Teeth portion) 81, the winding section 81 makes coil 72 and teeth portion 71b insulate, constitute the conducting wire of coil 72 radially coiling in this around
Line portion 81.In addition, the inner wall part 82 and outside wall portions 83 that the direction that Xiang Congxin 71 leaves extends are respectively arranged on tooth at insulator 80
The internal side diameter and outside diameter of portion 71b.In present embodiment 1, winding section 81 mutually connects with inner wall part 82, winding section 81 and outer
Wall portion 83 also mutually connects.
Inner wall part 82 prevents coil 73 from collapsing (Japanese: collapsing れ Ru) to internal side diameter, and outside wall portions 83 prevent coil 73 to outer diameter
Side collapse.Therefore, inner wall part 82 and the axial height of outside wall portions 83 are higher than the axial height of winding section 81.In addition, for interior
For the height of wall portion 82 and outside wall portions 83, it is more that outside wall portions 83 are generally set to higher than inner wall part 82 situation, in Fig. 4

Figure.Winding when by the core 71 after coiling due to coiling, which tightens, to be reduced so that thickness is laminated with going towards internal side diameter, phase
Tilt angle theta is formed for plane T (contact surface of core 71 and insulator 80 before coiling) orthogonal to the axial direction.
Herein, to tilt angle theta and benchmark tilt angle thetaMAXIt is illustrated.The amount tightened is wound not due to core 71
It can become more than the summation in gap between the stacking of core 71 being made of stacked steel plate, so the maximum value as tilt angle theta
Benchmark tilt angle thetaMAXIt can be found out by following formula 1.
[formula 1]
In above-mentioned formula 1, H [mm] is the stacking thickness of the core 71 as stacked steel plate.X [opening] is the electromagnetism for constituting core 71
The stacking number of steel plate.δ [mm] is the gap (gap between stacking) between the electromagnetic steel plate of stacking.For stator 70
Outer diameter,For the internal diameter of stator 70.For the outer incline angle, θ of present embodiment 1oFor, in order to avoid constituting
The conducting wire of coil 72 is contacted with insulator 80, and becomes the benchmark tilt angle theta that will be found out by formula 1MAXSetting as lower limit value
(θo≥θMAX).In addition, tilt angle theta becomes benchmark tilt angle thetaMAX(θ≤θ belowMAX)。
When core 71 due to winding tightens and when gradient angle, θ, outside wall portions 83 also follow the inclination of core 71 and inside
Diameter rolls oblique tilt angle theta.But the outside wall portions 83 in present embodiment 1 are that have in outside diameter as benchmark before coiling
Tilt angle thetaMAXAbove outer incline angle, θoThe inclined shape of amount, so outside wall portions 83 will not be located at the rotation rail of conducting wire
On road.That is, as shown in figure 5, the internal side diameter of plane T and outside wall portions 83 orthogonal to the axial direction side (inner surface) institute at
Angle be 90 degree or less.Therefore, it can be avoided when based on the coiling of correction winding, what is wound near outside wall portions 83 leads
Line is contacted with outside wall portions 83.
As described above, multiple insulators 80 of electric rotating motivation 60 have outside wall portions 83, described before carrying out coiling
Outside wall portions 83 roll oblique outer incline angle, θ relative to diameter axially outwardo.Therefore, even if insulator 80 follows winding and tightens institute
The stacking thickness change of the core of cause and rolled tiltedly to internal diameter, since outside wall portions 83 roll oblique outer incline angle, θ to outer diameteroAmount,
So being able to suppress the coiling that outside wall portions 83 interfere coil 72.Therefore, according to electric rotating motivation 60, can be avoided be wound in around
The conducting wire in line portion 81 and outside wall portions 83 conflict for main cause the random line of winding and conducting wire surface insulating film damage
Wound.
That is, can be realized high-precision correction winding, so can be realized according to electric rotating motivation 60 and compressor 10
The raising of moyor.In addition, since conducting wire is not contacted with outside wall portions 83, so threading speed high speed can be made, so energy
Enough realize the raising of productivity.The manufacture of the insulating film of conducting wire can also be inhibited to deteriorate, so can be realized mentioning for reliability
It is high.
