And, each embedded conductor 50a, 50c are carried out branch, expose the back side at circumferential one of the 2nd circuit board 45 distolateral 2 flange part 45b of place.Embedded conductor 50e is also carried out branch, expose the back side at circumferential another 2 distolateral flange part 45b of place of the 2nd circuit board 45.These embedded conductors 50a, 50c, 50e are adjacent to the wall at back casing 3, and are electrically connected respectively by the fastening force of construction bolt 47.
The control device 30 that constitutes is like this clamped and be fixed on the end face of back casing 3 by 3 construction bolts 47, be configured to fan-shaped in fact toward the periphery of axle 5.Then, installation is had the exciting current control circuit 26 of exciting current of the control circuit circuit board 20 of control circuit 19 of the customization IC of power controlling MOSFET37,38 action or these elements of driver and built-in control magnet exciting coil 7 or the brush carrier 14 of capacitor 22, be configured in the notch of the fan-shaped in fact of control device 30.
And, will constitute the drain electrode of each power MOSFET 37 of upper arm 31,33,35, be electrically connected lead-out terminal bolts 48 by the 1st heating panel 39, and by binding post 46 brush carrier 14 of packing into.With constituting the source terminal 38S of each power MOSFET 38 of underarm 32,34,36, be electrically connected to back casing 3 by embedded conductor 50a, 50c, 50e.
Again, will constitute the source terminal 37S of each MOSFET37 of upper arm 31,33,35, and be electrically connected to the 1st to the 3rd respectively and separate heating panel 41～43 by the face that exposes that exposes embedded conductor 49a, 49c at the back side of the flange part 44b of the 1st circuit board 44,49e.Then, the lead-out wire (exchanging wiring 21) with U phase coil, V phase coil and the W phase coil of armature coil 11 is welded to the 1st to the 3rd respectively and separates heating panel 41～43.
And with source terminal 37S, 38S and gate terminal 37G, the 38G of power MOSFET 37,38, the exposed division of circumferential two ends of the 1st and the 2nd circuit board 44,45 by embedded conductor 49a～49f, 50a～50f is electrically connected to control circuit 19.
Therefore, when the fan 12 at rear being driven into rotation, cooling air is drawn onto in the cover cap 18 from suction hole 18a along with the rotation of rotor 6.So, be drawn onto cover cap 18 interior cooling airs and flow in the back casing 3, and, discharge from steam vent 3c because of fan 12 is bent to centrifugal direction from suction hole 3b.
At this moment, cooling air is mobile like that shown in the No.1 Fa～Fd of arrow among Fig. 1.That is, shown in the No.1 Fa of arrow, the cooling air that flows into from the suction hole 18a of the end face that is opened in cover cap 18 flows toward radially inner side along the surface of the base portion 39a of the 1st heating panel 39, passes through between the 1st heating panel 39 and spools 5, and flows to back casing 3 sides.And shown in the No.1 Fb of arrow, the part cooling air from the suction hole 18a of the end face that is opened in cover cap 18 flows into passes through between the 1st heating panel 39 and the 2nd heating panel 40, and flows to back casing 3 sides.
Again, shown in the No.1 Fc of arrow, the cooling air from the suction hole 18a of the side that is opened in cover cap 18 flows into passes through between the 1st heating panel 39 and the 2nd heating panel 40, and flows to back casing 3 sides.Again, shown in the No.1 Fd of arrow, the part cooling air from the suction hole 18a of the side that is opened in cover cap 18 flows into passes through between the wall of the 2nd heating panel 40 and back casing 3, and mobile toward radially inner side.So the cooling air that circulates in each wind path flows in the back casing 3 by suction hole 3b, and because of fan 12 is bent to centrifugal direction, discharges from steam vent 3c.Thus, make power MOSFET 37 and 38, the 1st and the 2nd heating panel 39 and 40,20 coolings of control circuit circuit board, and then make the rear coil terminal and the exhausting window joint-cutting 3a cooling of armature coil 11.
When the fan 12 in the place ahead is driven into rotation, cooling air is drawn onto in the procapsid 2 from suction hole 2b again.So, be drawn onto procapsid 2 interior cooling airs and be bent to centrifugal direction because of fan 12, discharge from steam vent 2c.Thus, make the place ahead coil terminal and the exhausting window joint-cutting 2a cooling of armature coil 11.
