As shown in Figure 4, due to V-shaped part 30 being set in branch-cut bridge Free up Memory 28, each slot side trench part (also referred to as " slot side part ") 34, it is located radially from corresponding slot 24, and it has more path to groove width compared with the width of each flank channel portions (also referred to as " flank part ") 36, this groove width is the width of measuring to the external peripheral surface of following cylinder guiding wall (tubulose guiding wall) 44 from the inner circumferential surface of slot side trench part 34, each flank channel portions (also referred to as " flank part ") 36 is located radially from corresponding toothed portion 22.
In other words, in the annular section 20 of stator core 12, compare with each flank part of annular section 20 of the radially inner side that is positioned at corresponding toothed portion 22, the each slot side part that is positioned at the annular section 20 of the radially inner side of corresponding slot 24 has from the larger width of the external peripheral surface of annular section 20.Particularly, in this example, in the each slot sidepiece office of annular section 20 of radially inner side that is positioned at corresponding slot 24, be set to W1 from the external peripheral surface of annular section 20 to the width of branch-cut bridge Free up Memory 28; At the each flank part place of annular section 20 of radially inner side that is positioned at corresponding toothed portion 22, be set to W2 from the external peripheral surface of annular section 20 to the width of branch-cut bridge Free up Memory 28, width W 2 is less than width W 1.
Further, as shown in Figure 1, through hole 42 axially extends through annular section 20 center.Be integrally formed in the periphery setting along the through hole 42 in annular section 20 of cylinder guiding wall 44 in an insulator 18 (insulator 18 at Z2 side place particularly).In other words, guiding wall 44 axially protrudes around the through hole 42 in the second axle side (Z2 side) of annular section 20, thereby make guiding wall 44 from the inner circumferential surface of annular section 20 inwardly leading thread to isolation, to branch-cut bridge Free up Memory 28 is radially defined as all around the guiding wall 44 between the external peripheral surface of guiding wall 44 and the inner circumferential surface of annular section 20.Further, if needed, the end face 26 of the annular section 20 that guiding wall 44 can be the second axle side (Z2 side) of annular section 20 axially protrudes outwardly.
In stator core 12, as shown in Fig. 2 and 5, guiding piece (winding retainer) 50 is arranged on the end face 48 of the annular section 20 in the first axle side of annular section 20, and another conventionally and in insulator 18 (being the insulator 18 at Z1 side place) is integrally formed.The end face axial ground of the annular section 20 of guiding piece 50 the first axle side (Z1 side) protrudes.
As shown in Figure 1, each winding 14 around a winding in toothed portion 22 several times, is wound around several times around another in toothed portion 22 afterwards, in another in aforementioned toothed portion 22 and aforementioned toothed portion 22 one the circumferential several toothed portion 22 of isolation.Each wound portion of the winding 14 being wound around around corresponding toothed portion 22 is divided and is formed as wound portion and divides (coil) 52.In the time that winding 14 is wound around around toothed portion 22 in the above described manner, each branch-cut bridge 54 is formed between two corresponding winding parts 52.
As shown in figs. 1 and 3, each branch-cut bridge 54 is extended and is directed above the second axle side of annular section 20, that is, be kept along the external peripheral surface of guiding wall 44.Meanwhile, branch-cut bridge 54 is overlapping in the axial direction of annular section 20.Further, the promotion member (for example flywheel) that the part of each branch-cut bridge 54 of extend through branch-cut bridge Free up Memory 28 is not described is pushed in the branch-cut bridge Free up Memory 28 in a side (the Z2 side in Fig. 3) vertically, and this part of branch-cut bridge is axially held in branch-cut bridge Free up Memory 28.
Like this, as shown in Figure 2, the axial outermost portion 56 of all branch-cut bridges 54 is placed in the axial inner side of the outermost portion 58 of all winding parts 52.; in the first embodiment; the height (height of measuring from the axle center of annular section 20) of the outermost portion 56 of branch-cut bridge 54 is set to height H 1, and it is wound around the height H 2 (axial height of measuring from the axle center of annular section 20) of the outermost portion 58 of part 52 lower than (being less than).
