To form multiple layers in same winder 80.In addition, ensured by insulation division 32 between winding portion 50 and unshakable in one's determination 20 tooth 22
Insulating properties.
In addition, in the present embodiment, such as while stretch aluminium using tension force as defined in coil winder (not shown) application
Line 81, while aluminum steel 81 is wound up into winder 80, so as to form winding portion 50.Thereby, it is possible to closely roll up winding portion 50
It is wound in the inclined plane 82 of the insulation division 32 of winder 80.It is here, right by the stop-motion body 44 and stop-motion body 33 of bobbin 30
The positioning that winding portion 50 is entered on the RA of conduct direction.In addition, tension force during with than the wire for being commonly wrapped about being made up of copper cash is lower
Tension winding aluminum steel 81.
As shown in figure 5, form the circumferencial direction CR width of the tooth 22 of winder 80 from core body 21 laterally with it is unshakable in one's determination this
The opposite side of body 21 (side of stop-motion body 44) gradually expands.In addition, sandwich the insulation division 32 of the tooth 22 similarly, its circumferencial direction
CR width laterally gradually expands from bobbin body 31 with the opposite side of bobbin body 31 (side of stop-motion body 44).
That is, winder 80 has with the identical shape of tooth 22, and the width W2 for being configured to the side of stop-motion body 44 is more than bobbin
The width W1 of the side of body 31.Circumferential direction thickness that form winder 80, the insulation division 32 of bobbin 30 is from internal side diameter towards outer
Footpath side is fixed.The circumferential direction thickness of insulation division 32 depends on required insulating strength, the angle of inclination of insulation division 32 and tooth
22 angle of inclination is identical.Moreover, in winder 80, since the winding start point S of the side of bobbin body 31, to footpath direction RA
First layer of the circle of the side of stop-motion body 44 in outside around terminal E (showing winding direct of travel with arrow in Fig. 5) winding aluminum steels 81.
Based on these structures, the winding portion (power coil) 50 being made up of the aluminum steel 81 in winder 80 is outside from its internal side diameter
Footpath side width becomes big and dip-parallel with bobbin 30.That is, the winding portion (power coil) 50 being winding and installed on tooth 22
Circumferential direction width is smaller in internal side diameter, larger in outside diameter.
On the other hand, as shown in Fig. 2 the core body 21 of iron core 20 is fixed on hood 2 such as by bolt
Inner side.Hub 4 is installed in the end of the crank axle 3 of engine (not shown).Therefore, the hub 4 is when engine is run and crank
Axle 3 rotates together.
In addition, rotor 60 across defined gap setting in the footpath direction RA of stator 10 outside.The rotor 60 has：Cylinder
Portion 61, be formed as circular on circumferencial direction CR；And wall portion 64, the side for the direction of principal axis AX for closing this tin portion 61 are opened
Mouthful.Cylinder portion 61 and wall portion 64 are formed integrally with each other.The fixed hub 4 in wall portion 64.
On the inwall in cylinder portion 61, along circumferencial direction CR it is equiangularly spaced be provided with multiple magnet (permanent magnet)
62.In the present embodiment, the side that the plurality of magnet 62 is alternately opposite with the direction of its magnetic pole (N poles, S poles) on the RA of footpath direction
Formula is set, and is provided with 12 magnet 62 altogether.Moreover, as shown in figure 1, cylinder portion 61 outer peripheral face a part formed with prominent
Portion 63.
In a manner of the outside for the footpath direction RA that the cylinder portion 61 for making stator 60 is located at iron core 20, the wall portion 64 is fixed on hub
On 4.Thus, the top of supply line of the tooth 22 of iron core 20 is in the position opposed with magnet 62.Rotor 60 is when engine is run and bent
Arbor 3 and hub 4 rotate together.When rotor 60 rotates, in insulation division 32 opposed with magnet 62, being formed at covering tooth 22
Induced electromotive force is produced in winding portion 50 in (winder 80).As a result, produce electric current in winding portion 50.In winding portion
Caused electric current is supplied via connection winding portion 50 and the output cord (wire harness) 5 (referring to Fig. 2) of vehicle side electric circuit in 50
It is given to the electrical load of battery and the headlamp of cart etc..So, the generator 1 of present embodiment is the hair of outer-rotor type
Motor.
In the footpath direction RA of rotor 60 outside, specified gap is provided with turn-sensitive device 70.Turn-sensitive device 70
The output signal corresponding with the rotation position of teat 63 when rotor 60 rotates.The signal is passed to not shown via wire harness 71
Electronic control unit (hereinafter referred to as " ECU ").Thus, ECU is capable of detecting when the rotation position i.e. rotation of crank axle 3 of rotor 60
Indexing is put.