According to this execution mode 1 and since with the 1st heating panel the 39, the 1st circuit board the 44, the 2nd heating panel 40 and the 2nd circuit board 45 axle 5 axially line up 1 layer, therefore can dwindle the axial dimension of control device 30, seek the miniaturization of motor generator for vehicle 1.
And, owing to can dwindle the axial dimension of control device 30, even therefore under the restriction of the limited axial dimension aspect of motor generator for vehicle 1, also can guarantee the wind path of enough cooling airs, thereby guarantee to load the abundant cooling of the 1st heating panel 39 and the 2nd heating panel 40 of the power MOSFET 37,38 that should cool off.Again, can be in limited axial dimension, fin is arranged to guarantee toward mode such as extend axially the optimum surface area and the volume of the 1st heating panel and the 2nd heating panel 39,40 from the 1st heating panel 39 and the 2nd heating panel 40.
And, about the Radial Flow of cooling air, because therefore cooling air can effectively dispel the heat along the moving non-interference of two surface currents of the 1st heating panel 39 and the 2nd heating panel 40.
Again and since cooling air not sluggishly between two faces, the 1st heating panel 39 and the 2nd heating panel 40 of the 1st heating panel 39 so two surface currents of the 2nd heating panel 40 moving, so windage is little, makes the property cooled off raising, and can reduce wind noise.
And, owing to form ventilation hole 51a, 51b, make in its table that connects the 1st heating panel 39 and the 2nd heating panel 40, therefore the cooling air toward axial and Radial Flow circulates in ventilation hole 51a, 51b.Therefore, windage is little, can make air quantity big, and can reduce wind noise.
Again, owing between the 1st heating panel 39 with different current potentials and the 2nd heating panel 40, form the space, and will separate between the two with the base portion 44a (being insulating component) of the 1st circuit board 44, therefore not having foreign matter or conductivity attachment is detained, guarantee high-insulativity, and prevent electric leakage or galvanic corrosion between the different potentials.
And because lead-out terminal bolt 48 reaches the axial outside from the rear end of motor generator for vehicle 1, so under the rear view of vehicle situation of having living space, it is convenient to install with the connecting wiring of storage battery 23 exterior parts such as grade.
Because the 2nd heating panel 40 is positioned at the outside diameter of the 1st fin 39, therefore make things convenient for being electrically connected of armature coil 11 of stator 9 again.
And, owing to, clamp and be fixed on with being integrated the end face of back casing 3 by construction bolt 47, so obtain high vibration resistance with the 1st and the 2nd heating panel 39,40 and the 1st and the 2nd circuit board 44,45 state after with assembling.
The 2nd heating panel 40 is fixed on the end face of back casing 3 by the flange part 45b of the 2nd circuit board 45 again.Therefore, because the heat of power MOSFET 38 arrives back casing 3 by the 2nd heating panel 40 and flange part 45b heat conduction, so power MOSFET 38 is effectively cooled off.
And, the surface of base portion 45a is to separate the position of the installed surface of fin 41～43 with one side with the 1st to the 3rd, expose on the surface in the zone of the base portion 45a corresponding another of embedded conductor 50a～50f is distolateral with the source terminal 38S of power MOSFET 38 and gate terminal 38G, and the face that exposes that the source terminal 38S and the gate terminal 38G of power MOSFET 38 is welded on corresponding embedded conductor 50a～50f.Therefore, source terminal 38S and gate terminal 38G and embedded conductor 50a～50f that can direct and simple and easy connection power MOSFET 38, and can miniaturization.
Again, embed molding and embedded conductor 50a, 50c, 50e that the source terminal 38S of power MOSFET 38 is electrically connected, it is exposed at the back side of flange part 45b, and utilize the fastening force of construction bolt 47 to make it contact the end face of back casing 3 at the 2nd circuit board 45.Therefore, do not need to connect the connection electrode member of embedded conductor 50a, 50c, 50e and back casing 3, reduce the number of components of this part, can reduce weight and cost, and simplify the connection operation.Therefore the ground of also back casing 3 being used as motor generator for vehicle 1 does not need to have the electrode member of negative potential, reduces number of components, can reduce weight and cost.Again owing to the source terminal 38S of power MOSFET 38 is connected to back casing 3 by embedded conductor 50a, 50c, 50e, the hot direct heat of power MOSFET 38 is transmitted to the back casing 3 of low temperature, stay out of air, thereby the temperature that suppresses power MOSFET 38 raises.