Further, as shown in Fig. 2 and 5, the coil termination part 60 of each winding 14 is placed in the first axle side (Z side, it is relative with branch-cut bridge 54) of annular section 20.Directed 50 of coil termination part 60 keeps, and axially protrude on the surface of the insulator 18 of the stator core 12 of guiding piece 50 the first axle side (Z1 side).
Next, explanation is there are to fan electromotor 70 structures of the armature 10 of the first embodiment.
The fan electromotor 70 of the first embodiment showing in Fig. 6 is the radiator settings for the radiator of cooling vehicle the engine room of adjacent vehicle.Fan electromotor 70 comprises stator 72, rotor 74, control circuit device 76 and fan 78.
Two bearing components 84 are contained in tubular portion 82 and support rotating axle 86 rotatably.An axle head of rotation axis 86 protrudes from tubular portion 82 outwardly by hole 88, and hole 88 is formed on the bottom of tubular portion 82.This axle head of rotating shaft 86 is fixed to rotor case 90 center, and rotor case 90 is arranged on rotor 74.
The fan 78 that Fig. 6 shows is integrally set to the external peripheral surface of the cylindrical part 92 of rotor case 90.Fan 78 integrally rotates and produce air-flow in the direction of rotation of fan electromotor 70 with rotor 74.
Next, by the explanation armature 10 of the first embodiment and the function of fan electromotor 70.
First, in order to understand better the function of armature 10 and fan electromotor 70 of the first embodiment, armature 100 that will explanation comparison example.The armature 100 of Figure 31 and 32 display comparison examples.In the following explanation of the armature 100 of comparison example, the parts identical with the first embodiment will represent with identical reference marker, and are no longer described for simplicity.
As shown in Figure 31 and 32, then in the armature 100 of comparison example, branch-cut bridge Free up Memory (crossover relieve space) 28 (seeing Fig. 1) are deleted from the armature 10 of the first embodiment.Therefore,, in the armature 100 of comparison example, branch-cut bridge 54 is overlapping in the axial direction of stator core 12.Therefore, shown in figure 32, the outermost portion 56 of branch-cut bridge 54 along annular section 20 be axially placed in be wound around part 52 outermost portion 58 axially outwardly.; in this comparison example, the height H 1 ' of the outermost portion 56 of branch-cut bridge 54 (axial height of measuring from the axle center of annular section 20) is greater than the height H 2 ' (axial height of measuring from the axle center of annular section 20) of the outermost portion 58 that is wound around part 52.Therefore,, in comparison example, the axial height of armature 100 is adversely increased.
Further, as shown in Figure 31 and 32, different from the armature 10 (Fig. 2) of the first embodiment, in the armature 100 of comparison example, the winding terminal part 60 of each winding 14 is arranged on identical axle side, and branch-cut bridge 54 is arranged on this axle side.Therefore, if each winding 14 is made with relatively large diameter thick winding, the winding terminal part 60 of each winding 14 may be interfered with branch-cut bridge 54, thus the winding operation of overslaugh winding 14 adversely.
On the contrary, in the armature 10 of the first embodiment, branch-cut bridge Free up Memory 28 is arranged in the end face 26 of the annular section 20 in the second axle side (Z2 side) of annular section 20, and the corresponding part of each branch-cut bridge 54 is accommodated in branch-cut bridge spatial accommodation 28.The outermost portion 56 of branch-cut bridge 54 is arranged on (being the height H 1 < height H 2 in Fig. 2) axially inwardly of the outermost portion of the winding part 52 in the second axle side.Therefore, as shown in Figure 3, even overlapping or intersect in the axial direction of annular section 20 when branch-cut bridge 54 and another, also can limit the increase of the axial dimension of armature 10.Like this, can reduce the axial dimension of armature 10.
