Description

【０００１】
【発明の属する技術分野】
本発明は、発電・電動機用ステータの製造方法及びその組立治具に関する。
【０００２】
【従来の技術】
発電・電動機用ステータの製造方法及びその組立治具が知られている（例えば、特許文献１参照。）。
【０００３】
【特許文献１】
特開平１１−１５０９０４号公報（第８頁、図５−６）
【０００４】
同公報の図５及び図６を再掲し上記技術を説明する。ただし、同公報に記載の符号を新しく振り直すとともに記載の名称も一部変更した。
図１８は特開平１１−１５０９０４号公報の図５の再掲図であり、ステータコイルの接続回路を示す。また、図１９は特開平１１−１５０９０４号公報の図６の再掲図あり、ステータコイルの接続端子を示す。
ステータ１００は、ステータコア（不図示）に複数の第１コイル部１０１・・・（・・・は複数個を示す。以下同じ）を形成することで第１系統の巻線コイル１０５を形成し、ステータコアに複数の第２コイル部１０２・・・を形成することで第２系統の巻線コイル１０６を形成し、ステータコア（不図示）に複数の第３コイル部１０３・・・を形成することで第３系統の巻線コイル１０７を形成し、これらの第１〜３系統の巻線コイル１０５〜１０７の巻始め若しくは巻終りの端部１０８・・・を図１８に詳細形状を示す接続端子１０９・・・にそれぞれ接続する。
【０００５】
【発明が解決しようとする課題】
しかし、特許文献１のステータ１００では、第１〜３系統の巻線コイル１０５〜１０７の巻始めの若しくは巻終りの端部１０８・・・を、把持工具等で把持してそれぞれ接続端子１０９・・・に接続し、接続後、巻線コイル１０５〜１０７の巻始め若しくは巻終りの端部１０８・・・を切断するものであり、少なくとも６箇所の接続作業及び切断作業が発生する。従って、ステータ１００の組立作業に多大の時間がかかる。
【０００６】
そこで、本発明の目的は、巻線コイルの巻始めの端部及び巻終りの端部の接続作業及び切断作業を短時間で行うことができる発電・電動機用ステータの製造方法及びその組立治具を提供することにある。
【０００７】
【課題を解決するための手段】
上記目的を達成するために請求項１の発電・電動機用ステータの製造方法は、リング状のヨークから放射状に複数のティースを突出させてなるステータコア、下インシュレータ及び複数の接続端子を備えた上インシュレータを準備する準備工程と、ステータコアの上から上インシュレータを取付けるとともにステータコアの下から下インシュレータを取付けるインシュレータ取付け工程と、上・下インシュレータを取付けたステータコアを基台に装着するステータコア装着工程と、基台に巻線材の巻始め端を係止する巻始め端係止工程と、基台に向かって先細りテーパ形状に形成され、基台の中心に取付けた円錐形状の巻付け部材に巻線材を巻付ける巻線材巻付け工程と、巻線材を複数の接続端子の一つを経由させて、複数のティースの内の最初のティースに巻線材を導く巻線材導入工程と、巻線材に所定のテンションを保ちながら最初のティースに巻線材を巻くことで最初のコイル部を形成し、巻線材に所定のテンションを保ちながら次に巻線を施すティース位置までステータコアを回転させて所定のティースに連続的に巻線を施すことで最終のティースまでコイル部を形成するコイル部巻回工程と、巻線材を複数の接続端子の他の一つを経由させて巻付け部材に戻すことでコイル部を連続させた最初の系統の巻線コイルを完成させる巻線材戻し工程と、これらの巻線材巻付け工程、巻線材導入工程、コイル巻回工程及び巻線材戻し工程を複数回繰り返すことで複数の系統の巻線コイルを連続的に形成する巻線コイル連続工程と、複数の巻線コイルの接続端子にそれぞれ経由させた部分を前端部及び後端部と呼ぶときに、これらの前端部及び後端部を接続端子に同時に接続する接続端子接続工程と、前端部及び後端部を一括して切断する巻線材切断工程と、から構成したことを特徴とする。
【０００８】
請求項１記載の発電・電動機用ステータの製造方法によれば、複数の系統の巻線コイルを連続的に形成することで、複数の系統の巻線コイルを切らずに連続して巻くことができる。この結果、複数の系統の巻線コイルを巻回する作業時間の短縮を図ることができる。
【０００９】