Here, the flange part 39b that lead-out terminal bolt 48 usefulness are installed is arranged to extend to radial outside from the base portion 39a of the 1st heating panel 39, is located on the 2nd heating panel 40, therefore reduce the area of dissipation of the 1st fin 39.Therefore, preferably make the radial width of base portion 39a of the 1st heating panel 39 greater than the radial width of the base portion of the 2nd heating panel.At this, it is big that the area of dissipation of the 1st heating panel 39 becomes, and therefore prevents to install the cooling deterioration of the 1st heating panel 39 that lead-out terminal bolt 48 causes.Therefore, the cooling effectiveness of the 1st heating panel 39 equals the cooling effectiveness of the 2nd heating panel 39,40 in fact, can with the 1st with the 2nd heating panel 39,40 on the power MOSFET 37,38 installed be cooled to identical in fact temperature.Because it is the rigidity of the 1st heating panel 39 is big, therefore favourable on intensity again to external force from external connection line.Therefore, even the stress of external force when storage battery 32 exterior parts such as grade are installed to lead-out terminal bolt 48 or vibration external force also can prevent the state of affairs of the 1st heating panel 39 fractures in the 1st heating panel 39.
Fig. 9 is the longitudinal section of main assembly that the motor generator for vehicle of embodiment of the present invention 2 is shown, Figure 10 is the rear end view drawing of seeing the state that unloads cover cap from the rear of the motor generator for vehicle of embodiment of the present invention 2, Figure 11 is the vertical view of control device that the motor generator for vehicle of embodiment of the present invention 2 is shown, Figure 12 be the D-D of Figure 10 to looking cutaway view, Figure 13 is that the E-E of Figure 10 is to looking cutaway view.
Among Fig. 9 to Figure 13, the cross section that the 2nd circuit board 45A forms base portion 45a and flange part 45b composition had the fan-shaped in fact of L shape at control device 30A.And, the 1st to the 3rd separate heating panel 41～43 and line up fan-shaped in fact what constitute the 2nd heating panel 40, and show out with the 2nd circuit board 45A surface and the internal perisporium that the ground mould-forming gets separately that be integrated.So, line up surface that the 1st to the 3rd of fan-shaped in fact separates heating panel 41～43 for the surperficial same position of the base portion 45a of the 2nd circuit board 45A, cover the 1st to the 3rd back side of separating heating panel 41～43 by flange part 45b.
Again, embed 6 embedded conductor 50a～50f of molding at the 2nd circuit board 45A, but be partially submerged into conductor 50a, 50c, 50e and near the connection protuberance 54 of the end face that is erected to be arranged at back casing 3, reach radial outside, to replace exposing the back side at flange part 45d from base portion 45a.And, the extension 52 of embedded conductor 50a, 50c, 50e is clamped and is fixed on the connection protuberance 54 of back casing 3 respectively by screw 53.
Other forms identical with above-mentioned execution mode 1.
Among this motor generator for vehicle 1A, the 2nd circuit board 45A being separated heating panel 41～43 on the end face of back casing 3 with the 1st to the 3rd, is that center configuration becomes fan-shaped in fact with the axle center of back casing 3.And it is relative with the flange part 45b of the 2nd circuit board 45A that the 1st circuit board 44 is configured to separate heating panel 41～43 across the 1st to the 3rd.Also dispose the 1st heating panel 39, each flange part 39b is stated from the flange part 44b of the 1st circuit board 44, and make the interior all side of base portion 39a near the base portion 44a of the 1st circuit board 44.
And, the flange part 45b of the circumferential flange part 44b except that circumferential another 3 places distolateral of the flange part 39b except that circumferential another distolateral 3 places of the 1st heating panel 39, the 1st circuit board 44, the 1st to the 3rd separation heating panel 41～43 circumferential one distolateral and the 2nd circuit board 45A separately respectively at axial overlap, and is fixedly clamped at back casing 3 by construction bolt 47.Lead-out terminal bolt 48 also is installed, is made it connect circumferential another distolateral flange part 39b of the 1st heating panel 39, reach the axial outside from cover cap 18 from rear side.And, by screw 53 extension 52 of embedded conductor 50a, 50c, 50e is clamped and be fixed on back casing and connected protuberance 54 in 3 minutes.Binding post 46 is contained between the head and flange part 39b of lead-out terminal bolt 48 again.The flange part 44b of the 1st circuit board 44 is contained in lead-out terminal bolt 48 separates between the heating panel 43, and both are electric insulating state (not shown) with the 3rd.
