Description

【０００１】
【発明の属する技術分野】
本発明は継鉄部と歯部とを連結し、スロット数と同数に分割した分割鉄芯板を用いたコンデンサ電動機固定子およびその製造方法に関する。
【０００２】
【従来の技術】
近年、複数に分割した分割鉄芯板に巻線を施工し分割鉄芯板を環状に配列してなる固定子とそれを製造する方法が普及されている。
【０００３】
従来、この種の固定子の製造方法の一例として特開平９−４６９７９号公報に記載されたものが知られていた。以下、その製造方法について図１６〜図１９を参照しながら説明する。
【０００４】
図１６および図１７に示すように、巻線１０１が巻回され、巻線１０１の巻始め部と巻終わり部となる中継ピン１０２を設けたコイルボビン１０３を各歯部１０４に挿入したのち、ヨーク１０５と合体して固定子を製造していた。
【０００５】
また、図１８および図１９に示すように、分割された歯部２０１にエンドインシュレータ２０２、２０３で絶縁処理をしたのち、巻線２０４の巻始め部と巻終わり部となる中継ピン２０５を設けて巻線２０４を巻装したのち、環状に合体して固定子を製造していた。
【０００６】
【発明が解決しようとする課題】
このような従来の固定子およびその製造方法では、前者においては、歯部１０４に設けられるコイルボビン１０３毎に巻線１０１の巻始め部と巻終わり部となる中継ピン１０２を設け、また、後者においては、分割された歯部２０１毎に巻線２０４の巻始め部と巻終わり部となる中継ピン２０５を設けていたので、前者および後者における中継ピン１０２と２０５の数量が多くなり、歯部１０４または、歯部２０１間を接続する渡り線処理が複雑となり、処理作業工数が多くなるという課題があった。
【０００７】
また、主巻線および補助巻線を極数個連続的に直巻巻装した主巻線巻装体および補助巻線巻装体を各々環状に配列した後、軸方向に移動させ前記主巻線巻装体と補助巻線巻装体が交互に環状に配列されるように一体化するとき、渡り線が組み合わせ作業の障害になる場合があるという課題があった。
【０００８】
本発明は上記課題を解決するもので、巻線の巻始め部と巻終わり部の数量を最小限にして、口出し線処理の作業工数の削減を図ることのできるコンデンサ電動機固定子およびその製造方法を提供することを目的とする。
【０００９】
また、主巻線巻装体と補助巻線巻装体との組合せ作業において、前記組合せ作業を容易にすることを目的とする。
【００１０】
【課題を解決するための手段】
本発明のコンデンサ電動機固定子の製造方法においては、外周に円弧面を有した継鉄部と、内面側に回転子対向面を形成した歯部とを連結し、スロット数と同数に分割した分割鉄芯板を打ち抜く打ち抜き工程と、前記分割鉄芯板を所定枚数積層し固定した分割鉄芯体を形成する積層工程と、前記分割鉄芯体に絶縁物を介し集中巻で主巻線を巻装し渡り線を介し主巻線巻装体を極数個連続的に直巻巻装する主巻線巻装工程と、前記分割鉄芯体に絶縁物を介し集中巻で補助巻線を巻装し、前記主巻線巻装体の渡り線を設けた主渡り線側とは分割鉄芯体を挟み軸方向の相反する側に配した補助渡り線側の渡り線を介して補助巻線巻装体を極数個連続的に直巻巻装する補助巻線巻装工程と、前記極数個の主巻線巻装体と前記極数個の補助巻線巻装体を各々環状に配列した後、この環状に配列した主巻線巻装体と同様に環状に配列した補助巻線巻装体を主渡り線側の反対側と補助渡り線側の反対側とを対向させ軸方向に移動させて組み合わせ、前記主巻線巻装体と補助巻線巻装体が交互に環状に配列されるように一体化する組立工程とにより製造するものである。