So, according to the electric rotating machine of present embodiment, following various action effects can be obtained.
Firstly, since aluminum steel 81 has been used in the wire rod of multiple winding portion 50 of stator (fixed body) 10 is formed, therefore,
The weight of generator itself can be mitigated, also, compared with using by the situation for the wire that copper cash is formed, additionally it is possible to significantly reduce
Component costs.
In addition, as shown in figure 5, the circumferencial direction CR width of the winder 80 of winding aluminum steel 81 is configured to, from aluminum steel 81
The winding start point S of first layer to the winding end E of first layer, gradually expands to winding direct of travel, if first layer etc.
Odd-level, then it is that outside gradually expands from bobbin body 31 to footpath direction.
Therefore, the face of the winding aluminum steel 81 of winder 80 tilts relative to winding direct of travel, inclined plane 82 is formed, by rolling up
Caused by line machine by the fastening force that aluminum steel 81 is fastened in winder 80 be divided to the direction D1 parallel with inclined plane 82 and
The direction D2 orthogonal with inclined plane 82.Therefore, the direction D1 parallel with inclined plane 82 fastening force can resist is produced by coil winder
The tensile force F of raw aluminum steel 81.
In any position of the regulation volume number of the first layer of winding portion 50, the tensile force F of coil winder acts on winding all the time
Direct of travel, still, because the circumferencial direction CR width of winder 80 (tooth 22, insulation division 32) is compared with the part of previous winding
Become big, therefore movement of the winding portion 50 to winding direct of travel is suppressed, as a result, even if with lower than wire (copper cash)
Power winds aluminum steel 81, winding portion 50 also can be fitly wound, without entanglement occurs in the winding of first layer.It is moreover, logical
After the winding for fitly winding first layer, can also fit in preceding layer after the second layer, thus all layers formed it is neat around
Group, the external diameter of stator 10 can be made to collect during with using wire (copper cash) in identical size.That is, the winding of winding portion 50 rises
Point is preferably that the most narrow part of the circumferential direction width of winder 80 is internal side diameter.Moreover, the winding direct of travel of winding portion 50 is excellent
Elect as towards the circumferential direction width of winder 80 and become big direction.
Further, due to can with relatively low tension winding aluminum steel 81, therefore can prevent caused by tension force elongate and
Fracture.The tensile strength of especially aluminum steel is only several points of a degree of the tensile strength of copper, therefore, from the viewpoint for preventing fracture
From the point of view of, it is also desirable to tensile stress when winding aluminum steel 81 is reduced to the one of several points of copper cash.
Aluminum steel 81 is fixed to one another by the winding portion 50 that winding is installed on winder 80 after winding is installed by binding agent etc.,
And bonded with bobbin 30.
As shown in fig. 6, when connecting multiple winding portion 50 (coils) with an aluminum steel 81, winding portion 50 and winding are being crossed over
Connecting line 83 be present in the part between portion 50.That is, it is present in the winding end part Z of some winding portion 50 and adjacent winding
Aluminum steel 81 between the winding start point part X in portion 50 is connecting line 83.
In connecting line 83, the initial winding start point and last winding that an aluminum steel 81 is wound to winding portion 50 are whole
Point is so-called lead-out wire, and lead-out wire is directly or indirectly with being connected such as wire harness (such as output cord 5) of external circuit even
Connect.Or, it is assumed that in the case where winding portion 50 is three equal polyphase windings, though not illustrating in detail, connecting line 83 is in star
Neutral point is connected in type wiring.
As described above, the magnet-type generator 1 involved by the application be installed in cart etc. engine or its near,
Therefore easily it is passed vibration.If connecting line 83 is not fixed, it is likely that because the vibration causes connecting line 83 to disconnect,
Or the dielectric film of connecting line 83 is scratched so as to cause electrical short.
Therefore, for the foregoing reasons, it is preferably, by the less connecting line 83 of tensile stress being applied in when winding with stable
State be bonded and fixed at bobbin body 31 of such as bobbin 30 etc. securely.
Moreover, it is that the both ends of connecting line 83 and winding portion 50 are steady that the condition of connecting line 83, which is adhesively fixed, with stable state
It is fixed fixed, wherein, the side at the both ends of connecting line 83 is winding start point part X, and opposite side is winding end part Z.That is, if
The neat winding of the first layer of winding portion 50 is unstable, then binding agent will not comparably permeate, and fixation is unstable.If first layer
Fixation it is unstable, then the fixation for the winding start point part X being connected with connecting line 83 can become unstable, the fixation of connecting line 83
Also it can become unstable, if moreover, the fixation of first layer is unstable, the winding portion 50 being winding and installed on the first layer
Outermost fixation can also become unstable.Because outermost winding end part Z is also connected with connecting line 83, therefore,
If outermost fixation is unstable, the fixation of connecting line 83 still can become unstable.It follows that make winding portion 50
The neat winding of first layer is stably very important.