Like this among the motor generator for vehicle 1A of Gou Chenging, circumferential whole zone at the 2nd circuit board 45A, flange part 45b is close to the end face of back casing 3, except that cooling airflow Fa～Fc shown in Figure 1, also utilize flange part 45b that back casing 3 is conducted heat, make control device 30A cooling by the 2nd circuit board 45A.
In this execution mode 2 and since with the 1st heating panel the 39, the 1st circuit board the 44, the 2nd heating panel 40 and the 2nd circuit board 45A axle 5 axially line up 1 layer, therefore can dwindle the axial dimension of control device 30A, obtain the effect identical with above-mentioned execution mode 1.
And, identical with above-mentioned execution mode 1 and since with the 1st heating panel the 39, the 1st circuit board the 44, the 2nd heating panel 40 and the 2nd circuit board 45A axle 5 axially line up 1 layer, so windage reduces, it is big that the air quantity of cooling air becomes.So, the heat of power MOSFET 38 from the flange part 45b heat conduction of the 2nd heating panel 40 by the 2nd circuit board 45A to back casing 3, by the exhausting window joint-cutting 3a air cooling that is cooled.Therefore, the flow of cooling air increases, and the amount of heat transfer to back casing 3 is increased, so the reinforcement that both multiply each other increases the heat exchange amount from back casing 3, the temperature that suppresses control device 30A raises.
Again,, therefore obtain high vibration resistance, and cut down number of components, be convenient to install because the 2nd heating panel 40 (the 1st to the 3rd separates heating panel 41～43) must be integrated with the 2nd circuit board 45A mould-forming.
And, the flange part 45b of circuit board 45A is formed fan-shaped in fact.Therefore, the heat of power MOSFET 38 is delivered to the back casing 3 of low temperature by the 2nd heating panel 40 and flange part 45b direct heat, the temperature that suppresses power MOSFET 38 raises.Again, make fan-shaped in fact flange part 45b roomy area contact back casing 3 end face and the 1st heating panel the 39, the 2nd heating panel the 40, the 1st and the 2nd circuit board 44 and 45A clamped and fixing, thereby obtain higher vibration resistance.

According to this execution mode 4, the 1st heating panel 139 is become 2 layers with the 2nd heating panel 140 in the axial arrangement of axle 5, so the 1st and the 2nd heating panel 139,140 can be expanded to the radial dimension of qualification.Therefore, can enlarge the surface area and the volume of the 1st and the 2nd heating panel 139,140 that is used for the big power MOSFET of cooling controller 130 caloric values 37,38, so effective cooling power MOSFET37,38 and control device 130 is maximized.Therefore, can in limited radial dimension, guarantee the optimum surface area and the volume of the 1st and the 2nd heating panel 139,140, and seek the miniaturization of control device 130.
Between face side, the 1st heating panel 139 and the 2nd heating panel 140 of the 1st heating panel 139, and then between the wall of the 2nd heating panel 140 and back casing 3, constitute the wind path of cooling air again.Therefore, cooling air is moving along two surface currents of the 1st heating panel 139 and the 2nd heating panel 140, and institute is so that the raising of cooling property.Owing to avoid foreign matter or conductivity attachment to be detained, can strengthen air quantity, and can reduce wind noise again.
And the 1st heating panel 139 and the 2nd heating panel 140 radially stagger axle 5, and therefore the cooling air with axial flow is directed to the 2nd heating panel 140 and not hindered by the 1st heating panel 139.Therefore, cooling air arrives the 2nd heating panel 140 and does not warm because of the 1st heating panel 139 is cooled off, so the cooling air that will not warm is directed to the 1st heating panel 139 and the 2nd heating panel 140, makes the raising of cooling property.
Again, owing to offer ventilation hole 151a, 151b, make in its table that connects the 1st and the 2nd heating panel 139,140, therefore the cooling air toward axial and Radial Flow circulates in ventilation hole 151a, 151b.Therefore, windage is little, air quantity is strengthened, and can reduce wind noise.
