The control unit 30 incorporates various electronic elements (not shown) in a hollow rectangular parallelepiped control unit case 31. The control unit 30 rotates the rotor 13 and the crankshaft 52 by controlling energization of the coil 11 at a predetermined timing when the engine 50 is started. In contrast to this, after the engine 50 is started, the control unit 30 charges the generated electric power accompanying the rotation of the rotor 13 to an auxiliary device such as a battery (not shown) or directly uses it for a lighting device such as a light.
回転電機ユニット1は、3相の位置検出センサ47(図4参照)を備える。位置検出センサ47は、ステータ12のあらかじめ定められた位置に配置され、ロータ13の回転位置を検出する。位置検出センサ47によって検出されたロータ13の回転位置信号は、制御部30に取り込まれ、この制御部30によってエンジン50の点火タイミングを制御したり、コイル11の転流タイミングを制御したりする。
The rotating electrical machine unit 1 includes a three-phase position detection sensor 47 (see FIG. 4). The position detection sensor 47 is disposed at a predetermined position of the stator 12 and detects the rotational position of the rotor 13.

Here, the control unit 30 is disposed in the cooling air passage A of the engine 50, and the cooling air flowing through the cooling air passage A of the engine 50 is positively blown against the control unit 30. Further, the control unit 30 is arranged on the side of the cylinder 53 of the engine 50, and it is easy to secure a space for arranging the control unit 30. Furthermore, since the control unit 30 is separated from the engine 50 (cylinder 53) and forms a space S between the control unit 30 and the engine 50 (cylinder 53), the control unit 30 can be provided with a sufficient space, and the space The controller 30 does not directly receive the heat generation component of the engine 50 due to S.

The
ベース部40には、ベース部通気孔43が形成されている。ベース部通気孔43は、例えば丸孔であって、ベース部40における断熱材60側の表面から断熱材60と反対側の裏面まで、ベース部40の厚さ方向で貫通形成されている。ベース部通気孔43は、平面視でモータ部10と制御部30との間に配置され、ベース部40の裏面で空間Sに開口する。
The base portion 40 has a base portion vent hole 43 formed therein. The base portion vent hole 43 is, for example, a round hole, and is formed through the base portion 40 in the thickness direction from the surface on the heat insulating material 60 side to the back surface opposite to the heat insulating material 60. The base portion vent hole 43 is disposed between the motor unit 10 and the control unit 30 in a plan view and opens into the space S on the back surface of the base unit 40.
また、熱抵抗体としての断熱材60には、断熱材通気孔61が形成されている。断熱材通気孔61は、例えば丸孔であって、断熱材60におけるベース部40と反対側の表面からベース部40側の裏面まで、断熱材60の厚さ方向で貫通形成されている。断熱材通気孔61は、平面視でベース部通気孔43と重なるように配置され、ベース部通気孔43と連通するように設けられる。

As shown in FIG. 5, the rotating electrical machine unit 2 includes a control unit 70 in which a control unit case 71 is integrally formed with a base unit 72. The control unit case 71 is formed of, for example, an aluminum alloy as in the case of the base unit 72 and has a single configuration including the base unit 72.

FIG. 6 is a plan view of the rotatingelectrical machine unit 3 according to the third embodiment of the present invention viewed from the axial direction. FIG. 7 is an arrow view corresponding to FIG. 3 in FIG.
The third embodiment is different from the second embodiment in that thebase portion 80 is provided with a through hole 81 that is a vertical hole constituting the heat resistance structure, and the other is substantially the same.

図6に示すように、回転電機ユニット3は、ベース部80の貫通孔81をモータ部10から制御部30に向く方向に対して直交するように複数個配置している。ベース部80は、モータ部10及び制御部30を一体に支持する。

The base unit 80 integrally supports the motor unit 10 and the control unit 30.
図7に示すように、貫通孔81は、例えば丸孔であって、ベース部80の上面から下面に貫通形成されている。そのため、貫通孔81によって、モータ部10から制御部30に至る熱伝達路が小さくなることにより、モータ部10からの発熱成分が制御部30に伝わりにくくなる。また、貫通孔81を通じて冷却風が流通されることにより、貫通孔81が形成されている箇所が積極的に冷却される。

図12に示すように、上板121は、ベース部120の上面に予め定められた高さ寸法を有して縦断面視L字形状に突出形成されており、モータ部10から制御部30に向く方向に対して直交するように複数個配置している。このL字形状は、貫通孔123に対して冷却風を誘導する(図12における矢印Y1参照)ように折曲されている。
As shown in FIG. 12, the upper plate 121 has a predetermined height dimension on the upper surface of the base portion 120 and is formed to project in an L shape in a longitudinal sectional view. A plurality are arranged so as to be orthogonal to the direction in which they face. The L shape is bent so as to induce cooling air to the through hole 123 (see arrow Y1 in FIG. 12).

制御部側ベース部152は、エンジンカバー54に延設されているブラケット153に固定されている。ブラケット153は、冷却風通路Aを流通する冷却風の流れを阻害しないように形成されている。
そして、モータ部10から引き出された配線154が、制御部30に有するコネクタ155を通じて制御部30内に電気的に接続されている。なお、配線154は、ステータ12に巻回されているコイル11がそのまま引き出されたものであってもよいし、位置検出センサ47(図4参照)に接続される配線47aがそのまま引き出されたものであってもよい。 The control unitside base unit 152 is fixed to a bracket 153 that extends to the engine cover 54.
