of stator 19.