And lead-out terminal bolt 148 reaches axial foreign side from the rear end of motor generator for vehicle 101, so under the rear view of vehicle situation of having living space, it is convenient to install with the connecting wiring of storage battery 23 exterior parts such as grade.
Again, because lead-out terminal bolt 148 is installed in the 1st heating panel 139, therefore the 1st heating panel 139 needs to install the flange 139b of lead-out terminal bolt 148 usefulness, and the area of dissipation of the 1st heating panel 139 is reduced.Yet,, therefore can suppress the cooling deterioration that area of dissipation reduces to bring because the upstream that the axial flow direction of 139 pairs of cooling airs of the 1st heating panel of lead-out terminal bolt 148 is in the 2nd heating panel 140 is installed.
Here, preferably make the radial width of base portion 139a of the 1st heating panel 139 greater than the radial width of the base portion of the 2nd heating panel 140.In the case, it is big that the area of dissipation of the 1st heating panel 139 becomes, so prevent to install the cooling deterioration of the 1st heating panel 139 that lead-out terminal bolt 148 causes.Therefore, the cooling effectiveness of the 1st heating panel 139 equals the cooling effectiveness of the 2nd heating panel 140 in fact, can with the 1st with the 2nd heating panel 139,140 on the power MOSFET 37,38 installed be cooled to identical in fact temperature.Because it is the rigidity of the 1st heating panel 139 is big, favourable on intensity again to external force from external connection line.Therefore, even the stress of external force when storage battery 32 exterior parts such as grade are installed to lead-out terminal bolt 148 or vibration external force also can prevent the state of affairs of the 1st heating panel 139 fractures in the 1st heating panel 139.
And, owing to, clamp and be fixed on with being integrated the end face of back casing 3 by construction bolt 147, so obtain high vibration resistance with the 1st and the 2nd heating panel 139,140 and the 1st and the 2nd circuit board 144,145 state after with assembling.
The 2nd heating panel 140 is fixed on the end face of back casing 3 by the flange part 145b of the 2nd circuit board 145 again.Therefore, the heat of power MOSFET 38 arrives back casing 3 by the 2nd heating panel 140 and flange part 45b heat conduction, so power MOSFET 38 is effectively cooled off.
And, the surface of base portion 145a is to separate the position of the installed surface of fin 141～143 with one side with the 1st to the 3rd, expose on the surface in the zone of the base portion 145a corresponding another of embedded conductor 150a～150f is distolateral with the source terminal 38S of power MOSFET 38 and gate terminal 38G, and the face that exposes that the source terminal 38S and the gate terminal 38G of power MOSFET 38 is welded on corresponding embedded conductor 50a～50f.Therefore, source terminal 38S and gate terminal 38G and embedded conductor 150a～150f that can direct and simple and easy connection power MOSFET 38, and can miniaturization.
Again, embed embedded conductor 150a, 150c, the 150e that molding is electrically connected with the source terminal 38S of power MOSFET 38 at the 2nd circuit board 145, it is exposed at the back side of flange part 145b, and utilize the fastening force of construction bolt 147 to make it contact the end face of back casing 3.Therefore, do not need to connect the connection electrode member of embedded conductor 150a, 150c, 150e and back casing 3, reduce the number of components of this part, can reduce weight and cost, and simplify the connection operation.Also back casing 3 is used as the ground of motor generator for vehicle 101,, is reduced number of components, can reduce weight and cost so do not need to have the electrode member of negative potential.Again owing to the source terminal 38S of power MOSFET 38 is connected to back casing 3 by embedded conductor 150a, 150c, 150e, the hot direct heat of power MOSFET 38 is transmitted to the back casing 3 of low temperature, stay out of air, thereby the temperature that suppresses power MOSFET 38 raises.
Figure 28 is the longitudinal section of main assembly that the motor generator for vehicle of embodiment of the present invention 5 is shown, Figure 29 is the rear end view drawing of seeing the state that unloads cover cap from the rear of the motor generator for vehicle of embodiment of the present invention 5, Figure 30 is the vertical view of control device that the motor generator for vehicle of embodiment of the present invention 5 is shown, Figure 31 be the D-D of Figure 29 to looking cutaway view, Figure 32 is that the E-E of Figure 29 is to looking cutaway view.
