以上のような本発明の実施形態１による制御装置一体型回転電機１は、駆動補助としての電動機の機能と、発電のための発電機の機能とを備えている。 The above-described controller-integrated rotating electrical machine 1 according to the first embodiment of the present invention has a function of an electric motor as driving assistance and a function of a generator for power generation.
まず、駆動の補助として機能する際には、外部バッテリーからパワー回路部１８に供給された直流電力が、パワー回路部１８のスイッチング素子のＯＮ/ＯＦ制御によって３相交流電流に変換されて固定子巻線１１に供給される。また、外部バッテリーから供給される直流電力が、界磁回路部で調整されて回転子巻線６に供給されることで、回転機巻線６の周囲に回転磁界が生じ、回転子軸４が回転される。回転子軸４の回転はプーリー１３から伝動ベルト（図示せず）を介してエンジン（図示せず）に伝達される。制御回路部１９は、外部機器および回転位置検出センサ１４からの情報に基づいて、上記のパワー回路部１８と界磁回路部とを制御する。 First, when functioning as driving assistance, direct current power supplied from an external battery to the power circuit unit 18 is converted into a three-phase alternating current by ON / OF control of a switching element of the power circuit unit 18 to be fixed to the stator. It is supplied to the winding 11. Further, the DC power supplied from the external battery is adjusted by the field circuit unit and supplied to the rotor winding 6, whereby a rotating magnetic field is generated around the rotating machine winding 6, and the rotor shaft 4 is It is rotated. The rotation of the rotor shaft 4 is transmitted from the pulley 13 to an engine (not shown) via a transmission belt (not shown). The control circuit unit 19 controls the power circuit unit 18 and the field circuit unit based on information from the external device and the rotational position detection sensor 14.
また、発電機として機能する際には、エンジンの回転力が伝動ベルトおよびプーリー１３を介して回転子軸４に伝達される。これにより、回転子５が回転して固定子巻線１１に３相交流電力が励起される。制御回路部１９はパワー回路部１８のスイッチング素子のＯＮ/ＯＦを制御し、固定子巻線１１に励起された３相交流電力を直流電力に変換する。変換された直流電力が外部バッテリーに供給され、バッテリーが充電される。 When functioning as a generator, the rotational force of the engine is transmitted to the rotor shaft 4 via the transmission belt and the pulley 13. As a result, the rotor 5 rotates and three-phase AC power is excited in the stator winding 11. The control circuit unit 19 controls ON / OF of the switching element of the power circuit unit 18 and converts the three-phase AC power excited by the stator winding 11 into DC power. The converted DC power is supplied to the external battery, and the battery is charged.
次に本実施の形態の外部接続コネクタ２４の固定構造を説明する。
図２は外部接続コネクタ２４の周辺のみを拡大して表示した断面図であり、外部接続コネクタ２４の固定構造を示している。外部接続コネクタ２４はその嵌合部２４ｂがＰＰＳ等の樹脂で形成され、外部接続端子２４ａがインサートモールド成形されている。外部接続コネクタ２４は、制御基板２３のヒートシンク２０側とは反対の側の面上に、外部接続端子２４ａを制御基板２３のスルーホール２８に挿入して実装され、外部接続端子２４ａと制御基板２３の基板電極２９とがはんだ３０によって接合されている。このようにして実装された外部接続コネクタ２４の筒状の嵌合部２４ｂは、ヒートシンク２０側とは逆方向に延在するように設けられることになる。また、嵌合部２４ｂの少なくとも一部が制御基板２３ととともに封止樹脂２６によって封止されている。外部接続コネクタ２４が封止樹脂２６で封止固定されているため、外部機器の接続コネクタ（図示省略）を外部接続コネクタ２４に取付ける際の、外部接続コネクタ２４の破損を防止することができる。また、使用中の破損も防止することができる。なお、外部接続コネクタ２４は、制御基板２３の回転電機径方向のほぼ中央部に配設されている。
Next, the fixing structure of the external connection connector 24 of the present embodiment will be described.
FIG. 2 is an enlarged cross-sectional view showing only the periphery of the external connection connector 24 and shows a fixing structure of the external connection connector 24. The fitting portion 24b of the external connection connector 24 is formed of a resin such as PPS, and the external connection terminal 24a is insert-molded. The external connection connector 24 is mounted on the surface of the control board 23 opposite to the heat sink 20 side by inserting the external connection terminals 24a into the through holes 28 of the control board 23, and the external connection terminals 24a and the control board 23 are mounted. The substrate electrode 29 is joined by solder 30. The cylindrical fitting portion 24b of the external connector 24 thus mounted is provided so as to extend in the direction opposite to the heat sink 20 side. Further, at least a part of the fitting portion 24 b is sealed together with the control substrate 23 by the sealing resin 26. Since the external connection connector 24 is sealed and fixed with the sealing resin 26, the external connection connector 24 can be prevented from being damaged when a connection connector (not shown) of an external device is attached to the external connection connector 24. Further, damage during use can be prevented. The external connection connector 24 is disposed at a substantially central portion of the control board 23 in the radial direction of the rotating electrical machine.
このように、本実施の形態の固定構造を採用すれば、外部接続コネクタ２４を回転電機の径内に収めることができ、回転電機の径方向のスペースが僅かしか確保できない車種においても、制御装置一体型回転電機を取付けることが可能となる。 As described above, by adopting the fixing structure of the present embodiment, the external connection connector 24 can be accommodated within the diameter of the rotating electrical machine, and the control device can be used even in a vehicle type in which only a small space in the radial direction of the rotating electrical machine can be secured. An integrated rotary electric machine can be attached.