As described above, in this application, winding portion 50 can be fitly wound, without occurring in the winding of first layer
Entanglement.Moreover, the winding by fitly winding first layer, the second layer can also fit in preceding layer, therefore all layers later
Neat winding is formed, is moved so as to suppress connecting line 83 because of aerial distribution wire and vibration.As a result, it will can connect
Line 83 is bonded and fixed at bobbin body 31 of such as bobbin 30 etc. with stable state securely.
Further, aluminum steel 81 has the property for being easier stretching.If the fixation of winding portion 50 is unstable, it is likely that
Aluminum steel 81 can be caused to elongate, it is undesirable that such case occur.Specifically, if aluminum steel 81 elongates, line footpath can reduce, electricity
Resistance can increase, it is possible to the temperature of hydraulic performance decline or winding portion 50 can be caused to rise.
As described above, in this application, due to can stably fix winding portion 50, therefore it can prevent aluminum steel 81 from drawing
It is long, being capable of rejection decline and the temperature rising of winding portion 50.
As described above, bobbin 30 divides half-and-half the segmentation cut construction (bobbin dividing body to be front and rear on its direction of principal axis AX
30A、30B).On in view of direction of principal axis of the bobbin 30 at itself caused deviation and iron core 20 direction of principal axis on produce
Deviation on the basis of, the direction of principal axis AX's of bobbin 30 is dimensioned to, sandwich iron core 20 in the state of, in cutting part
The composition surface one divided is shaped as gap, so that in the state of the iron core 20 including being sandwiched from direction of principal axis AX both sides comprising tooth 22,
Make segmenting edge part no matter in no instance can mutual laminated.Further, since bobbin 30 is to pass through resin forming
Formed, therefore there is the pattern draft as caused by mould, also, due to also depositing deformation (bending) after shaping, therefore have
There is the shape opened slightly outwards.
In the construction of above-mentioned bobbin 30, such as applying higher tension force to wire and by Wire-wound into winding portion
In the case of, wire is possible to that tooth 22 can be directly contacted in the gap of partitioning portion.Moreover, the insulation in wire covers hair
In the case of raw breakage, it is possible to short circuit can occur.Further, since the higher tension force of the wire of winding, it is possible to can be online
The segmenting edge part of coil 30 or corner rupture.
Further, above-mentioned gap is not to be made only in the insulation division 32 of bobbin 30, in be formed at insulation division 32 and line
Gap, such as the winding in winding portion 50 are also formed with end, tabular the stop-motion body 44 of the opposite side of coil body 31
In the case that terminal E is located at the side of stop-motion body 44, such as when applying higher tension force to wire and having carried out winding, at winding end E
Wire be possible to be in invade before state between the wire and stop-motion body 44 that be wound, be still possible to occur
Short circuit or wire elongate.
However, according to the electric rotating machine of present embodiment, due to can be with relatively low tension winding aluminum steel 81, therefore online
Aluminum steel 81 can not possibly directly contact tooth 22 in the gap of the partitioning portion of coil 30, in addition, in the segmenting edge of bobbin 30
The possibility step-down that part and corner rupture.Further, the possibility that aluminum steel 81 elongates is relatively low.
In addition, according to the electric rotating machine of present embodiment, tension force during due to winding is relatively low, thus aluminum steel 81 relative to
The tolerance for the cold and hot pressure being applied in use environment is improved.Its line expansion system compared with conventional copper cash of aluminum steel 81
Number is larger.That is, relative to the toothed portion using iron as main component, linear expansion coefficient differs greatly.Therefore, in low temperature
When, the winding portion 50 being made up of aluminum steel 81 is shunk larger, it is possible to can invade toothed portion.However, during based on relatively low winding
Tension force, pressure now will not be excessive.Further, although the electric rotating machine of present embodiment is equipped on engine and quilt
Apply larger vibration, still, for the foregoing reasons, overall pressure is smaller, can suppress the damage to caused by the grade of aluminum steel 81
Evil.

Circumferencial direction CR width into the tooth 22 of winder 80 is as usual fixed on the RA of footpath direction.
On the other hand, only sandwich the circumferencial direction CR width of the insulation division 32 of the tooth 22 from bobbin body 31 laterally with
The opposite side of bobbin body 31 (side of stop-motion body 44) gradually expands.Therefore, winder 80 has the insulation division with bobbin 30
32 identical shapes, its net shape are similarly configured to first embodiment, and the width W2 of the side of stop-motion body 44 is more than coil
The width W1 of the side of frame body 31.
In the case of the second embodiment, can be directly using conventional iron core 20.Implement in addition, playing with first
