Abstract
Description
また、コイル線のクロスポイントの位置を円周方向の全周に亘り順次ずらして、分散させるような構成にしている。(例えば特許文献2)
さらにまた、互いのクロスポイントがほぼ同じ位置で一方向に固まると、バランスが悪くなり、回転子として悪影響を生じさせる問題点があった。
また特許文献2では、クロスポイントを全周に形成しているがクロスポイントを円周方向手前にずらしていく必要があり、その場合、下層のコイルフィールドにコイル線の無い箇所が発生する。例えばこの下層のコイルフィールドの外周に、複数列で多段の山巻き部を巻回する場合、下層のコイルフィールドのクロスポイントは特許文献2にあるように8等分してあり、1/8周コイルの無い箇所が発生する。(特許文献2の、第2図の2層目のようなコイル線の無い部分が1/8周に発生する。)そのため特許文献2では山巻き部を含む上層のコイル線の落ち込みを防ぐためにクロスポイントをずらした層全ての層にテープ等を巻く必要があった。
第1および第2フランジ部が円筒状の巻胴部の軸方向の両端部から径方向の外周に延設された断面コ字状の環状に形成され、上記一対のポールコアの上記爪状磁極の根元部で挟持されて上記基部に装着されたボビンと、
コイル線を上記ボビンの巻胴部の外周に、軸方向に複数列で多段に巻回され径方向に隣接する段の上記コイル線により形成されるクロスポイントを有する下部のコイルフィールドと、この下部のコイルフィールドの外周と上記爪状磁極の内周との空き空間に配設され、上記下部のコイルフィールドの列数よりも少ない列数で複数段有する如く上記下部のコイルフィールドの外周に巻回され径方向に隣接する段の上記コイル線により形成されるクロスポイントを有する山巻きのコイルフィールドとからなる回転子コイルとを備え、
上記山巻きのコイルフィールドにおけるクロスポイントと、上記下部のコイルフィールドのクロスポイントとが、互いに円周方向にずれて配設されていることを特徴とする。
図1はこの発明の実施の形態1に係る回転電機の回転子の要部を示す断面図、図2はこの発明の実施の形態1に係る回転電機の回転子に適用されるボビンを示す斜視図、図3はこの発明の実施の形態1に係る回転電機の回転子における回転子コイルの巻装方法を説明する斜視図、図4乃至図6はそれぞれこの発明の実施の形態1に係る回転電機の回転子における回転子コイルの巻装方法を説明する工程図、図7は、この発明の実施の形態1に係る回転電機の回転子における回転子コイルの巻装状態を示す断面図、図8は、図7のVIII-VIII線断面図、図9は、この発明の実施の形態1に係る回転電機の回転子を示す斜視図である。
コイル線15は、断面円形の銅等の芯材の表面にポリイミド樹脂等の絶縁被膜を被覆して作製されている。このコイル線15は、ノズル23から繰り出され、その先端をスピンドル(図示せず)等に装着されたボビン16の係止部21aに巻き付け、溝22内を通って巻胴部17に導かれる。
また、コイルフィールドBは、コイルフィールドAの各段の列数より少ない列数で構成されているので、爪状磁極13との接触を避けてコイルフィールドAとポールコア12の爪状磁極13との間の空き空間に配設することができる。
また、コイルフィールドBにおいてもクロスポイントC4~5、C5~6、C6~7、C7~8は互いに円周方向に角度10度ずつずれて、径方向に関して重ならないように構成されている。しかも、クロスポイントC4~5とC1~2、クロスポイントC5~6とC2~3、クロスポイントC6~7とC3~4とは、各々円周方向に角度180度ずれて構成されている。
これに対し、この発明では、コイルフィールドBのクロスポイントをコイルフィールドAのクロスポイントと180度ずらすことで対称の形状となりバランスのよいコイルフィールドを得ることができるため、巻胴部17の厚みを変化させる必要がなくなる。その結果、コイル線15と爪状磁極13の内周壁面との接触を回避できるコイルフィールドAおよびBの段数を増やすことができるので、コイル線15の絶縁被膜の損傷の発生を抑制して、コイル線15の巻回数の多い回転電機が得られる。また、ボビン16の型も簡単になるため、バリ等の発生の抑えることができる。
なお、図1、図4、図5、図6ではコイルフィールドA部の奇数層と偶数層が同じ列数での説明をしているが、図10に示すように、奇数層の列数に対し偶数層の列数が1列少なくなる場合でも上記実施の形態1と同様の作用効果を奏するものである。
