Description
【０００１】
【発明の属する技術分野】
本発明は、回転電機の固定子に関するもので、特に固定子に巻装したコイルの相間絶縁構造に関するものである。
【０００２】
【従来の技術】
従来の回転電機の固定子の構成は、図５に示すように構成されている。薄鋼板より外側円弧部１４と内側円弧部１５とこれら円弧部を接続する連結巻線部１６とを一体に打ち抜き積層した分割鉄心１３を設け、この分割鉄心１３の連結巻線部１６にコイルボビン１７を取付け、このコイルボビン１７の外周に電線を巻装してコイル１８を形成した分割鉄心１３を周方向に並べて回転電機の固定子を構成し、この固定子のコイル１８間および分割鉄心の外周にモールド樹脂１９を充填して巻線の相間絶縁を行っていた。
【０００３】
【発明が解決しようとする課題】
このように構成した回転電機の固定子は、モールド樹脂を充填するとき整列巻で巻かれたコイルがモールド時の圧力で崩れて他相のコイルに近接あるいは接触して絶縁が確保できなくなる恐れがあるという問題があった。
そこで、本発明は、樹脂をモールドする固定子においても簡単で、かつ確実にコイルの絶縁ができるようにすることを目的とする。
【０００４】
【課題を解決するための手段】
本発明は、上記目的を達成するために、外側円弧部と内側円弧部とこれら円弧部を接続する連結巻線部とを一体に薄鋼板から打ち抜き積層し、前記連結巻線部に装着したコイルボビンにコイルを巻装した分割鉄心を周方向に並べ、コイル部およびコイル間にモールド樹脂を充填した回転電機の固定子において、軸方向に延びる複数枚の板状の相間絶縁部と、この相間絶縁部と垂直方向に交わるように一体に連結した複数個の穴を有する板状の環状体部とで相間絶縁体を構成し、前記相間絶縁体の前記相間絶縁部を、相隣り合うコイル間に介装するとともに、前記相間絶縁部を囲み分割鉄心のコイル間に、モールド樹脂を充填するようにしている。
【０００５】
【発明の実施の形態】
以下、本発明を図に示す実施例に基づいて説明する。
図１は、本発明の第１の実施例における回転電機の固定子の上半部を示す正断面図で、コイルおよびコイルボビンの一部を省略している。図２は、第１の実施例における分割鉄心およびコイルボビンの斜視図、図３は、第１の実施例における相間絶縁体の斜視図である。
図において、１は分割鉄心で、薄鋼板より外側円弧部２と内側円弧部３およびこれら円弧部を接続する連結巻線部４とを一体に打ち抜き積層して構成している。５は絶縁材よりなり分割鉄心１の連結巻線部４に取付けたコイルボビン、６はコイルボビン５に巻装したコイル、７は絶縁材よりなる相間絶縁体で、軸方向に延びる複数枚の板状の相間絶縁部８と、この相間絶縁部８と垂直方向に交わるように一体に連結した複数個の穴１０を有する板状の環状体部９とで構成され、前記相間絶縁体７の前記相間絶縁部８を、相隣り合うコイル６間に介装している。環状体部９の板面には複数の穴１０が設けられている。１１はコイルの外周に充填した絶縁材よりなるモールド樹脂である。
このような回転電機の固定子は、分割鉄心１の連結巻線部４にコイルボビン５を取付け、このコイルボビン５にコイル６を巻装した分割鉄心１を周方向に並べて外側円弧部２を連結して固定し、相間絶縁体７の相間絶縁部８をコイル間に介装し、相間絶縁体７の環状体部９の穴１０より相間絶縁部を囲み前記コイル６の外周およびコイルエンド部にモールド樹脂１１を充填して構成する。
図４は、第２の実施例を示すもので、コイルボビン５のつばに曲折できる相間絶縁部１２を設け、コイルボビン５に電線を巻装してコイル６を構成し、前記相間絶縁部１２を折り曲げてコイルの側面を相間絶縁部で覆うた後、モールド樹脂１１を充填して構成する。
【０００６】
【発明の効果】
以上述べたように、本発明によれば、固定子に巻装したコイル間に、相間を絶縁する相間絶縁部を介装して樹脂をモールドするので、コイルは強いモールド圧を受けてもコイルがずれて相間の絶縁不良を生ずることがない。