複数の系統の巻線コイルの前端部及び後端部を接続端子に同時に接続することで、接続時間の短縮を図ることができる。
複数の系統の巻線コイルの前端部及び後端部を一括して切断することで、切断に要する時間の短縮を図ることができる。
【００１０】
請求項２の発電・電動機用ステータの組立治具は、リング状のヨークから放射状に複数のティースを突出させたステータコアに巻線を施すときに使用する発電・電動機用ステータの組立治具において、ステータコアを載置する基台と、この基台の中心に設けることでティースにコイル部を形成するときに巻線材を巻付ける円錐形状の巻付け部材と、を備え、巻付け部材に、巻線材を巻付ける筒部と、この筒部から基台に向かって先細りテーパ形状に延出するとともにステータコアの上面レベルに設定することで、巻線材を巻付けたときに巻線材を筒部に誘導するテーパ部と、このテーパ部に巻線材を導くためのすり割り部とを備えたことを特徴とする。
【００１１】
一般的に、ステータコアは、リング状のヨークから放射状に複数のティースを突出させた形状を呈する。
そこで、ティースにコイル部を形成するときに巻線材を巻付ける円錐形状の巻付け部材を設けた。巻付け部材に、巻線材を巻付ける筒部と、この筒部から基台に向かって先細りテーパ形状に延出するとともにステータコアの上面レベルに設定することで、巻線材を巻付けたときに巻線材を筒部に誘導するテーパ部と、このテーパ部に巻線材を導くためのすり割り部とを備えた。例えば、巻線材の巻始めの端部若しくは巻終りの端部を円錐形状の巻付け部材に巻付けることで巻線材を保持することができる。この結果、連続的にコイル部を形成することができる。
【００１２】
【発明の実施の形態】
本発明の実施の形態を添付図に基づいて以下に説明する。
図１は本発明に係る発電・電動機用ステータの組立治具で組立てるステータコアの平面図であり、図２は図１の２−２線断面図である。
ステータコア１０は、リング状のヨーク１１と、このヨーク１１から放射状に突出さた複数のティースＴ１〜Ｔ30と、ヨーク１１の内側に突出させた突起部１３・・・と、これらの突起部１３・・・の根本に形成した貫通孔１４・・・と、からなる。
また、ステータコア１０は、図２に示すように、複数枚のケイ素鋼板１５・・・を積層して形成した構造であることを示す。
【００１３】
図３は本発明に係る発電・電動機用ステータの組立治具で組立てる上インシュレータの平面図であり、図４は図３の４−４線断面図である。
上インシュレータ２０は、リング状の上本体部２１と、この上本体部から放射状に形成した複数の上ボビン部２２・・・と、上本体部２１に取付けた複数の接続端子Ｓ１〜Ｓ12と、上本体部２１に形成した上貫通孔２４・・・と、からなり、図４に示すように、上ボビン部２２・・・はティースＴ１〜Ｔ30（図１参照）のそれぞれ上半分を覆うように形成したことを示す。
【００１４】
図５は本発明に係る発電・電動機用ステータの組立治具で組立てる下インシュレータの平面図であり、図６は図５の６−６線断面図である。
下インシュレータ３０は、リング状の下本体部３１と、この下本体部から放射状に形成した複数の下ボビン部３２・・・と、下本体部に形成した下貫通孔３４・・・と、からなり、図６に示すように、下ボビン部３２・・・はティースＴ１〜Ｔ30（図１参照）の下半分を覆うように形成したことを示す。
【００１５】
図７は本発明に係る発電・電動機用ステータの組立治具の正面断面図である。
発電・電動機用ステータの組立治具４０（以下、「ステータ組立治具４０」と略記する）は、ステータコア１０を載置する基台４１と、この基台４１の中心に設けたセンタ支持台４２と、このセンタ支持台４２に取付けることで、ティースＴ１〜Ｔ30（図１参照）にコイル部Ｃ１（図９参照）等を形成するときに巻線材４４を巻付ける円錐形状の巻付け部材４５と、これらの基台４１、センタ支持台４２及び巻付け部材４５を一括して回転させる回転台４６と、からなる。
なお、４７はステータコア１０を基台４１に取付けるボルト、４８は巻付け部材４５をセンタ支持台４２に取付けるボルトを示す。
【００１６】