【００１１】
本発明によれば、巻線の巻始め部と巻終わり部の数量を最小限にして、口出し線処理の作業工数の削減を図ることができ、主巻線巻装体と補助巻線巻装体を軸方向に移動させて組み合わせるとき各々の渡り線が、組合せ作業の障害となることを防止できるコンデンサ電動機固定子の製造方法を提供することができる。
【００１２】
【発明の実施の形態】
本発明の請求項１に記載の発明は、外周に円弧面を有した継鉄部と、内面側に回転子対向面を形成した歯部とを連結し、スロット数と同数に分割した分割鉄芯板を打ち抜く打ち抜き工程と、前記分割鉄芯板を所定枚数積層し固定した分割鉄芯体を形成する積層工程と、前記分割鉄芯体に絶縁物を介し集中巻で主巻線を巻装し渡り線を介し主巻線巻装体を極数個連続的に直巻巻装する主巻線巻装工程と、前記分割鉄芯体に絶縁物を介し集中巻で補助巻線を巻装し、前記主巻線巻装体の渡り線を設けた主渡り線側とは分割鉄芯体を挟み軸方向の相反する側に配した補助渡り線側の渡り線を介して補助巻線巻装体を極数個連続的に直巻巻装する補助巻線巻装工程と、前記極数個の主巻線巻装体と前記極数個の補助巻線巻装体を各々環状に配列した後、この環状に配列した主巻線巻装体と同様に環状に配列した補助巻線巻装体を主渡り線側の反対側と補助渡り線側の反対側とを対向させ軸方向に移動させて組み合わせ、前記主巻線巻装体と補助巻線巻装体が交互に環状に配列されるように一体化する組立工程とにより製造する方法としたものであり、主巻線巻装体および補助巻線巻装体は渡り線を介し極数個連続的に製造することができることとなり、主巻線および補助巻線の巻始めと巻終わりは最小限の数量となり固定子の口出し線処理の作業工数の削減を図ることができ、主巻線巻装体と補助巻線巻装体を軸方向に移動させて組み合わせるとき各々の渡り線が、組合せ作業の障害となることを防止できるという作用を有する。
【００１３】
以下、本発明の実施の形態について図１〜図９を参照しながら説明する。
【００１４】
（実施の形態１）
図１〜図９に示すように、外周に円弧面を有し、連結面の一方に先細状の凸部１を設け、他方に先細状の凹部２を設けた継鉄部３と内周面に回転子対向面４を形成した歯部５とを連結し、スロット６の数と同数に分割した分割鉄芯板７を打ち抜く打ち抜き工程８と、打ち抜き工程８で打ち抜かれた分割鉄芯板７を所定枚数積層し、溶接等により固定した分割鉄芯体９を形成する積層工程１０と、積層工程１０で積層された分割鉄芯体９に絶縁物１１を介し、巻線機（図示せず）により集中巻で主巻線１２を巻装し渡り線１３を介し主巻線巻装体１４を極数個連続的に直巻巻装し端部に主巻線巻始め部１２ａと主巻線巻終わり部１２ｂを形成する主巻線巻装工程１５と、主巻線巻装工程１５とは別に分割鉄芯体９に絶縁物１１を介し集中巻で補助巻線１６を巻装し前記主巻線巻装体１４を設けた側とは固定子鉄芯を挟み軸方向の相反する側に配した渡り線１３を介し補助巻線巻装体１７を極数個連続的に直巻巻装し、端部に補助巻線巻始め部１６ａと補助巻線巻終わり部１６ｂを形成する補助巻線巻装工程１８と、主巻線巻装工程１５および補助巻線巻装工程１８で巻装され環状に配列した主巻線巻装体１４の渡り線１３を設けない側と環状に配列した補助巻線巻装体１７の渡り線１３を設けない側とを対向させて軸方向に組み合わせ、前記主巻線巻装体１４と補助巻線巻装体１７が交互に環状に配列する組立工程１９とにより成果物として固定子２０が製造されることとなる。
