この端子１０１のフック１０８にコイルの端末１１０を引っ掛け、半田、あるいは、ヒュージング等で結線されるが、コイルの端末１１０を位置決するために、端子１０１を備えたティース１０７の外径側絶縁部１０５にコイルの巻付け部１１１を捨てからげる捨てからげ用突起１０２が設けられていた。
【０００４】
【発明が解決しようとする課題】
従来の電動機の固定子は以上のように構成されているので、端子１０１のフック１０８に引っ掛けたコイル端末１１０を位置決めするためにコイルの巻付け部１１１を捨てからげ用突起１０２に捨てからげるが、固定子の外径に対してティース１０７の数が多い場合は外径側絶縁部１０５が小さい、あるいは、端子１０１の位置の関係等により、端子１０１を備えた外径側絶縁部１０５に捨てからげ用突起１０２を形成するスペースの確保が出来ないという問題点があった。
【０００５】
この発明は、上記のような問題点を解決するためになされたもので、コイル端末の引き回しに十分なスペースを確保出来、生産性及び品質の向上を図ることが出来る電動機の固定子を得ることを目的とする。
【０００６】
【課題を解決するための手段】
この発明に係る電動機の固定子は、ティースに設けられた絶縁部にマグネットワイヤーが巻付けられることによりコイルが形成され、各コイルは、コイルの巻始め端末から始まり、ティース間を渡り線で渡り別のコイルを形成し、コイルの巻終り端末で終了し、巻始めと巻終りのコイルの絶縁部に端子を備え、各コイル端末が端子と結線され、端子を介してコイルに電力が供給される電動機の固定子において、コイル端末を捨てからげる捨てからげ用突起を、コイル端末を結線する端子を設けないティースの絶縁部に備えたものである。
【０００７】
また、コイル端末を結線する端子を絶縁部に備えたティースと隣り合うティースの絶縁部に捨てからげ用突起を備えたものである。

また、端子と結合される基板又は結線用部品を備え、捨てからげ用突起の上面を基板又は結線用部品の設置面としたものである。
【００１１】
また、絶縁部に基板取付け突起を設け、この基板取付け突起と基板に設けた取付け穴とを嵌め合わし、基板の取付け穴から出た基板取付け突起を熱で溶かして基板を固定するものである。
【００１２】
この発明に係る電動機は、請求項１〜５のいずれかに記載の電動機の固定子を用いたものである。
【００１３】
この発明に係る空気調和機は、冷凍サイクルを備えた空気調和機において、請求項６記載の電動機を送風機に用いたものである。
【００１４】
【発明の実施の形態】
実施の形態１．
以下、この発明の実施の形態１を図面を参照して説明する。
図１〜３は実施の形態１を示す図で、図１は電動機の固定子全体を示す斜視図、図２はコイルの巻始めの構成を示す図、図３はコイルの巻終りの構成を示す図である。
【００１５】
図１において、１は巻始め、又は巻終りのコイルの端末を結線する端子、２はコイルの端末を位置決するための捨てからげ用突起、３は鋼板を積層した固定子鉄心、４は電力が供給されるコイル、５は固定子の外径側に設けられた外径側絶縁部、６は固定子の内径側に設けられた内径側絶縁部である。
【００１６】
図２は連続して巻かれるコイルの巻始めの構成を示すが、図において、７は固定子鉄心３のティース、８は端子１に設けられたコイルの端末を引っ掛けるためのフック、９はコイル４の巻始め端末を示す。
【００１７】
図３は連続して巻かれるコイルの巻終りの構成を示すが、図において、４ａは或るティース７に最初に巻かれるコイル、４ｂは次のティース７に２番目に巻かれるコイル、４ｃはまた次のティース７に最後に巻かれるコイル、１０はコイル４ｃから出るコイルの巻終り端末、１１は捨てからげ用突起２に捨てからげるコイル端末の巻付け部、１２はコイル４ａとコイル４ｂ、又はコイル４ｂとコイル４ｃ間の渡り線、１３は端子１の絶縁部を示す。
【００１８】
固定子鉄心３に一体成形、または、部品の組付けによりそれぞれのティース７に絶縁部が形成され、ティース７に設けられた絶縁部にマグネットワイヤーが巻付けられることによりコイルが形成される。各コイルは、コイルの巻始め端末９から始まり、ティース７間を渡り線１２で渡り、別のコイルを形成し、コイルの巻終り端末１０で終了する。
【００１９】
巻始めと巻終りのコイルの外径側絶縁部５に端子１を備え、各コイル端末が端子１と結線され、端子１を介してコイルに電力が供給される。端子１とコイル端末の結合に関して、端子１にコイル端末を結合する部分にフック８を設けてヒュージング、あるいは、半田等により、コイル端末と端子１とが結合されるが、両者を結合する工程を終了するまでは、コイル端末を保持する必要があるため、捨てからげ用突起２を設け、コイル端末の巻付け部１１を巻付けることにより、端子１と結合されるコイル端末部が位置決めされる。
【００２０】
ここで、巻始めと巻終りの外径側絶縁部５に設けられる端子１の位置に関して、ティース７にマグネットワイヤーを巻付ける方向、フック８とティース７間のマグネットワイヤーの引き回し、コイルの巻線方法、あるいは、端子１とコイル端末の結線方法等の関係により、端子１、端子１のフック８の位置も決定される。
【００２１】
前述の理由、あるいは、固定子の外径に対してティース数が多い場合等、端子１を備えた外径側絶縁部５に捨てからげ用突起２を設けることが出来ない場合も発生する。このような場合に、絶縁部にコイル端末を結線する端子１を備えたティース７に隣接し、絶縁部に端子１がないティース７の外径側絶縁部５に捨てからげ用突起２を設けることが有効である。