Among Figure 28 to Figure 32, the cross section that the 2nd circuit board 145A forms base portion 145a and flange part 145b composition had the fan-shaped in fact of L shape at control device 130A.And, the 1st to the 3rd separate heating panel 141～143 and line up fan-shaped in fact what constitute the 2nd heating panel 140, and show out with the 2nd circuit board 145A surface and the internal perisporium that the ground mould-forming gets separately that be integrated.So, line up surface that the 1st to the 3rd of fan-shaped in fact separates heating panel 141～143 for the surperficial same position of the base portion 145a of the 2nd circuit board 145A, cover the 1st to the 3rd back side of separating heating panel 141～143 by flange part 145b.
Again, embed 6 embedded conductor 150a～150f of molding at the 2nd circuit board 145A, but be partially submerged into conductor 150a, 150c, 150e and near the connection protuberance 154 of the end face that is erected to be arranged at back casing 3, reach radial outside, to replace exposing the back side at flange part 145d from base portion 145a.And, the extension 152 of embedded conductor 150a, 150c, 150e is clamped and is fixed on the connection protuberance 154 of back casing 3 respectively by screw 153.
Other forms identical with above-mentioned execution mode 4.
Among this motor generator for vehicle 101A, the 2nd circuit board 145A being separated heating panel 141～143 on the end face of back casing 3 with the 1st to the 3rd, is that center configuration becomes fan-shaped in fact with the axle center of back casing 3.And it is relative with the flange part 145b of the 2nd circuit board 145A that the 1st circuit board 144 is configured to separate heating panel 141～143 across the 1st to the 3rd.Also dispose the 1st heating panel 139, each flange part 139b is stated from the flange part 144b of the 1st circuit board 144, and make the interior all side of base portion 139a near the base portion 144a of the 1st circuit board 144.
And, the flange part 145b of the circumferential flange part 144b except that circumferential another 3 places distolateral of the flange part 139b except that circumferential another distolateral 3 places of the 1st heating panel 139, the 1st circuit board 144, the 1st to the 3rd separation heating panel 141～143 circumferential one distolateral and the 2nd circuit board 145A separately respectively at axial overlap, and is fixedly clamped at back casing 3 by construction bolt 147.Lead-out terminal bolt 148 also is installed, is made it connect circumferential another distolateral flange part 139b of the 1st heating panel 139, reach the axial outside from cover cap 118 from rear side.And, the extension 152 of embedded conductor 150a, 150c, 150e is clamped and is fixed on the connection protuberance 154 of back casing 3 by screw 153.Binding post 146 is contained between the head and flange part 139b of lead-out terminal bolt 148 again.The flange part 144b of the 1st circuit board 144 is contained in lead-out terminal bolt 148 separates between the heating panel 143, and both are electric insulating state with the 3rd.
Like this among the motor generator for vehicle 101A of Gou Chenging, circumferential whole zone at the 2nd circuit board 145A, flange part 145b is close to the end face of back casing 3, except that cooling airflow Fa～Fc shown in Figure 20, also utilize flange part 145b that back casing 3 is conducted heat, make control device 130A cooling by the 2nd circuit board 145A.
In this execution mode 5, identical with above-mentioned execution mode 4, owing to become 2 layer and radially mutually stagger with the 2nd heating panel 139,140 in axial arrangement with the 1st, so windage reduces, and it is big that the air quantity of cooling air becomes.So, the heat of power MOSFET 38 from the flange part 145b heat conduction of the 2nd heating panel 140 by the 2nd circuit board 145A to back casing 3, by the exhausting window joint-cutting 3a air cooling that is cooled.Therefore, the flow of cooling air increases, and the amount of heat transfer to back casing 3 is increased, so the reinforcement that both multiply each other increases the heat exchange amount from back casing 3, the temperature that suppresses control device 130A raises.
Again,, therefore obtain high vibration resistance, and cut down number of components, be convenient to install because the 2nd heating panel 140 (the 1st to the 3rd separates heating panel 141～143) must be integrated with the 2nd circuit board 145A mould-forming.
