Description
モータやオルタネータ等の回転電機のフレームやハウジング等といった回転構造体の外形器は、回転機能を実現するために、一般的に円形を基本に設計されている。そのため、機電一体構造として、コンパクトな構造を模索した場合、インバータ回路等の電気電子回路部も、体積占有構造としては、円筒形の内部空間に収まるように設計することが望ましい。すなわち、各機能部品は、それ自身が円筒形に近いほど効率よく許容空間内に収容できることとなる。
そのため、インバータモジュール自身の搭載性・放熱性能、およびモジュールの形状にまつわり考慮されるべき基板等の周囲の搭載物の搭載性を改善することができる。
図1(a)、(b)は、この発明の実施の形態1に係るモールドモジュールを示す構成図である。図1(a)、(b)において、モールドモジュール内には、大電流の通電の通電制御をおこなうために必要な半導体スイッチング素子101(MOSFET)、電流検出用のシャント抵抗器102およびノイズ対策用のコンデンサ103を、回路機能の構成をすべく内蔵している。
そのため、インバータモジュール自身の搭載性・放熱性能、およびモジュールの形状にまつわり考慮されるべき基板等の周囲の搭載物の搭載性を改善することができる。
モールドモジュールの曲線形状または多角形形状にモールド成形されたモールド外周部からの、電気的接続に必要な端子の引き出しについては、機器への実装効率を改善するために、端子の曲げ位置を、曲線または多角形の外周形状に沿うように構成することが効果的である。
モールドモジュールの配置面において、他部品も含めた実装効率を上げるために、モールドモジュールの電極引き出しに関与しない側面に、窪みをつけるようにしてもよい。以下、図7を参照しながら、このような構成を実現する方法について説明する。図7は、この発明の実施の形態3に係るモールドモジュールの外形形状を示す構成図である。
上記実施の形態1では、モールドモジュールとヒートシンクとの間の放熱と絶縁を行うために、放熱シートおよびグリスを挟み込み、組み立てることを提案したが、放熱シートは、リードフレームと密着させて樹脂で一体に成形してもよい。