Further, in the armature 10 of the first embodiment, the radial groove width that branch-cut bridge Free up Memory 28 is formed each slot side trench part 34 (it is positioned at the radially inner side of corresponding slot 24) is less than the radial groove width of each flank channel portions 36 (it is positioned at the radially inner side of corresponding toothed portion 22).Therefore,, due to the appearance of corresponding channel portions 36, branch-cut bridge Free up Memory 28 radially extends to each correspondence position of contiguous corresponding toothed portion 22.The branch-cut bridge 54 of therefore, extending from corresponding toothed portion 22 can be placed in branch-cut bridge Free up Memory 28 in (V-shaped part 30) corresponding position of adjacent teeth part 22.Result, even when branch-cut bridge 54 and another overlapping or intersect in the axial direction of annular section 20, the outermost portion 56 of branch-cut bridge 54 can be placed on the axial inner side of the outermost portion 58 that is wound around part 52 reliably, therefore can effectively limit the increase of the axial dimension of armature 10.
Further, the fan electromotor 70 of the first embodiment has above-mentioned armature 10.Therefore,, due to reducing of the axial dimension of armature 10, the axial dimension of whole motor 70 reduces.
In addition, in the armature 10 of the first embodiment, the coil termination part 60 of each winding 14 is placed in the first axle side (Z1 side) of annular section 20, that is, on the opposite side of annular section 20, it is contrary with branch-cut bridge.Therefore,, even be made into thick winding when each winding 14, also can limit the interference between coil termination part 60 and the branch-cut bridge 54 of each winding 14.As a result, winding 14 can easily be wound around around toothed portion 22, and the winding operation of winding 14 becomes easy.Equally, the guiding wall 44 that the branch-cut bridge 54 of winding 14 is easily had relatively level and smooth external peripheral surface by frictional engagement keeps location, for example, and without starting in described guiding groove as branch-cut bridge 54 is accurately navigated to specification.This also makes the winding operation of winding 14 become easy.
Owing to thering is the armature 10 of the first embodiment, except above-mentioned advantage, can also realize following advantage.; in the armature 10 of the first embodiment; compared with being positioned at the width of flank part of annular section 20 of radially inner side of toothed portion 22; the slot side part that is positioned at the annular section 20 of the radially inner side of slot 24 has larger radial width, and this radial width is the width of measuring to branch-cut bridge Free up Memory 28 from the external peripheral surface of annular section 20.Therefore, compared with being positioned at the width of flank part of annular section 20 of radially inner side of toothed portion 22, the radial width (radial thickness) that is positioned at the slot side part of the annular section 20 of the radially inner side of slot 24 is increased, simultaneously, compared with being positioned at the flank part of annular section 20 of radially inner side of toothed portion 22, it conducts more substantial magnetic flux.Therefore, can limit or reduce the largelyst the increase of core losses and magnet loss, these losses cause due to branch-cut bridge Free up Memory 28 being set in annular section 20.
Further, in the branch-cut bridge Free up Memory 28 of the armature 10 of the first embodiment, each V-shaped part 30 (its radially inner side from annular section 20 is tapered to the radial outside of annular section 20) is set to the corresponding part (it is positioned at the radially inner side of corresponding toothed portion 22) of corresponding annular section 20.Like this, branch-cut bridge Free up Memory 28 can be formed and make each channel portions 34 (it is positioned at the radially inner side of corresponding slot 24) have radial groove width, and this radial groove width is less than the width of the channel portions 36 of the radially inner side that is positioned at corresponding toothed portion 22.
Next, by the explanation armature 10 of the first embodiment and the variation of fan electromotor 70.
In the first embodiment, as shown in Figure 8, multiple cooling through holes 40 can be arranged in the bottom 38 of branch-cut bridge Free up Memory 28 to be upward through the bottom 38 of branch-cut bridge Free up Memory 28 at the axle of annular section 20.Further, multiple cooling through holes can be arranged to extend through the bottom 98 of the rotor case 90 shown in Fig. 6, thereby cooling-air in the time that fan 78 rotates is blown in the inside of rotor case 90.