【００１５】
また、図９に示すように、主巻線巻装体１４の渡り線１３（図示せず）を有する主渡り線側２１と補助巻線巻装体１７の渡り線を有する補助渡り線側２２を固定子２０の軸方向の相反する側に配置する。
【００１６】
そして、主巻線巻装体１４および補助巻線巻装体１７を極数個連続的に直巻巻装するとき、主巻線巻装体１４および補助巻線巻装体１７を環状に配列し固定子２０を形成したときの隣極間の間隔とほぼ等しい間隔を保持しながら巻装し、主巻線巻装体１４および補助巻線巻装体１７の各極間の渡り線１３の長さを固定子２０の形成後の隣極間の間隔とほぼ等しい長さとする。
【００１７】
また、主巻線巻装工程１５および、補助巻線巻装工程１８においては、分割鉄芯体９をほぼ直線上に配列し、主巻線１２および、補助巻線１６の直巻巻装を行い主巻線巻装体１４および、補助巻線巻装体１７を製造する方法とする。
【００１８】
また、組立工程１９においては、主巻線巻装体１４と補助巻線巻装体１７を交互に環状に配列するとき、主巻線巻装体１４の凸部１は隣接する補助巻線巻装体１７の凹部２に対向させ、主巻線巻装体１４の凹部２には隣接する補助巻線巻装体１７の凸部１を対向させるようにして固定子外径を正規の寸法よりわずかに大寸の環状に配列し主巻線巻装体１４と補助巻線巻装体１７とが交互になるように仮配列させたのち、固定子外径寸法を正規の寸法になるように縮小し各凸部１と凹部２を嵌合させ一体化する製造方法とする。
【００１９】
また、主巻線巻装体１４と補助巻線巻装体１７双方の口出し線処理を主渡り線側２１で集中して行うか、補助渡り線側２２で集中して行うように主巻線巻始め部１２ａと主巻線巻終わり部１２ｂ、および補助巻線巻始め部１６ａと補助巻線巻終わり部１６ｂを同じ側に設けるものとする。
【００２０】
このように本発明の実施の形態１のコンデンサ電動機固定子およびその製造方法によれば、分割鉄芯体９に集中巻で主巻線１２を巻装し、渡り線１３を介し主巻線巻装体１４を極数個連続的に直巻巻装を行い、分割鉄芯体９に集中巻で補助巻線１６を巻装し渡り線１３を介し補助巻線巻装体１７を極数個連続的に直巻巻装し、主巻線巻装体１４と補助巻線巻装体１７を交互に環状に配列し固定子２０を製造するので、主巻線１２および補助巻線１６の巻始め、巻終わりの数量が最小限となり、固定子２０の口出し線処理時の作業工数の削減が可能となる。
【００２１】
また、主巻線巻装体１４の渡り線１３（図示せず）を有する主渡り線側２１と補助巻線巻装体１７の渡り線を有する補助渡り線側２２を固定子２０の軸方向の相反する側に配置することにより、主巻線巻装体１４と補助巻線巻装体１７を軸方向に組み合わせ交互に環状に配列して一体化するとき、主巻線巻装体１４の渡り線１３と補助巻線巻装体１７の渡り線１３とは分割鉄芯体を挟んで逆に位置することになり組立作業の障害になることが防止できる。
【００２２】
また、直巻巻装するとき、固定子２０を形成したときの隣極間の間隔とほぼ等しい間隔を維持し巻装するので、各極間の渡り線１３の長さを調整することなく主巻線巻装体１４と補助巻線巻装体１７を一体化することができる。
【００２３】
また、分割鉄芯体９をほぼ直線上に配列し、主巻線１２および補助巻線１６の直巻巻装を行うので、巻線機のノズルまたはフライヤーの回転スペースを十分に確保することができ、巻線巻装作業の効率化を図ることができる。
【００２４】
