Abstract
Description
この発明は、上記課題を解決するためになされたもので、界磁コイルと爪状磁極との電気的絶縁性を確保したまま、界磁コイル巻線の引出し線の巻回作業時の、カバー部と巻線、または、カバー部と巻線巻回用治具との干渉を抑制した回転電機の回転子を得ることを目的とする。さらに多極化、小型化の実現も図る。
係止部は、界磁コイルが巻回される係止頸部、係止頸部から周方向に延在する抜け止め部からなり、抜け止め部の係止頸部から周方向一方に延在する長さは周方向他方に延在する長さより長いことを特徴とする。
また、この発明に係わる回転電機の回転子は、爪状磁極を有し、シャフトを軸として一体に回転する界磁コアと、界磁コアに固定され、界磁コイルを巻回するための巻線部、巻線部の軸方向両側に設けられた鍔部、鍔部から径方向外側に延設され、界磁コイルの少なくとも一方の端部が係止される係止部、鍔部上に周方向から軸線方向に突出して複数配設された回り止め部、を有するボビンと、を備え、
係止部は、界磁コイルが巻回される係止頸部、係止頸部から周方向に延在する抜け止め部からなり、係止頸部の周方向中央は、回り止め部の周方向中央よりボビン巻回し後方にずれて配置されていることを特徴とする。
実施の形態1.
図1はこの発明の実施の形態1による回転電機の回転子構造を示す断面図、図2は図1の回転子が備える絶縁ボビンとそれに巻回された界磁コイルを示す斜視図、図3は、図1の係止部周辺の拡大図である。
回転電機の回転子1は、絶縁ボビン5、絶縁ボビン5に導線が複数層にわたって巻回され、電流を流して磁束を発生する界磁コイル2、この界磁コイル2を覆って設けられた界磁コアを有する。この界磁コアは、界磁コア体3と界磁コア体4からなり、それぞれの界磁コア体3及び4は、交互に噛み合うように設定された爪状磁極(クローポール)を有する。また、界磁コア体3の端面にファン11が固定され、界磁コア体4の端面にはファン12が固定されている。
界磁コイル2および界磁コアはシャフト13に固定され、シャフト13は、フロント軸受(図示せず)とリア軸受(図示せず)により両端部がそれぞれ回転自在に支持される。シャフト13の一端部にプーリ(図示せず)が固定され、他端に界磁コイル2に電流を供給するスリップリングアッセンブリ7を備える。スリップリングアッセンブリ7は、図示しないブラシを介して2つのスリップリングへ電流を外部から供給するように構成されている。
引出し線6は、界磁コイル2が絶縁ボビン5に周回された後、その終端21が係止部14の係止部頸部141に周回されてなる第一周回部61、これに続く第二周回部62、引出し線スリップリング接続部63からなる。係止部頸部141からさらに径方向に延設され、周方向に延びる係止部抜け止め部142により、第一および第二の周回部61,62は、径方向の移動を規制される。図4および図5に示すように、係止部抜け止め部142は、第一周回部61の径方向外側に第二周回部62が重ねられる側(ボビン巻回し前方)において、第二周回部62が重ねられない側(ボビン巻回し後方)の長さBWよりも、係止部頸部141から周方向に延出する長さFWが長く構成される(FW>BW)。これにより、第一周回部61および第二周回部62が係止部頸部141から離脱することを抑制する。また、第二周回部62が重ねられない側(ボビン巻回し後方)については、係止部頸部141から周方向に延出する長さBWを最小限長さにでき、多極化された回転子に対応可能となる。さらに、第一周回部61の径方向外側に第二周回部62が重ねられる側(ボビン巻回し前方)において、係止部抜け止め部142には、径方向内側に突出した係止部突起部143が形成されており、第一および第二の周回部61、62が係止部頸部141から浮いてしまわないよう規制する。
上記回り止め部52は、基本的に略U字状で設けられ、その周方向中央MTは、界磁コア体3、4それぞれの隣り合う爪状磁極間の谷部中央に沿った形状で設けられるので、係止部頸部141の周方向中央(KT)は爪状磁極間の谷部中央に対しても巻回し後方にずれた状態となっている。
また、上記実施の形態では、係止部14を巻き終わりに施したが、類似形状で巻始めに設けてもよい。その場合は、ボビン巻回し前方か後方かに限定されず、二回り巻回される側の係止部抜け止め部周方向延出長さを長く設定すればよい。
なお、この発明は、その発明の範囲内において、実施の形態を適宜、変形、省略することが可能である。
