【００２５】
上記構成において、電動機の固定子を形成するときには、分割鉄心体１に絶縁物２を介し巻線３を巻装し、極数に応じて巻線巻装体５を形成するとき、一つの巻線巻装体５を形成したのち、次の巻線巻装体５に渡る渡り線４を絶縁物２に設けた突起８に巻き付けて保持し、順次巻線巻装体５を形成する毎に渡り線４を突起８に巻き付け巻線巻装体５を極数個形成し、巻線巻装体５を環状に配列する。
【００２６】
そして、巻線３の引出線６は引出ピン７に接続し、絶縁物２に設けられる薄肉溝１０のカット部１１の挿入口１０ａより、絶縁紙９の略Ｗ字状部９ｂを挿入し薄肉溝１０内に絶縁紙９を設け電動機の固定子を形成する。
【００２７】
このように本発明の実施例１の電動機の固定子によれば、分割鉄心体１に絶縁物２を介し巻線３を巻装し、極数に応じて設けられる巻線巻装体５と、巻線巻装体５を連設するように設けられる渡り線４と、渡り線４が係合されるように絶縁物２に設けられる突起８とを備え、突起８に渡り線４を巻き付けて保持するので、巻線巻装体５を環状に配列されるまでの間における渡り線４のたわみや巻線３のほどけを防止できる。
【００２８】
また、絶縁物２に主巻線３ａが巻装され極数個主巻線３ａの渡り線４ａを介して設けられる主巻線巻装体５ａと、絶縁物２を介し補助巻線３ｂが巻装され極数個補助巻線３ｂの渡り線４ｂを介して設けられる補助巻線巻装体５ｂと、絶縁物２の外側枠部２ｂに設けられる補助巻線３ｂの渡り線４ｂが巻き付けられる突起８と、絶縁物２の内側枠部２ａに設けられる主巻線３ａおよび補助巻線３ｂからの引出線６が接続される複数の引出ピン７とを備え、補助巻線３ｂの渡り線４ｂを外側枠部２ｂ近傍に、主巻線３ａの渡り線４ａを内側枠部２ａ近傍に区分けして配設したので、電位差のある主巻線３ａの渡り線４ａと補助巻線３ｂの渡り線４ｂとの接触するのが防止でき接触不良を防ぐことができる。
【００２９】
また、巻線巻装体５が環状に配列されるときに隣設する絶縁物２間に設けられる絶縁紙９と、絶縁紙９が挿入されるように絶縁物２に形成される薄肉溝１０と、薄肉溝１０の絶縁紙９の挿入口１０ａが拡がるようにカット部１１を形成したので、絶縁紙９の挿入が容易となる。
【００３０】
また、絶縁物２の薄肉溝１０に形成されるカット部１１に対応しないように渡り線４を配設したので、薄肉溝１０に挿入される絶縁紙９が渡り線４に当接するのが防止でき、渡り線４の損傷がなくなる。
【００３１】
また、長手方向の中心に折り目９ａを設けて断面をへの字状に形成した絶縁紙９の挿入側端部に略Ｗ字状部９ｂを形成したので、絶縁物２に形成された薄肉溝１０に対する絶縁紙９の挿入が容易となる。
【００３２】
（実施例２）
図４および図５に示すように絶縁物２Ａの薄肉溝１０Ａに形成されるカット部１１Ａの奥部に平坦部１２を形成した構成とする。
【００３３】
上記構成において、絶縁物２Ａの薄肉溝１０Ａに絶縁紙９を挿入するとき、絶縁紙９がカット部１１Ａより外れ挿入されると、絶縁紙９の先端部がカット部１１Ａに設けた平坦部１２に当接し、絶縁紙９を更に挿入しようとしても挿入できなくなり、カット部１１Ａ近傍に配設されていた渡り線４に絶縁紙９が当接することはない。
【００３４】
このように本発明の実施例２の電動機の固定子によれば、絶縁物２Ａの薄肉溝１０Ａに形成されるカット部１１Ａの奥部に平坦部１２を形成したので、図５に示すように絶縁紙９がカット部１１Ａより外れ挿入された場合においても絶縁紙９が渡り線４に当接することがなく、渡り線４の損傷が未然に防止できる。