Owing to thering is said structure, in the time that cooling-air in the time that fan 78 rotates is supplied in the inside of rotor case 90, in the Cooling Holes 40 of cooling-air by the branch-cut bridge Free up Memory 28 shown in Fig. 8.Therefore, winding 14 and bearing components 84 (the seeing Fig. 6) air that can be cooled is advantageously cooling.
Further, in the first embodiment, as shown in Figure 9, position on the protrusion distolateral (a, side of the protruding end of orientation direction wall 44) of the branch-cut bridge 54 that the diameter parts 46 increasing can keep at the external peripheral surface of cylinder guiding wall 44 is integrally formed in cylinder guiding wall 44.
Like this, even for example due to the operational vibration of fan 70, the second axle side (Z2 side) of present dynasty's annular section 20 applies load to each branch-cut bridge 54 so that during towards the second axle side shifting branch-cut bridge 54 of annular section 20, and each branch-cut bridge 54 can advantageously be kept removing (dismounting) to limit each branch-cut bridge 54 from guiding wall 44 by the diameter parts 46 of this increase.
Equally, in the first embodiment, as shown in figure 10, thereby the overall diameter that makes guiding wall 44 that guiding wall 44 can be taper increases towards the second axle side (Z2 side) of annular section 20 from the first axle side (Z1 side) of annular section 20.
Even if there is this structure, when for example operational vibration due to fan 70, while applying load to branch-cut bridge 54 towards the second axle side (Z2 side) of annular section 20, each branch-cut bridge 54 is advantageously limited towards the movement of the protruding end of guiding wall 44, removes from guiding wall 44 thereby advantageously limit branch-cut bridge 54.
Further, changing shown in Fig. 9 in example, it is distolateral that the diameter parts 46 of increase is set to the protrusion of the corresponding branch-cut bridge 54 in guiding wall 44, and integrally form with guiding wall 44.But this can change as follows.
,, in the variation example shown in Figure 11, as substituting of the diameter parts 46 increasing, flange member (as the diameter parts increasing) 62 arranges discretely with guiding wall 44.Flange member 62 shapes are torus, and its external peripheral surface along guiding wall 44 extends.Further, multiple joint depression 63 (being 4 in this variation example) are formed in flange member 62, and multiple joint depressions 63 are configured in a circumferential direction one and connect another and be used as bonding part.As shown in Figure 12 A and 12B, through hole 64 is formed in each joint depression 63 so that axially through flange member 62.
As shown in figure 11, be arranged in such a way in the part of the annular section 20 of the formation stator core 12 of insulator 18 mode of protruding from the bottom 38 of branch-cut bridge Free up Memory 28 with bump bonding 65 as the bump bonding 65 of rod bonding part.In this variation example, four bump bondings 65 in a circumferential direction one connect another ground and arrange.As shown in Figure 12 A, there is swedged rivet 66 (level and smooth cylindrical-type connector pin) and is formed on the far-end of each bump bonding 65.In this variation example, as shown in Figure 12 A and 12B, the rivet 66 of bump bonding 65 is received into respectively in the through hole 64 of flange member 62, so that as shown in figure 11, flange member 62 is arranged on the protruding end of guiding wall 44.Then, in this state, as shown in Figure 12 B, the protruding end of each rivet 66 by hot riveting stickfast in the second axle side (Z2 side), make each joint depression 63 and corresponding bump bonding 65 be engaged with each other and link together, it is distolateral that flange member 62 is fixed to the protrusion of the corresponding branch-cut bridge 54 on guiding wall 44.

Main core slot diapire (circle wall of the radial outward) 259A of each main core slot 257A is from the radially biasing inwardly of pair slot diapire unshakable in one's determination (radially inner side slot wall unshakable in one's determination) 259B of axially adjacent pair slot 257B unshakable in one's determination.Further, between main core slot diapire 259A and secondary slot diapire 259B unshakable in one's determination, form and radially extend step wall 261.Step wall 261 is towards the first axle side (Z1 side) and extend in the imaginary plane of the central axis perpendicular to armature 218.