In the compressor 10 for carrying electric rotating motivation 60, temperature environment in compressor 10 by refrigerant gas or
The influence of the fever of stator 70 etc..Therefore, according to operating condition, the temperature in compressor 10 may be -50 DEG C~150 DEG C, institute
To need to ensure reliability in wide temperature band.For the conducting wire of the coil 72 by the insulating film covering based on resin material
For, it especially must assure that reliability when high temperature, it is necessary to avoid the damage of insulating film when coiling.
In particular, using the mix refrigerant comprising HFO-1123, such as HFC- according to nearest refrigerant trend
When 32 refrigerant, it is desirable that the temperature in reply compressor 10 rises, it is desirable that moyor is improved by high-precision correction winding,
The damage of insulating film when by reducing coiling improves reliability, and the HFO-1123 has the temperature and pressure when compression
The contour property of R410A, R407C, R404A refrigerant that power increase ratio used in the past.
For this point, in present embodiment 1 electric rotating motivation 60 and compressor 10 in, consider caused by coiling
The deformation of core 71 makes the inclination outer incline angle, θ in advance of outside wall portions 83o, so it can be precisely corrected winding, so
It can be realized the raising of moyor.In addition, can prevent insulating film when coiling from damaging, so improving reliability.Cause
This, compressor 10 is able to use the unitary system cryogen being made of HFO-1123 or the mix refrigerant comprising HFO-1123
Deng as the refrigerant recycled in refrigeration cycle.
In addition, being configured to the entirety of outside wall portions 83 in outer incline angle, θ in the example of Fig. 4 and Fig. 5o, but can also be with
It is configured to the side (contact surface with coil 72) of the only internal side diameter of outside wall portions 83 in outer incline angle, θo.That is, outside wall portions 83
Section for example may be cone cell.In addition, the side of the internal side diameter of outside wall portions 83 is also possible to the curved surface to outer diameter lateral bend.I.e.
Make also prevent the conducting wire for constituting coil 72 from contacting with insulator 80 using above-mentioned each structure.
Alternatively, it is also possible to be configured to outside wall portions 83 internal side diameter side only with constitute coil 72 conducting wire conflict one
Part is in outer incline angle, θo.That is, the contact portion of the front end of such as outside wall portions 83 and the outside wall portions 83 and coil 72 can also be with
In different tilt angles, in addition, the internal side diameter of outside wall portions 83 and the side of outside diameter are also possible to curved surface.Also can in this way
Prevent conducting wire from conflicting with insulator 80.But the thickness of outside wall portions 83 needs considering the strong of tension when being able to bear coiling
It is set on the basis of release property and burn when degree and molding etc..
[embodiment 2]
Then, it is based on Fig. 6 and Fig. 7, the electric rotating motivation of present embodiment 2 is illustrated.Fig. 6 and Fig. 7 difference

(effects of Embodiments 1 to 5)
Herein, 4~Figure 17 referring to Fig.1, be described in more detail by above embodiment 1~5 electric rotating motivation and
The effect that compressor obtains.Figure 14 and Figure 15 is in the construction for the stator for showing schematically that previous compressor contains respectively
The longitudinal section view of state before coiling and after coiling.Figure 16 is inner wall part and the outside wall portions institute for the rotor of explanatory diagram 15
The longitudinal section view for the project being related to.Figure 17 is the longitudinal section view of project involved in winding section for the rotor of explanatory diagram 15.
It is illustrated firstly, tightening to winding.The core 71 being made of stacked steel plate is that multiple electromagnetic steel plates are laminated
And constitute, so generating gap delta between several stackings between each electromagnetic steel plate.In coiling, it is applied to the tension conduct of conducting wire
The external force of compressed core 71 plays a role in the axial direction, so gap delta narrows between stacking, so, it is upper with the total backlash amount of core 71
Limit, shrinks in core 71.The contraction is to wind to tighten.In addition, coil 72 is applied only to the teeth portion 71b of core 71, so
Winding deflation amount becomes larger from back yoke portion 71a to the front end of teeth portion 71b, so core 71 becomes the inclined shape of radially inward.This
Outside, as described above, tightening in winding has after the time point winding deflation amount stabilization of coiling first layer, the second layer substantially
Such feature is not changed.