また、各極間の渡り線１３の長さを固定子２０形成後の隣極間の間隔とほぼ等しい長さとしたので、巻線巻装時、各巻線を巻装した極数個の主巻線巻装体１４および補助巻線巻装体１７の保持治具スペースを縮小し、巻線巻装装置の小型化を可能とすることができる。
【００２５】
また、主巻線巻装体１４および補助巻線巻装体１７の継鉄部３の連結面に設けた凸部１と凹部２を連結し固定子２０の外径寸法が正規の寸法よりわずかに大寸に配列したのち、固定子２０の外径寸法を正規の寸法に縮小するように凸部１と凹部２を嵌合し一体化するので、組合せ作業に要する原動費の削減および、組合せ部分の変形を防止できる。
【００２６】
また、主巻線巻始め部１２ａと主巻線巻終わり部１２ｂ、および補助巻線巻始め部１６ａと補助巻線巻終わり部１６ｂを主渡り線側２１または補助渡り線側２２に集中して設けることにしたので、口出し線処理作業、端子台の組み付け作業、および電気的接続作業が容易に短時間で実施でき、端子台構造の簡略化、小型化が可能となる。
【００２７】
なお、実施の形態１では、分割鉄芯板７を打ち抜く打ち抜き工程８と、分割鉄芯板７を積層して溶接等により固定し分割鉄芯体９を形成する積層工程１０により製造する方法を説明したが、プレス機で分割鉄芯板を打ち抜きながら、結合部を介し順次積層して分割鉄芯体を製造する場合も本発明に含まれるものである。
【００２８】
（実施の形態２）
図１０および図１１に示すように、分割鉄芯板９Ａをほぼ円形状に配列し主巻線１２を集中巻で巻装し渡り線１３を介し、主巻線巻装体１４Ｂを極数個連続的に直巻巻装する。
【００２９】
また、ほぼ円形状に配列した分割鉄芯板９Ａに補助巻線１６を集中巻で巻装し渡り線１３を介し補助巻線巻装体１７Ｂを極数個連続的に直巻巻装する。
【００３０】
そして、主巻線巻装体１４Ｂと補助巻線巻装体１７Ｂを交互に環状に配列して固定子（図示せず）を形成する。
【００３１】
このように本発明の実施の形態２のコンデンサ電動機固定子の製造方法によれば、分割鉄芯体９Ａをほぼ円形状に配列し主巻線１２および補助巻線１６の直巻巻装を行うので、主巻線巻装体１４Ｂおよび補助巻線巻装体１７Ｂは固定子に一体化するときの配列と同等であるので、主巻線巻装体１４Ｂおよび補助巻線巻装体１７Ｂを直線状に配列した場合のように、直線状から円形状に再配列する必要性が無く、また、各極間の渡り線１３の保持構造を変更する必要性も無くなる。
【００３２】
（実施の形態３）
図１〜図３および図１２〜図１５に示すように、外周に円弧面を有し、連結面の一方に先細状の凸部１を設け、他方に先細状の凹部２を設けた継鉄部３と内周面に回転子対向面４を形成した歯部５とを連結し、スロット６の数と同数に分割した分割鉄芯板７を打ち抜く打ち抜き工程と、打ち抜き工程で打ち抜かれた分割鉄芯板７を所定枚数積層し、溶接等により固定した分割鉄芯体９Ｂを形成する積層工程と、積層工程で積層された分割鉄芯体９Ｂに絶縁物１１を介し、巻線機（図示せず）により集中巻で主巻線１２を巻装し主巻線巻装体１４Ｃを極数個直巻巻装する主巻線巻装工程と、主巻線巻装工程とは別に分割鉄芯体９Ｂに絶縁物１１を介し集中巻で補助巻線１６を巻装し補助巻線巻装体１７Ｃを極数個直巻巻装する補助巻線巻装工程と、主巻線巻装工程および補助巻線巻装工程で巻装され環状に配列した主巻線巻装体１４Ｃと環状に配列した補助巻線巻装体１７とを対向させて軸方向に組み合わせ、前記主巻線巻装体１４Ｃと補助巻線巻装体１７Ｃが交互に環状に配列する組立工程とにより成果物として固定子２０Ａが製造されることとなる。このとき前記組立工程においては、極数個の主巻線巻装体１４Ｃおよび補助巻線巻装体１７Ｃは各々環状に、そして正規の寸法よりわずかに大寸に配列したまま主巻線巻装体１４Ｃと補助巻線巻装体１７Ｃを対向させ、固定子外径寸法を正規の寸法よりわずかに大寸としたまま交互に位置するように軸方向に移動させて組み合わせ、環状に仮配列したのち固定子外径寸法が正規の寸法になるように縮小して一体化することで固定子２０Ａを形成する。
