Description

【0001】
【産業上の利用分野】
帯状の固定子コアの所定のティースにコイルを巻回し、このコイルの巻終わりをバックヨークに沿って渡り線を配線して次のティースにコイルを巻回して帯状の固定子を形成した後、この固定子を折り曲げて形成された筒状の固定子に関する。
【0002】
【従来の技術】
従来におけるコイルの成形方法、およびコイルの渡り線の処理方法を図4および図5を用いて説明する。図4は、従来におけるコイルの成形方法を説明した固定子の正面図である。図5は、従来におけるコイルの渡り線の処理方法を説明した固定子の正面図である。
【0003】
図4において、固定子コア11は、帯状に形成されたバックヨーク12と、このバックヨーク12の一方の側面から延出した複数個のティース13とで構成されている。
【0004】
また、固定子14は、この固定子コア11のそれぞれのティース13に巻回されたコイル15と、このコイル15と固定子コア11の間に設けられ、コイル15と固定子コア11の絶縁を行うための絶縁物16とで構成されている。
【0005】
この絶縁物16は、固定子コア11のバックヨーク12の端面部にも延出して設けられており、また、後述するコイル15の渡り線15aを収納する溝16aが絶縁物16の外周面に設けられている。
【0006】
そして、それぞれのコイル15をティース13に巻回す巻線方法として、まず、コイル15の一方の先端(コイルの巻始め)を任意の箇所に固定して、巻線機17により、コイル15を所定のティース13に巻回す。そして、このティース13にコイル15を巻終えると、巻終わったコイル15の端末(コイルの巻終わり)を把持しながら、巻線機17は、次にコイル15が巻回されるティース13に移動して、このティース13にコイル15を巻回す。このとき、コイル15の渡り線15aを絶縁物16の溝16a収納して、この溝16aをガイドに、巻線機17を移動させるようにする。
【0007】
【発明が解決しようとする課題】
図5において、前述したように、コイル15の渡り線15aを溝16aを収納した後、固定子14を折り曲げて、筒状の固定子を形成する際に、固定子の径差により渡り線15aにたるみが生じてしまう。このたるみにより、渡り線15aが、溝16aから外に外れると断線あるいはレヤーの危険性がある。
【0008】
【課題を解決するための手段】
本発明によれば、帯状に形成され、略ストレート状のバックヨークと、このバックヨークより一方向に突出した複数個のティースと、ティース間に形成された複数のVカット溝とからなる固定子コアと、この固定子コアのバックヨークおよびティースに形成された絶縁物と、この絶縁物で絶縁されたティース部に巻き回わされた巻線とからなり、巻線後に前記固定子コアを巻き曲げて筒状に形成した固定子において、前記固定子コアのバックヨークに形成された前記絶縁物に渡り線収納用の複数本の溝を外周方向に平行に形成し、かつ、この複数本の溝は、帯状の固定子を巻き曲げて筒状に形成しても渡り線がはみ出さない深さに形成し複数の渡り線を複数本の溝に、直線状で、かつ、他相の渡り線と平行に配したことを特徴とする固定子を提供する。
【0009】
あるいは、前記絶縁物の溝の底の形状を凹凸状に形成し、この凹凸状の底の面に沿うように前記コイルの渡り線を押しつけて、このコイルの渡り線を絶縁物の溝の底に固定したことを特徴とする固定子を提供する。
【0010】
【作用】
まず、所定のティースに巻回されたコイルの巻終わりを、絶縁物の溝に収納させながら、次に巻回すティースに移動させる。また、絶縁物の外周径は、すべてのティースにコイルを巻回して構成された固定子を折り曲げて筒状にした後、コイルの渡り線のたるみが、溝からはみ出さない外周径にする。
【0011】
また、絶縁物の溝の底を凹凸形状にして、溝の底の沿面距離を長くし、この絶縁物の溝の底に渡り線を押しつけることにより、渡り線のたるみを溝の底に吸収させる。
【0012】
【実施例】
本発明による実施例を図1〜図3を用いて説明する。図1は、本発明における帯状の固定子の正面図である。図2は、図1の固定子の部分側断面図である。図3は、図1の固定子を折り曲げて形成した固定子の正面図である。
【0013】
図1および図2において、固定子コア1は、従来例で述べた固定子コアと同様に、帯状のバックヨーク2と、このバックヨーク2の一方の側面より延出した複数個のティース3とで構成されている。また、固定子4は、固定子コア1と、固定子コア1のティース3に巻回されたコイル5と、絶縁物6とで構成されている。そして、この固定子4を折り曲げて、筒状の固定子4を形成する。
【0014】
絶縁物6は、固定子コア1とコイル5との間に設けられ、電気的絶縁を行うため、および、コイル5の渡り線5aを収納し、この渡り線5aの断線防止などを行うために設けられている。
【0015】
渡り線5aの断線防止用に設けられた絶縁物6は、固定子コア1のバックヨーク2の端面上に設けられ、断線防止用の絶縁物6の外周面には、複数個の溝6aが設けられている。また、絶縁物6の外周径は、すべてのティース3にコイル5を巻回して構成された固定子4を折り曲げて筒状にした後、コイル5の渡り線5aのたるみが、溝6aからはみ出さない程度の外周径にする。
【0016】
そして、従来例と同様に、巻線機(図示しない)により、コイル5を所定のティース3に巻回す。そして、このティース3にコイル5を巻終えると、巻線機は、巻終わったコイル5の端末を把持しながら、次にコイル5が巻回されるティース3に移動して、このティース3にコイル5を巻回す。このとき、コイル5の渡り線5aを絶縁物6の溝6a収納して、この溝6aをガイドに、巻線機を移動させるようにする。
【0017】
そして、コイル5の渡り線5aを溝6aを収納した後、固定子4を折り曲げて、筒状の固定子を形成する際に、固定子4の径差により渡り線5aにたるみが生じても、渡り線5aが溝6aから外れることはない。
【0018】
図3において、絶縁物7に設けられている溝7aの底の形状が、凹凸形状に形成されている。溝7aの底の形状を凹凸形状にすることにより、溝7aの底の沿面距離を長くすることができる。つまり、この溝7aの底にコイル8の渡り線8aを固定子9の外周面側から押しつけて、渡り線8aを溝7aの底の凹凸に沿わせて渡り線8aも凹凸形状にすることにより、渡り線8aのたるみを吸収させることができ、さらに、渡り線8aは、溝の底に固定され、渡り線8aに多少の外圧が加わっても溝7aの外へ外れる危険性が少なくなる。
【0019】
【発明の効果】
本発明によれば、固定子コアの端面を渡る渡り線のたるみを防止し、渡り線のたるみによる断線、レヤーなどの不具合を減少させることができる。