As the method for inhibiting the winding of core 71 to tighten, it is known that following method: being equipped in the electromagnetic steel plate for constituting core more than 71
The circle of a point or caulk (Japanese: カ シ メ) portion of V-shaped apply pressure by punching press etc. in stacking to be held back
Seam, to be fixed on the two radial and axial directions.But even if using the above method, since pressure discharges
Rebound afterwards, so being difficult to tighten winding as 0.In addition, it is also known that by increasing the intrusion or quantity of caulking, from
And caulk power is improved, and inhibit rebound, the method for reducing gap between stacking, but in the intrusion or quantity for increasing caulking
In the case of, the axial eddy current for increasing and generating in stacked steel plate in the driving of electric rotating motivation, moyor can be generated
Decline such project.Therefore, it is desirable to mitigate electric rotating motivation as the above embodiment 1~5 for the influence that winding tightens.
In addition, the outside wall portions 983 of insulator 980 are preferably parallel with swing-around trajectory R when coiling.Therefore, in the past, such as Figure 14
It is shown, in the state of before coiling, insulator 980 is formed in the mode for keeping outside wall portions 983 parallel with swing-around trajectory R.But
In winding process, winding is generated as described above and is tightened, for the shrinkage of core 71, internal side diameter is bigger than outside diameter.Therefore,
It is also tilted radially therewith in the posture for the insulator 980 that one end of core 71 and the other end are arranged as winding stand.That is,
As shown in figure 15, winding section 981, inner wall part 982 and outside wall portions 983 also tilt the axial end face of core 71 relative to it is axial just
The amount for the tilt angle theta that the plane T of friendship is in.
Therefore, in conventional structure, in coiling, in the conducting wire 72a for constituting coil 72 by near outside wall portions 983
When (referring to Fig.1 6), conducting wire 72a conflicts with insulator 980 at high speed, so being unable to control the movement of coiling, can not be corrected
Winding.In addition, due to conducting wire 72a conflicts with outside wall portions 983 and can damage wires 72a insulating film, so there are productivity,
The project of reliability these two aspects.Further more, in conventional structure, inner wall part 982 with the internal diameter of stator 70 it is protruded above and with
Rotor 61 contacts.In addition, as shown in figure 17, the winding that winding section 981 follows core tightens and tilts, so when generating coiling
The component TSd of tension TS and the direction slid to coiling in the axial direction.Therefore, the conducting wire 72a of coiling is to the direction of component TSd
It skids, coiling collapse occurs.
For this point, according to the electric rotating motivation and compressor in the respective embodiments described above, due to multiple insulators
80,180,280,380 and 480 have outside wall portions, and before coiling, which tiltedly sets in advance relative to the inclination of diameter axially outward
Fixed outer incline angle, θo, so even if insulator 80,180,280,380 and 480 follows the core 71 caused by winding tightens
Stacking thickness change and rolled tiltedly to internal diameter, outside wall portions 83 and 383 also roll oblique outer incline angle, θ to outer diameteroAmount, institute
The damage that can tiltedly prevent from constituting the conducting wire 72a of coil 72 is rolled to internal diameter to be able to suppress outside wall portions due to winding tightens
Wound etc..
In addition, the respective embodiments described above are the preferred concrete example in electric rotating motivation and compressor, guarantor of the invention
Shield range is not limited to these modes.For example, in the respective embodiments described above, with benchmark tilt angle thetaMAXOn the basis of, setting
Outer incline angle, θoAnd tilted angle, θi, however, not limited to this, can also be to benchmark tilt angle thetaMAXIn addition
On the basis of value obtained from subtracting defined threshold value (threshold value determined according to shrinkage of gap delta between stacking etc.), setting is outer