And, the flange part 145b of circuit board 145A is formed fan-shaped in fact.Therefore, the heat of power MOSFET 38 is delivered to the back casing 3 of low temperature by the 2nd heating panel 140 and flange part 145b direct heat, the temperature that suppresses power MOSFET 38 raises.Again, make fan-shaped in fact flange part 145b roomy area contact back casing 3 end face and the 1st heating panel the 139, the 2nd heating panel the 140, the 1st and the 2nd circuit board 144 and 145A clamped and fixing, thereby obtain higher vibration resistance.
Moreover, in the prior art, the drain electrode of underarm and source electrode () non-same plane, need on the space to connect the connecting elements of usefulness, cause maximizing.Yet in this execution mode 5, the extension 152 of embedded conductor 150a, 150c, 150e reaches the outside from base portion 145a near the connection protuberance 154 of back casing 3 and with identical in fact height.Therefore, the length of embedded conductor 150a, 150c, 150e is short, extension 152 be connected the easy to connect of protuberance 154.That is,, do not need the big connecting elements that needs in the prior art, can seek miniaturization according to this execution mode 5.
Figure 33 is the longitudinal section of main assembly that the motor generator for vehicle of embodiment of the present invention 6 is shown, Figure 34 is a rear end view drawing of seeing the motor generator for vehicle of embodiment of the present invention 6 from the rear, Figure 35 is the rear end view drawing of seeing the state that unloads cover cap from the rear of the motor generator for vehicle of embodiment of the present invention 6, Figure 36 is the vertical view of control device that the motor generator for vehicle of embodiment of the present invention 6 is shown, Figure 37 be the F-F of Figure 35 to looking cutaway view, Figure 38 is that the G-G of Figure 35 is to looking cutaway view.
Among Figure 33 to Figure 38, on control device 130B, the shape that the 1st heating panel 139A forms has to be equal to separates heating panel 141～143 with the 1st to the 3rd and lines up the base portion 139a of the fan-shaped in fact of the 2nd heating panel 146 of fan-shaped in fact and be arranged to from this 4 flange part 139c that protrudes toward the rear side of base portion 139a of the part of branch base portion 139a such as circumferential two ends of base portion 139a and circumferential 3.That is the thickness of the part of the flange part 139c of rear side thickening base portion 139a.And, the flange part 144b that the shape that the 1st circuit board 144A forms has along the base portion 144a of the fan-shaped in fact (C shape) of the base portion 139a institute periphery of the 1st heating panel 139A and is arranged to extend toward interior all sides from the back side of this base portion 144a of 4 of part of branch base portion 144a such as circumferential two ends of base portion 144a and circumferential 3.
Among this 1st circuit board 144A, embed 6 embedded conductor 149a～149f of molding, but the part of embedded conductor 149a～149f is exposed the back side of flange part 144b at 3 places distolateral except that circumferential another at the 1st circuit board 144.Be adjacent to respectively and separate heating panel the 141, the 3rd the 1st and separate heating panel 143 and separates heating panel 142 with the 1st and also be electrically connected by the fastening force of construction bolt 147 the face that exposes these embedded conductors 149a, 149c, 149e.
Again, the side wall surface with suction hole 118a only is formed on cover cap 118A is not formed on its end face.And, at 1st heating panel 139A deviate from back cover side, 1st heating panel 139A and 2nd heating panel 140 between and separately the radial outside on the back cover side of 2nd heating panel 140 forming on the cover cap 118A suction hole 118a.
Other forms identical with above-mentioned execution mode 4.
Among this motor generator for vehicle 101B, with the 2nd circuit board 145 on the end face of back casing 3, axle center with back casing 3 is that center configuration becomes fan-shaped in fact, and dispose the 1st to the 3rd and separate heating panel 141～143, its two ends separately are stated from the flange part 145b, near interior all sides of base portion 145a, be the center with the axle center of back casing 3, line up fan-shaped in fact.Again, it is relative with the flange part 145b of the 2nd circuit board 145 the 1st circuit board 144A to be configured to separate heating panel 141～143 across the 1st to the 3rd.Also dispose the 1st heating panel 139A, each flange part 139b is stated from the flange part 144b of the 1st circuit board 144A, and make the interior all side of base portion 139a near the base portion 144a of the 1st circuit board 144A.
