【発明の属する技術分野】
本発明は継鉄部と歯部とが一体でスロット数と同数に分割した分割鉄芯体を用いたコンデンサ電動機の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２０００−２５３６０３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１４〜図１６を参照しながら説明する。
【０００４】
図１４、図１５および図１６に示すように、主巻線１０１は環状に保持された極数個の分割鉄芯体１０２の各々に絶縁体１０３を装着後に主渡り線側の渡り線１０４Ａを介して連続的に巻回されて主巻線巻装体１０５が形成され、同様に補助巻線１０６も環状に保持された極数個の分割鉄芯体１０２の各々に絶縁体１０３を装着後に補助渡り線側の渡り線１０４Ｂを介して連続的に巻回されて補助巻線巻装体１０７が形成され、前記主巻線巻装体１０５と補助巻線巻装体１０７を軸方向に移動させ組立し固定子１０８を構成していた。
【０００５】
【発明が解決しようとする課題】
このような従来の固定子１０８における巻線巻装方法および構成では、装着した絶縁体１０３に渡り線１０４Ａ、１０４Ｂには保持機構分がないため、渡り線１０４Ａ、１０４Ｂの保持は巻線機の構造部分にその機能を持たせる必要があり、巻線機の構造が複雑になるという課題があった。また、主巻線巻装体１０５と補助巻線巻装体１０７を軸方向に組み合わせるとき前記渡り線１０４Ａ、１０４Ｂの処理が複雑になるという課題があった。
【０００６】
本発明は上記課題を解決するもので、巻線機の構造部分を簡略化し、主巻線巻装体と補助巻線巻装体の組み合わせ時の取り扱いが容易となり、組み合わせ作業の簡略化を図ることのできるコンデンサ電動機の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。
【０００７】
【課題を解決するための手段】
本発明のコンデンサ電動機の固定子およびそ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有した歯部とからなる分割鉄芯板を所定枚数積層固着してスロット数と同数に分割してなる分割鉄芯体を形成し、前記分割鉄芯体に絶縁物を装着した上に集中巻で渡り線を介し主巻線を極数個連続的に直巻巻装した主巻線巻装体と、前記分割鉄芯体に絶縁物を装着した上に集中巻で渡り線を介し補助巻線を極数個連続的に直巻巻装した補助巻線巻装体とよりなり、前記極数個の主巻線巻装体を環状に配列した主巻線巻装体配列群と、前記極数個の補助巻線巻装体を環状に配列した補助巻線巻装体配列群とを、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組み合わせ固着一体化してなる固定子において、前記主巻線巻装体配列群は、極数個の前記分割鉄芯体それぞれに絶縁物を装着して環状に配列し、絶縁性の材料からなる環状の連結部を歯部内周側であって回転軸方向の頂部（あるいは底部）に装着して一体化した上で、前記連結部の外周側に沿って設けた渡り線を介し主巻線を極数個連続的に直巻巻装したものであり、
前記補助巻線巻装体配列群は、極数個の前記分割鉄芯体それぞれに絶縁物を装着して環状に配列し、絶縁性の材料からなる環状の連結部を歯部内周側であって回転軸方向の底部（あるいは頂部）に装着して一体化した上で、前記連結部の外周側に沿って設けた渡り線を介し補助巻線を極数個連続的に直巻巻装したものであり、前記主巻線巻装体配列群の渡り線を設けない側と補助巻線巻装体配列群の渡り線を設けない側とを対向させて軸方向に組み合わせた構成としたものである。
【０００８】
本発明によれば、分割鉄芯体に主巻線および補助巻線を直巻巻装する巻線機の構造部分の簡略化と巻線巻装作業の容易化、そして主巻線巻装体と補助巻線巻装体を組み合わせる組立工程におけるこれらの取り扱いが容易となり、作業の簡略化を図ることのできるコンデンサ電動機の固定子およびその製造方法を提供することができる。