Core in the laminated core 244 with the first wafer assemblies 244A unshakable in one's determination and the second wafer assemblies 244B unshakable in one's determination forms axial penetration through hole 256.Tubular portion 126 (seeing Figure 14) is contained in through hole 256, thereby makes armature 218 integrally support (seeing Figure 14) by stator case 112.
Further, at the present embodiment, guiding piece 260 has two types.Particularly, as shown in figure 23, the guiding piece 260 (guiding piece 260A) of a type guides corresponding coil termination part 251 (the coil termination part 251A of the winding end portion 250A of corresponding winding 250).Equally, as shown in figure 23, two coil termination parts 251 (the coil termination part 251C of the coil termination part 251B of the winding end portion 250B of winding 250 and the winding start-up portion 250C of winding 250) corresponding to the guiding piece 260 of another kind of type (guiding piece 260B) guiding.
Retainer (holddown groove) 262A is arranged with in guiding piece 260A, and two retainers (holddown groove) 262B, 262C are arranged with on guiding piece 260B.Each retainer 262A, 262B, 262C open and axially extend towards the radial outside of armature 118.The coil termination part 251A press fit of the winding end portion 250A of winding 250 is in the retainer 262A of guiding piece 260A.The coil termination part 251C difference press fit of the coil termination part 251B of the winding end portion 250B of winding 250 and the winding start-up portion 250C of winding 250 is in retainer 262B, 262C.
Further, slot diapire 264 (circle wall of the radial outward of armature 218) is arranged in insulator 246, and each slot diapire 264 limits corresponding slot 263.In an one shaft end office, (the first axle side (Z1 side) of armature 218 is located) has one or two release depression 265 (relief recess) to each slot diapire 264.
As shown in Figure 27 A-27B, each release depression 265 is extended in the axial end 258A of annular section 258 upper shed and in the axial direction of armature 218.Equally, each release depression 265 is arranged in biasing space 267, and biasing space 267 is positioned in the first axle side of step wall 261.Further, each release depression 265A extends axially continuous with the retainer 262A of corresponding guiding piece 260A.Equally, each release depression 265B extension is axially continuous with the retainer 262B of guiding piece 260B.Further, each release depression 265C extends with the retainer 262C of guiding piece 260C axially continuous.
Further, leading edge 269 extends on the slot diapire 264 of each correspondence, discharges depression 265B, 265C and is arranged in aforementioned slot diapire 264.The directed limit 269 of winding start-up portion 250C of winding 250 guides (location and maintenance), thereby makes the winding start-up portion 250C of winding 250 guide (part Figure 28 A) along the socket sidewalls 266 of slot 263.
Next, by function and the advantage of the fan electromotor 70 of the explanation third embodiment of the present invention.
In the fan electromotor 70 of the third embodiment of the present invention, as shown in Figure 23 and 27A-27B, in the shaft end office of each slot diapire 264 (the first axle side (Z1 side) of armature 218 is positioned at this place), one or two discharges that depression 265 is set up and in the end face 258A upper shed of the annular section 258 of armature 218.Coil termination part 251 sides of the axial lead part (, winding end portion 250A, winding end portion 250B and winding start-up portion 250C) of winding 250 are accommodated in the release depression 265 of slot 263.
Therefore, coil termination part 251 sides of the axial lead part of winding 250 are by moderately bending, and do not contact the edge 258B of the end face 258A of annular section 258.Like this, being reduced or preventing of the resilience of each coil termination part 251 so that prevent coil termination part 251 from corresponding guiding piece 260 be not intended to remove.Equally, guide the axial height of each guiding piece 260 of corresponding terminal part 251 to be reduced or to minimize, thereby make the axial dimension of motor be reduced or minimize.