巻付け部材４５は、巻線材４４を巻付ける筒部５１と、この筒部５１から基台４１に向かって先細りテーパ形状に延出するとともにステータコア１０の上面１６レベルに設定することで、巻線材４４を巻付けたときに巻線材４４を筒部５１（図面下方）に誘導するテーパ部５２と、このテーパ部５２に巻線材４４を導くためのすり割り部５３と、センタ支持台４２に固定するためのボルト孔５４と、ボルト４８の頭部４９を沈める座ぐり部５５と、からなる。なお、１７はステータコア１０の下面を示す。
【００１７】
ステータ組立治具４０は、リング状のヨーク１１から放射状に複数のティースＴ１〜Ｔ30（図１参照）を突出させたステータコア１０に巻線を施すときに載置する発電・電動機用ステータの組立治具において、ステータコア１０を載置する基台４１と、この基台４１の中心に設けることでティースＴ１〜Ｔ30にコイル部Ｃ１（図９参照）等を形成するときに巻線材４４を巻付ける円錐形状の巻付け部材４５と、を備えたものであると言える。
【００１８】
一般的に、ステータコアは、リング状のヨークから放射状に複数のティースを突出させた形状を呈する。
そこで、ティースＴ１〜Ｔ30にコイル部Ｃ１（図９参照）等を形成するときに巻線材４４を巻付ける円錐形状の巻付け部材４５を設けた。例えば、巻線材４４の巻始めの端部若しくは巻終りの端部を円錐形状の巻付け部材４５に巻付けることで巻線材４４を保持することができる。この結果、連続的にコイル部Ｃ１（図９参照）等を形成することができる。
【００１９】
ステータ組立治具４０は、巻付け部材４５を、基台４１に向かって先細りテーパ形状にしたものとも言える。
巻付け部材４５を、基台４１にステータコア１０を載置したときに基台４１に向かって先細りテーパにすることで、巻線材４４を巻付け部材４５に巻付けたときに基台４１側に巻線材４４を移行させることができる。例えば、上インシュレータ２０にコイル部Ｃ１（図９参照）等の巻始めの端部若しくは巻終りの端部を接続する接続端子Ｓ１〜Ｓ12（図３参照）を設けておけば、これらの接続端子Ｓ１〜Ｓ12に自然に接触させることができ、接続端子Ｓ１〜Ｓ12へ巻線材４４の接続を容易にすることができる。
【００２０】
次に、図８〜図１５でステータコア１０に巻線コイルを施す手順を説明する。
図８〜図１５は本発明に係る発電・電動機用ステータの組立治具を用いてステータコアに巻線コイルを施す手順を示す説明図（その１〜８）である。
図８（ａ）において、ステータコア１０に上インシュレータ２０を矢印ａ１，ａ１の如く被せ、ステータコア１０に下インシュレータ３０を矢印ａ２，ａ２の如く被せる。
【００２１】
図８（ｂ）において、上・下インシュレータ２０，３０を取付け済みのステータコア１０をステータ組立治具４０に矢印ｂ１の如く載置し、このステータコア１０をボルト４７・・・でステータ組立治具４０に固定する。
【００２２】
図９（ａ）において、巻線材４４の巻始め端（巻始めの端部）６７をステータ組立治具４０の基台４１側に固定し、巻線材４４を巻付け部材４５のすり割り部５３に通す。なお、白抜き三角６１は、ステータコア１０のティースＴ１〜Ｔ30（図１参照）の巻線を施す巻線機を示す。
【００２３】
図９（ｂ）において、巻線材４４に所定のテンションを加えつつ、巻線材４４をテーパ部５２、筒部５１、接続端子Ｓ４を経由させティースＴ１に巻線を施し、このティースＴ１にコイル部Ｃ１を形成する。
例えば、巻付け部材４５に巻線材４４を巻付ける際に、図７に示す基台４１を回転（インデックス）させながら、巻線材４４を巻付け部材４５に巻付けるようにしたものであってもよい。ここで、インデックスとは所定位置まで回転させることを意味する。
【００２４】
図９（ｃ）において、巻線材４４に所定のテンションを加えつつ、ステータ組立治具４０を矢印ｃ１の如く回転させ、巻線機６１にティースＴ４を対面させるとともに、巻線材４４をステータコア１０の下面１７（図７参照）を這わせてティースＴ４まで導く。

【００２７】
図１１（ｂ）において、巻線材４４を接続端子Ｓ７を経由させて巻付け部材４５に戻し、巻線材４４に所定のテンションを加えつつ、ステータ組立治具４０を矢印ｂ３の如く回転させ、巻線機６１にティースＴ16を対面させる。
【００２８】
図７で説明したように、巻付け部材４５（図７参照）は、筒部５１から基台４１に向かってテーパ部５２を先細りテーパ形状に延出し、このテーパ部５２をステータコア１０の上面１６レベルに設定したものなので、巻線材４４を巻付け部材４５に巻付けたときに、巻線材４４を筒部５１（紙面裏方向）に自動的に誘導することができる。