【００２２】
具体的には、図２，３に示すように、コイルの巻始め端末９は２番目に巻かれるコイル４ｂの外径側絶縁部５に設けられた捨てからげ用突起２に巻付けられ、最初に巻かれるコイル４ａの外径側絶縁部５に設けられた端子１の８フックを通り、絶縁部を備えたティースに巻付けられ、最初に巻かれるコイル４ａが形成される。
【００２３】
最初に巻かれるコイル４ａの巻終り端末を切断することなく、渡り線１２として、２番目に巻かれるコイル４ｂのティース７まで引き回される。この時、渡り線１２は端子１が挿入された絶縁部側を引き回すことから、端子１との接触を避けるために、端子１が設けられた外径側絶縁部５に端子の絶縁部１３を設けている。
【００２４】
２番目に巻かれるコイル４ｂのティース７まで引き回された渡り線１２は、そのまま切断されることなく２番目のコイルを形成し、最初に巻かれるコイル４ａと同様にコイルの巻終り端末を切断することなく、渡り線１２として、３番目に巻かれるコイル４ｃのティース７まで引き回される。
【００２５】
また、３番目に巻かれるコイル４ｃの外径側絶縁部５に設けられた端子１についても最初に巻かれるコイル４ａの外径側絶縁部５と同様に、渡り線１２は端子１が挿入された絶縁部側を引き回すことから、端子１との接触を避けるために、端子１が設けられた外径側絶縁部５に端子の絶縁部１３を設けている。
【００２６】
そして、最後の３番目に巻かれるコイル４ｃのティース７まで引き回された渡り線１２は、前の２番目に巻かれるコイル４ｂと同様に切断されることなく３番目に巻かれるコイル４ｃを形成する。３番目に巻かれるコイル４ｃを巻終えたコイル端末は、３番目に巻かれるコイル４ｃの外径側絶縁部５に設けられた端子１のフック８を通り、２番目に巻かれるコイル４ｂの外径側絶縁部５に設けられた捨てからげ用突起２に巻付けられ、フック８に入る巻終りのリード端末を位置決めする。端子１のフック８と各コイル端末はヒュージング、あるいは、半田等で結線される。
【００２７】
本実施の形態では、隣り合うティースに連続してコイルを形成する固定子を示したが、ティースをとばして連続してコイルを形成する場合も、本発明が適用されることはいうまでもない。
【００２８】
また、巻始めコイル，巻終りコイルのそれぞれの外径側絶縁部５に端子１を備えた固定子を示しているが、捨てからげ用突起２と端子１の位置関係が、全て、あるいは、一部のみが入れ替わっていても本発明が適用されることは言うまでもない。
【００２９】
上述の実施の形態１によれば、固定子の外径側絶縁部５にコイル端末を結線する端子１を備えたティース７に隣接し、端子１がないティース７に捨てからげ用突起２を設けることで、コイル端末の引き回しに十分なスペースを確保出来ることから、生産性の向上と、これに伴う品質の向上が得られる。
【００３０】
実施の形態２．
以下、この発明の実施の形態２を図面を参照して説明する。
図４は実施の形態２を示す図で、段差を備えた捨てからげ用突起の構成を示す斜視図である。
図において、１１はコイル端末の巻付け部、１４は捨てからげ用突起の段差を示す。外径側絶縁部５に設けられた捨てからげ用突起２は、コイル端末の位置決め、あるいは、渡り線１２の引っ掛け部として機能するが、捨てからげ用突起２に段差を設けることにより、各コイル端末の巻付け部１１のずれ防止、あるいは、渡り線１２のティースに対する位置決め、あるいは、各コイル端末と渡り線１２との接触を避けることが可能となる。尚、その他の機能，構成は実施の形態１で示される特徴と同様である。
【００３１】
実施の形態３．
以下、この発明の実施の形態３を図面を参照して説明する。
図５は実施の形態３を示す図で、基板を備えた固定子の構成を示す図である。図において、１５は基板、１６は基板設置面、１７は基板取付け突起を示す。
【００３２】
固定子に設けられた端子１は、基板１５と結合され、コイル４に基板１５と端子１を介して電力が供給されるが、端子１と結線部品とを結合するために、両者を所定の位置で保持する必要がある。ここで、捨てからげ用突起２の上面を基板１５の設置面とし、外径側絶縁部５に設けた基板取付け突起１７と基板１５に設けた取付け穴とを嵌め合わし、基板１５の取付け穴から出た基板取付け突起１７を熱で溶かして基板１５を固定する。その後に、所定の位置に保持された基板１５と端子１とを半田等で結合することにより組立てられる。尚、その他の機能，構成は実施の形態１，２で示される特徴と同様である。
【００３３】
上述の実施の形態によれば、捨てからげ用突起２の上面に基板１５を設置することにより、端子１と基板１５との位置を保持できるため、生産性の向上と、それに伴う品質の向上が得られる。
【００３４】
上述の実施の形態では、基板１５を使用しているが、基板１５に代わる部品を使用した場合も、本発明が適用されることは言うまでもない。

【００３６】
前述の実施の形態で示した固定子の構成を、薄肉連結鉄心に適用した場合を図６に示しているが、例えば、アウターロータ型の電動機の固定子で端子が内径側絶縁部にある場合等、固定子の形態にかかわらずに本発明が適用されることは言うまでもない。
【００３７】
また、本発明で示す電動機の固定子をモールドで封入するモールド電動機を図７に示すが、外郭の形態にかかわらず、本発明が適用されることは言うまでもない。
【００３８】