; in the time that each release depression 265 is removed; cause the edge 258B of the end face 258A of the coil termination part 251 side contacts annular sections 258 of the axial lead part of winding 250; in the time that the axial height of guiding piece 260 reduces; coil termination part 251 sides of the axial lead part of winding 250 are bent significantly, cause the increase of the resilience of coil termination part 251.As a result, keep coil termination part 251 to become difficulty with guiding piece 260.Particularly, in relatively large motor, the motor of for example cooling vehicle radiator, the diameter of each winding 250 is relatively large.Therefore,, in the time that winding 250 is significantly bending, keep coil termination part 251 to become difficult with guiding piece 260.On the contrary, in the time increasing the height of guiding piece 260, it is bending that the coil termination part 251 of the axial lead part of winding 250 can have appropriateness.But the axial dimension of motor is adversely increased.
In contrast, in the fan electromotor 70 of the third embodiment of the present invention, as mentioned above, coil termination part 251 sides (, winding end portion 250A, winding end portion 250B and winding start-up portion 250C) of the axial lead part of winding 250 are contained in respectively and discharge in depression 265 to realize appropriateness bending.Therefore, can prevent coil termination part 251 from guiding piece 260 be not intended to remove.Equally, the height of guiding piece 260 can be reduced or minimize, to reduce or minimize the axial dimension of motor.
Further, in the fan electromotor 70 of the third embodiment of the present invention, laminated core 244 be arranged on armature 218 the first axle side place the first wafer assemblies 244A unshakable in one's determination and be arranged on the second wafer assemblies 244B at the second axle side place of armature 218.The main core slot diapire 259A of the first wafer assemblies 244A unshakable in one's determination radially departs from the pair slot diapire unshakable in one's determination 259B of the second wafer assemblies 244B inwardly.
Each release depression 265 is positioned in corresponding biasing space 267, and biasing space 267 is being arranged in the first axle side (the Z1 side of armature 218) of the step wall 261 between main core slot diapire 259A and secondary slot diapire 259B unshakable in one's determination.Therefore, biasing space 267 allows to discharge easily formation of depression 265.
Further, in the fan electromotor 70 of the third embodiment of the present invention, the second slot diapire 259B is positioned at the radial outside (distal side of toothed portion 254) of main core slot diapire 259A.Like this, the thickness (thickness t) of slot diapire 264 parts that contiguous secondary slot diapire 259B unshakable in one's determination arranges diametrically can be made relatively little, to prevent the increase of this part magnetic loss.
Further, as shown in Figure 23 and 24, in the fan electromotor 70 of the third embodiment of the present invention, each release depression 265 is extended continuous with the corresponding retainer 262 of corresponding guiding piece 260 in the axial direction of armature 218.Therefore the part of each winding 250 and the coil termination part 251 of the winding 250 that guiding piece 260 keeps that, are contained in corresponding release depression 265 can be by linear guides in the axial direction of armature 218.Therefore, winding 250 can easily be contained in and discharges in depression 265 and can easily be kept by corresponding guiding piece 260.Like this, can improve the winding operation of winding 250.
Equally, in the fan electromotor 70 of the third embodiment of the present invention, as shown in Figure 23 and 28A-28B, the winding start-up portion 250C of winding is guided (location and maintenance) by the leading edge 269 protruding from slot diapire 264 radial outward, thereby makes the winding start-up portion 250C of winding 250 directed along adjacent socket sidewalls 266.Therefore, can prevent that winding start-up portion 250C significantly separates or swells from socket sidewalls 266 in the time being wound around winding 250 around toothed portion 254.Like this, improved the occupation rate of the winding 250 being wound around around toothed portion 254.
The explanation as above of the function of the fan electromotor 70 of the third embodiment of the present invention and advantage.Here please note that the motor similar to the parts of the fan electromotor 70 of the second embodiment 70 parts realize function and the advantage similar to the parts of the fan electromotor 70 of the second embodiment.Therefore, the function of these parts and advantage no longer illustrate.