【００３３】
また、極数個の主巻線巻装体１４Ｃと極数個の補助巻線巻装体１７Ｃを交互に位置するように前記主巻線巻装体１４Ｃと補助巻線巻装体１７Ｃを一個ずつまたは複数個ずつ、正規の固定子外径寸法よりわずかに大寸の環状に配列したのち、正規の寸法に縮小して一体化することで固定子２０Ａを形成する。
【００３４】
このように本発明の実施の形態３のコンデンサ電動機固定子によれば、ほぼ円形状に配列した主巻線巻装体１４Ｃおよび補助巻線巻装体１７Ｃを固定子外径の正規の寸法よりわずかに大寸のまま軸方向に組み合わせた後に正規の寸法に縮小一体化するため、主巻線巻装体１４Ｃおよび補助巻線巻装体１７Ｃの組合せ時の原動力の削減と主巻線巻装体１４Ｃと補助巻線巻装体１７Ｃの組合せ部分の変形を防止できる。
【００３５】
また、極数個の主巻線巻装体１４Ｃと極数個の補助巻線巻装体１７Ｃを交互に位置するように前記主巻線巻装体１４Ｃと補助巻線巻装体１７Ｃを一個ずつまたは複数個ずつ、正規の固定子外径寸法よりわずかに大寸の環状に配列したのち、正規の寸法に縮小して一体化する製造工程としたので、主巻線巻装体１４Ｃと補助巻線巻装体１７Ｃの組み合わせ部分の変形を防止でき、最小限の簡略的な設備で本構造の固定子２０Ａの製造ができる。
【００３６】
【発明の効果】
以上の実施の形態から明らかなように、本発明によれば、外周に円弧面を有した継鉄部と、内面側に回転子対向面を形成した歯部とを連結し、スロット数と同数に分割した分割鉄芯板を打ち抜く打ち抜き工程と、前記分割鉄芯板を所定枚数積層し固定した分割鉄芯体を形成する積層工程と、前記分割鉄芯体に絶縁物を介し集中巻で主巻線を巻装し渡り線を介し主巻線巻装体を極数個連続的に直巻巻装する主巻線巻装工程と、前記分割鉄芯体に絶縁物を介し集中巻で補助巻線を巻装し、前記主巻線巻装体の渡り線を設けた主渡り線側とは分割鉄芯体を挟み軸方向の相反する側に配した補助渡り線側の渡り線を介して補助巻線巻装体を極数個連続的に直巻巻装する補助巻線巻装工程と、前記極数個の主巻線巻装体と前記極数個の補助巻線巻装体を各々環状に配列した後、この環状に配列した主巻線巻装体と同様に環状に配列した補助巻線巻装体を主渡り線側の反対側と補助渡り線側の反対側とを対向させ軸方向に移動させて組み合わせ、前記主巻線巻装体と補助巻線巻装体が交互に環状に配列されるように一体化する組立工程とにより製造するので主巻線および補助巻線の巻始め部と巻終わり部の数を最小限にし、固定子の口出し線処理時の作業工数の削減を図ることのでき、主巻線巻装体と補助巻線巻装体を軸方向に移動させて組み合わせるとき各々の渡り線が、組合せ作業の障害となることを防止できるコンデンサ電動機固定子の製造方法を提供できる。
【００３７】
また、主巻線巻装体および補助巻線巻装体を極数個連続的に直巻巻装するとき、主巻線巻装体および補助巻線巻装体を環状に配列し固定子を形成したときの隣極間の間隔とほぼ等しい間隔を維持し巻装するので、各極間の渡り線の長さを調整することなく、主巻線巻装体と補助巻線巻装体を一体化することができる。
