Abstract
Description
ハウジング14は、伝熱性を有する材料(例えばアルミニウム等の金属)で形成されている。ハウジング14は、車両のボディに接地されている。
回転軸17は、ハウジング14に対して回転可能な状態で支持されている。回転軸17は、その軸線方向が板状の底壁部15aの厚さ方向(換言すれば筒状の側壁部15bの軸線方向)と一致する状態で配置されている。回転軸17と圧縮部18とは連結されている。
インバータ装置30は、電動モータ19を駆動するためのものである。インバータ装置30は、インバータ回路31(図2参照)と、ノイズ低減部32(図2参照)を備えている。インバータ回路31は、直流電力を交流電力に変換するためのものである。ノイズ低減部32は、インバータ回路31の入力側に設けられるとともにインバータ回路31に入力される前の直流電力に含まれるコモンモードノイズ及びノーマルモードノイズを低減させるためのものである。
図2に示すように、電動モータ19のコイル23は、例えばu相コイル23u、v相コイル23v及びw相コイル23wを有する三相構造となっている。各コイル23u〜23wは例えばY結線されている。
Xコンデンサ35は、コモンモードチョークコイル34に対して後段(インバータ回路31側)に設けられており、両接続ラインEL1,EL2に電気的に接続されている。コモンモードチョークコイル34とXコンデンサ35とによってLC共振回路が構成されている。即ち、本実施形態のローパスフィルタ回路36は、コモンモードチョークコイル34を含むLC共振回路である。
なお、図面において、3軸直交座標を規定しており、図1の回転軸17の軸線方向をZ方向とし、Z方向に直交する方向をX,Y方向としている。
金属膜70は、銅箔よりなる。即ち、環状の導電体としての金属膜70は膜形状である。金属膜70の厚さは、10μm〜100μmである。例えば金属膜70の厚さは35μmである。薄くするのは、電流(誘導電流)が流れたときに抵抗を大きくして熱に変えるためである。反面、薄くすると強度を保ちにくく形状を保持しにくい。
樹脂層80により、金属膜70の強度保持、高剛性とともに絶縁性確保が図られている。樹脂層80は、ポリイミドよりなり、薄い金属膜70に対し強度を保ち形状を保持することができる。樹脂層80の厚さは、例えば数10μmである。なぜなら、巻線60,61と金属膜70とは、より接近しているのが望ましく、巻線60,61により発生する磁界を金属膜70で受けて誘導電流が流れるからであり、接近していると誘導電流が流れやすい。
図3(b)、図5に示すように、金属膜70における吸入ハウジング15の底壁部15aとの対向面には放熱グリス90が配置されている。これにより、金属膜70は、吸入ハウジング15ひいてはハウジング14に熱的に結合している。
図6に示すように、第1の巻線60及び第2の巻線61の通電により電流i1,i2が流れる。これに伴いコア50に磁束φ1,φ2が発生するとともに漏れ磁束φ3,φ4が発生する。磁束φ1,φ2は互いに逆向きの磁束であり、漏れ磁束φ3,φ4が発生する。ここで、図7に示すように、発生する漏れ磁束φ3,φ4に抗う方向に磁束を発生させるべく金属膜70の内部において誘導電流i10が周方向に流れる。
図8に示すように、金属膜70における放熱面Srが接している部位である第1直線部71には四角形状のスリット(貫通孔)75が形成されている。四角形状のスリット(貫通孔)75は、金属膜70の幅方向の中央部に位置し、平行なる長辺が金属膜70の長さ方向に延びるとともに平行なる短辺が金属膜70の幅方向に延びている。スリット75の形成領域は、図4(a)、図5に示すように、巻線60,61における放熱面Srに対向する面の一部を含んでいる。
帯状かつ無端状をなす金属膜70において、漏れ磁束に抗う方向に磁束を発生させようとして内部に電流が流れ、電力を消費して発熱する。
車載用電動圧縮機11における電動モータ19を駆動するインバータ装置30に用いられるコモンモードチョークコイル34は、導電体としての金属膜70で巻線60,61を覆うことでノーマルモード電流が流れる際に金属膜70の中に誘導電流を流し熱エネルギーに変換させダンピング効果を持たせる。なお、ダンピング効果を持たせるためには金属膜70にある程度の電気抵抗が必要となり、金属膜70は発熱する。
(1)電動圧縮機としての車載用電動圧縮機11の構成として、流体を圧縮する圧縮部18と、圧縮部18を駆動する電動モータ19と、電動モータ19を駆動するインバータ装置30と、少なくともインバータ装置30を収容する金属製のハウジング14と、を備える。インバータ装置30は、直流電力を交流電力に変換するインバータ回路31と、インバータ回路31の入力側に設けられるとともにインバータ回路31に入力される前の直流電力に含まれるコモンモードノイズ及びノーマルモードノイズを低減させるノイズ低減部32と、を備える。ノイズ低減部32は、コモンモードチョークコイル34と、コモンモードチョークコイル34と共にローパスフィルタ回路36を構成する平滑コンデンサとしてのXコンデンサ35と、を備える。コモンモードチョークコイル34は、環状のコア50と、コア50に巻回された第1の巻線60と、コア50に巻回されるとともに第1の巻線60から離れつつ対向する第2の巻線61と、第1の巻線60及び第2の巻線61を跨ぎつつコア50を覆う環状の導電体としての金属膜70と、を備える。金属膜70は、第1の巻線60と第2の巻線61の間において対向する部位同士が離れており、金属膜70は膜形状であって、金属膜70は、吸入ハウジング15ひいてはハウジング14に熱的に結合された放熱部としての第1直線部71を有し、金属膜70における周方向の単位長さあたりの電気抵抗の平均が、第1直線部71と、その他の部位とでは、第1直線部71のほうが大きい。
○ 図8においては金属膜70において長方形のスリット(貫通孔)75を形成したが、これに代わり図9に示すように金属膜70の幅方向において平行に延びる一対のスリット(貫通孔)76a,76bを形成してもよい。他にも、図10に示すように金属膜70の幅方向において平行に延びる一対のスリット(貫通孔)77a,77bを形成するとともにスリット(貫通孔)77a,77bに対し金属膜70の長さ方向に並べて配置されるスリット(貫通孔)77c,77dを形成してもよい。
○ 放熱グリス90に代わり放熱シートを用いてもよい。要は、熱伝導率が大きく熱伝導性に優れた放熱樹脂材を用いればよい。
○樹脂層80は、ポリイミドの他にも、ポリエステル、PET、PEN等で構成されていてもよい。
○樹脂層80を省き、代わりに別部材にて金属膜70を第1の巻線60および第2の巻線61に触れないよう支持してもよい。例えば、コア50を同形状の樹脂製ケースで覆い、金属膜70を第1の巻線60および第2の巻線61に触れないように挟持する一対の腕部材を当該ケースから延出形成してもよい。
○ 車載用電動圧縮機に限ることなく、車載用でない電動圧縮機に用いてもよい。