図１１（ｃ）において、巻線材４４に所定のテンションを加えつつ、接続端子Ｓ10を経由させティースＴ16に巻線材４４を導く。
【００２９】
図１２（ａ）において、巻線材４４に所定のテンションを加えつつ、このティースＴ16にコイル部Ｃ16を形成する。
【００３０】
図１２（ｂ）において、巻線材４４に所定のテンションを加えつつ、ステータ組立治具４０を矢印ｂ４の如く回転させ、ティースＴ19に巻線を施すことでコイル部Ｃ19を形成し、ティースＴ22に巻線を施すことでコイル部Ｃ22を形成し、ティースＴ25に巻線を施すことでコイル部Ｃ25を連続的に形成し、巻線機６１にティースＴ28を対面させる。
図１２（ｃ）において、巻線材４４をステータコア１０の下面１７（図７参照）を這わせてティースＴ28まで導き、巻線材４４に所定のテンションを加えつつ、ティース28に巻線を施すことでコイル部Ｃ28を形成する。
【００３１】
図１３（ａ）において、ステータ組立治具４０を矢印ａ４の如く回転させ、巻線機６１にティースＴ２を対面させる。そして、巻線材４４に所定のテンションを加えつつ、巻線材４４を接続端子Ｓ１、巻付け部材４５、接続端子Ｓ５を経由させティースＴ２に導く。
【００３２】
図１３（ｂ）において、巻線材４４に所定のテンションを加えつつ、ティースＴ２に巻線を施す。
図１３（ｃ）において、図１０（ａ）〜図１２（ｃ）に示した手順で、ティース５，８，11，14，17，20，23，26，29に巻線を施す。
【００３３】
図１４（ａ）において、ステータ組立治具４０を矢印ａ５の如く回転させ、巻線機６１にティースＴ３を対面させる。
【００３４】
図１４（ｂ）において、図９（ｂ）〜図１２（ｃ）に示した手順で、ティース３，６，９，12，15，18，21，24，27，30に巻線を施し、接続端子Ｓ３を経由させて巻付け部材に巻線材４４を戻す。なお、６８は巻線材４４の巻終り端（巻終りの端部）を示す。
図１４（ｃ）において、接続端子Ｓ１〜Ｓ12に巻線材４４の経由させた部分を同時に接続する。
【００３５】
図１５（ａ）において、リング状のカッタ６５を用意し、このカッタ６５を矢印ａ６，ａ６の如く下降させることで、巻付け部材４５に巻付けた巻線材４４の巻付け部分６６・・・（１個のみ示す）を同時に切断する。
【００３６】
また、巻付け部材４５は、筒部５１から基台４１に向かってテーパ部５２を先細りテーパ形状に延出し、このテーパ部５２をステータコア１０の上面１６レベルに設定したものなので、巻線材４４を巻付け部材４５に巻付けたときに、巻線材４４の巻付け部分６６・・・を筒部５１に自動的に引き込むことができることを示す。
図１５（ｂ）において、ステータコア１０に巻線を施したステータ７０の完成した姿を示す。
【００３７】

【００４１】
ＳＴ０７：コイル部巻回工程

【００４２】
ＳＴ０８：巻線材戻し工程
巻線材４４を複数の接続端子Ｓ１〜Ｓ12の他の一つを経由させて巻付け部材に戻すことでコイル部（例えば、図１１に示すコイル部Ｃ１，Ｃ４，Ｃ７，Ｃ10，Ｃ13）を連続させた最初の系統の巻線コイル（例えば、図１１に示す巻線コイルＭ１）を完成させる。

実施の形態では図１６に示すように、ＳＴ０９に巻線コイル連続工程を設けたが、これに限るものではなく、巻線コイル連続工程は、１系統の巻線コイルのみを形成する場合には省略してもよい。
【００４８】
【発明の効果】
本発明は上記構成により次の効果を発揮する。
請求項１のように構成することで、複数の系統の巻線コイルを切らずに連続して巻くことができる。この結果、複数の系統の巻線コイルを巻回する作業時間の短縮を図ることができる。
【００４９】
また、前端部及び後端部を接続端子に同時に接続する接続端子接続工程を設けたので、複数の系統の巻線コイルの前端部及び後端部を接続端子に同時に接続することができ、接続時間の短縮を図ることができる。
さらに、前端部及び後端部を一括して切断する巻線材切断工程を設けたので、複数の系統の巻線コイルの前端部及び後端部を一括して切断することができ、切断に要する時間の短縮を図ることができる。