And, the circumferential flange part 145b except that circumferential another 3 places distolateral of the circumferential flange part 144b except that circumferential another distolateral 3 places except that circumferential another distolateral flange part 139c, the 1st circuit board 144A of the 1st heating panel 139A, the 1st to the 3rd separation heating panel 141～143 circumferential one distolateral and the 2nd circuit board 145 separately is fixedly clamped at back casing 3 by construction bolt 147 respectively.Lead-out terminal bolt 148 also is installed, is made it connect circumferential another distolateral flange part 139b of the 1st heating panel 139 from rear side.Binding post 146 is contained between the head and flange part 139b of lead-out terminal bolt 148 again.The flange part 144b of the 1st circuit board 144A is contained in lead-out terminal bolt 148 separates between the heating panel 143, and both are electric insulating state with the 3rd.
Thus, the 1st to the 3rd separates heating panel 141～143 except that axial two ends separately, deviates from the share of thickness of flange part 145b of wall the 2nd circuit board 145 of back casing 3, to constitute the cooling air wind path.And the 1st heating panel 139A separates heating panel 141～143 gross thickness toward thickness with the thickness of the flange part 144b of the 1st circuit board 144A of the flange part 139b of the axially-spaced at least the 1 heating panel 139A of axle 5 with the 1st to the 3rd, with formation cooling air wind path.Also the base portion 139a of the 1st heating panel 139A is separated the axially overlapped of 140 pairs of axles 5 of the 2nd heating panel that heating panel 141～143 forms with the 1st to the 3rd.
In this execution mode 6, become 2 layers with the 2nd heating panel 139A, 140 toward axial arrangement, therefore obtain the effect identical with above-mentioned execution mode 2 with the 1st.
And, dispose to such an extent that radial position is identical with the 2nd heating panel 139A, 140 with the 1st, promptly to axial overlap.Only the side wall surface at cover cap 118A forms suction hole 118a, therefore from suction hole 118a flow in the cover cap 118A cooling air respectively the 1st heating panel 139A deviate between busbar side, the 1st heating panel 139A and the 2nd heating panel 140 and flow toward radially inner side in the back cover side of the 2nd heating panel 140, in suction hole 3b inflow back casing 3.Therefore, do not hinder the Radial Flow of cooling air, can strengthen the 1st and the 2nd heating panel 139A, 140 area of dissipation.Again, with the cooling air of the same temperature of atmosphere from radial inflow the 1st and the 2nd heating panel 139A, 140, so obtain high cooling property.Because it is equal in fact to supply with the temperature of the 1st and the 2nd heating panel 139A, 140 cooling air, can will be contained in the 1st and be cooled to identical in fact temperature with the 2nd heating panel 139A, 140 power MOSFET 37,38.
Again because the 1st and the 2nd heating panel 139A, 140 couples are axial overlapped, can guarantee around the axle 5 cooling air flow along the 1st and the 2nd heating panel 139A, 140 and be passed to connecting shaft 5 around the wind path of the back suction hole 3b that also flows to.Therefore, windage is little, so air quantity is big, makes the raising of cooling property.
Again, under the situation of high-temperature portion such as the rear of the motor generator for vehicle configuration exhaust pipe of engine, or the rear of motor generator for vehicle installs under the situation of big output stroma, and cooling air is obstructed to the inflow in the motor generator for vehicle, the deterioration of cooling property.Yet, this motor generator for vehicle 101B is used for the occasion that big output stroma is installed at the rear of the occasion of high-temperature portion such as the rear configuration exhaust pipe of engine of motor generator for vehicle 101B or motor generator for vehicle 101B, then make the exhaust pipe of engine or output stroma without hindrance, can realize good cooling the Radial Flow of cooling air.
Moreover, in the above-mentioned execution mode 4～6, explain to constitute be connected in parallel the respectively mode of 4 power MOSFETs 37,38 of upper arm 131,133,135 and underarm 132,134,136, but the quantity of the power MOSFET 37,38 that is connected in parallel is not limited to 4, can suitably set according to the heap(ed) capacity of the output capacity of desired motor generator for vehicle, semiconductor element and allowable temperature etc., the quantity of the power MOSFET 37,38 that for example is connected in parallel can be 2 or 3, and 1 power MOSFET 37,38 also can.
In the above-mentioned execution mode 4～6, lead-out terminal bolt 148 is mounted to toward axially stretching out, but also the lead-out terminal bolt can be mounted to toward extending radially out again.