【００３８】
また、分割鉄芯体をほぼ直線上に配列し、主巻線および補助巻線の直巻巻装を行い主巻線巻装体および補助巻線巻装体を製造するので、巻線機のノズルまたはフライヤーの回転スペースを十分に確保することができ、巻線巻装作業の効率化が可能となる。
【００３９】
また、主巻線巻装体および補助巻線巻装体の各極間の渡り線の長さを、固定子形成後の隣極間の間隔とほぼ等しい長さとしたので、巻線巻装時に、主巻線を巻装した極数個の主巻線巻装体および補助巻線を巻装した極数個の補助巻線巻装体の保持治具スペースを縮小し巻線巻装装置を小型化することができる。
【００４０】
また、継鉄部の連結面の一方に先細状の凸部を設け、他方に先細状の凹部を設けた主巻線巻装体および補助巻線巻装体を前記凸部と凹部を順次連結し環状に仮配列したのち固定子外径寸法を正規の寸法に縮小するように前記凸部を凹部に嵌合し一体化させ製造するので、正規寸法に一体化することが可能で組み合わせ作業に要する原動費の削減および組合せ部の変形が防止できる。
【００４１】
また、主巻線巻装体と補助巻線巻装体の口出し線処理を主渡り線側または補助渡り線側で集中し行うようにしたので、口出し線処理作業、端子台の組み付け、および電気的接続が容易に短時間で実施でき、端子台構造の簡略化、小型化が可能となる。
【００４２】
また、分割鉄芯体をほぼ円形状に配列し、主巻線および補助巻線の直巻巻装を行い主巻線巻装体および補助巻線巻装体を製造するので、主巻線巻装体および補助巻線巻装体は一体化後の配列と同等となり、主巻線巻装体および補助巻線巻装体を直線状から円形状に再配列する必要性が無く、また、各極間の渡り線の保持構造を変更する必要も無くなるという効果が得られる。
【００４３】
また、外周に円弧面を有し、内面側に回転子対向面を形成したスロット数と同数の分割鉄芯体と、この分割鉄芯体に主巻線を巻装し、渡り線を介して極数個連続的に直巻巻装した主巻線巻装体と、前記分割鉄芯体に補助巻線を巻装し、渡り線を介して極数個連続的に直巻巻装した補助巻線巻装体とを設け、前記主巻線巻装体の渡り線を設けた主渡り線側と前記補助巻線の渡り線を設けた補助渡り線側が固定子の軸方向の相反する側に配置されるように前記主巻線巻装体と前記補助巻線巻装体とを交互に環状に配列してなるコンデンサ電動機固定子であるので、主巻線および補助巻線の巻始め、巻終わりの数量が最小限となる。
【００４４】
また、主巻線および補助巻線の巻始め部と巻終わり部とを、主渡り線側または補助渡り線側に集中して設けたので、端子台構造の簡略化、小型化が可能となる。
【００４５】
また、極数個の主巻線巻装体と極数個の補助巻線巻装体を独立して設け、主巻線巻装体および補助巻線巻装体を交互に環状に、そして正規の固定子外径寸法よりもわずかに大寸に仮配列したのち正規の寸法に縮小し一体化するので、主巻線巻装体および補助巻線巻装体の組み合わせ作業が容易となり、組み合わせ作業に要する原動費の削減および組み合わせ部の変形が防止できる。

また、極数個の主巻線巻装体と極数個の補助巻線巻装体が交互に位置するように前記主巻線巻装体と補助巻線巻装体を一個ずつまたは複数個ずつ、正規の固定子外径寸法よりわずかに大寸の環状に配列したのち、正規の寸法に縮小して一体化する製造工程としたので、主巻線巻装体と補助巻線巻装体の組み合わせ部分の変形を防止でき、低コストで簡略的な設備により製造することができる。