図３は外部接続コネクタ２４の周辺のみを拡大して表示した断面図であり、外部接続コネクタ２４の別の固定構造を示している。図のように外部接続コネクタ２４の嵌合部２４ｂの一部に、嵌合部２４ｂの周方向に嵌合部２４ｂより突出させた箇所すなわちフランジ部２４ｃを設けることで、封止樹脂２６による固定面積が増大し、図２の例より外部接続コネクタ２４の固定強度が向上し、外部接続コネクタ２４の破損をより生じにくくできる効果が得られる。なお、フランジ部２４ｃの設置位置より低背な実装部品３１はフランジ部２４ｃの下方にも実装できるため、実装密度の低下は防止できる。 FIG. 3 is an enlarged cross-sectional view showing only the periphery of the external connection connector 24 and shows another fixing structure of the external connection connector 24. As shown in the figure, a portion that protrudes from the fitting portion 24b in the circumferential direction of the fitting portion 24b, that is, a flange portion 24c, is provided on a part of the fitting portion 24b of the external connection connector 24, thereby fixing with the sealing resin 26. The area is increased, the fixing strength of the external connection connector 24 is improved as compared with the example of FIG. 2, and the effect that the external connection connector 24 is less likely to be damaged can be obtained. In addition, since the mounting component 31 that is lower than the installation position of the flange portion 24c can be mounted below the flange portion 24c, a reduction in mounting density can be prevented.
図４は本実施の形態の外部接続コネクタ２４の別の構造を示す斜視図である。図２や図３に示した固定構造では、まず外部接続端子２４ａを制御基板２３にはんだ付けした後で、パワー回路部１８の制御信号配線２２ｂおよび界磁回路部の制御信号配線と制御基板２３とがはんだ付けされることになる。制御信号配線は本数が多く、通常は噴流はんだ付け法を用いて一括ではんだ付けされるが、外部接続コネクタ２４等の高背な部品があると、噴流はんだ付け法が使用できずに生産性が低下する。これに対し、図４に示す外部接続コネクタ２４では、嵌合部２４ｂの少なくとも一部に開口部３２を設け、制御基板２３に外部接続コネクタ２４を実装した時に、外部接続端子２４ａと基板電極２９とのはんだ付け部が露出するように構成している。このような構成とすることで、先にパワー回路部１８の制御信号配線２２ｂおよび界磁回路部の制御信号配線と制御基板２３とを噴流はんだ付け法で一括接続した後で、外部接続端子２４ａと基板電極２９とをはんだ付けロボットやレーザはんだ付け法を用いてはんだ付けすることが可能となる。外部接続端子２４ａの本数は制御信号配線の総数より少ないため、本構造によって生産性の低下を抑制する効果が得られる。 FIG. 4 is a perspective view showing another structure of the external connection connector 24 of the present embodiment. In the fixing structure shown in FIGS. 2 and 3, the external connection terminal 24 a is first soldered to the control board 23, and then the control signal wiring 22 b of the power circuit section 18 and the control signal wiring of the field circuit section and the control board 23. And will be soldered. There are many control signal wires, and they are usually soldered together using the jet soldering method. However, if there are high-profile parts such as the external connector 24, the jet soldering method cannot be used and the productivity is high. Decreases. On the other hand, in the external connection connector 24 shown in FIG. 4, when the opening 32 is provided in at least a part of the fitting portion 24 b and the external connection connector 24 is mounted on the control board 23, the external connection terminal 24 a and the board electrode 29 are provided. The soldering part is exposed. With such a configuration, after the control signal wiring 22b of the power circuit unit 18 and the control signal wiring of the field circuit unit and the control board 23 are collectively connected by the jet soldering method, the external connection terminal 24a And the substrate electrode 29 can be soldered using a soldering robot or a laser soldering method. Since the number of external connection terminals 24a is smaller than the total number of control signal wirings, the effect of suppressing the decrease in productivity can be obtained by this structure.

Other structures are the same as those in the first embodiment. The external connector 24 has a portion protruding from the fitting portion 24b in the circumferential direction of the fitting portion 24b, that is, a flange portion 24c, in a part of the fitting portion 24b, and the flange portion 24c and the case 25 are fixed. Yes. In the present embodiment, the nut 33 is insert-molded in the case 25, and the metal ring 35 insert-molded in the flange portion 24c with the bolt 34 and the nut 33 of the case 25 are fastened and fixed. Thus, by fixing the external connection connector 24 to the case 25 as well, the fixing strength is further increased and the effect of preventing the external connection connector 24 from being damaged is improved.
また、図６は本実施の形態の外部接続コネクタ２４の別の固定構造の例を示した断面図である。この例でも、外部接続コネクタ２４は嵌合部２４ｂの一部にフランジ部２４ｃを有し、フランジ部２４ｃとケース２５とが固定されている。本例では、ボルト３４でフランジ部２４ｃにインサート成形した金属リング３５とヒートシンク２０とを締結することで、外部接続コネクタ２４をケース２５に固定した。なお、ケース２５のボルト３４が挿入される孔には、補強用の金属リング３５をインサート成形した。この例でも、外部接続コネクタ２４の破損を防止する効果が向上できる。 FIG. 6 is a sectional view showing an example of another fixing structure of the external connection connector 24 of the present embodiment. Also in this example, the external connection connector 24 has a flange portion 24c in a part of the fitting portion 24b, and the flange portion 24c and the case 25 are fixed. In this example, the external connection connector 24 is fixed to the case 25 by fastening the metal ring 35 insert-molded to the flange portion 24 c with the bolt 34 and the heat sink 20. A reinforcing metal ring 35 was insert-molded into the hole of the case 25 into which the bolt 34 is inserted. Also in this example, the effect of preventing the external connection connector 24 from being damaged can be improved.
