Abstract
Description
上記、従来の渡り部材を用いたステータのコイルの結線方法では、各渡り部材(特許文献1では18本)それぞれに対して、コイルの内周側端部と別のコイルの外周側端部との間に渡り部材を配置する作業を繰り返し行う必要がある。そのため、ステータのコイルを結線する作業に時間を要することになり、改善が望まれる。
本発明のステータ用配電部材は、ステータのコイルの両端部がステータの径方向の内周側と外周側とにそれぞれ位置する複数のコイルを結線するための部材である。そして、コイルの内周側端部に接続される平板状の第一接続端部と、別のコイルの外周側端部に接続される平板状の第二接続端部とを有する複数の導体片と、前記各導体片の両接続端部以外の箇所において、複数の導体片を離間した状態で一体に保持する絶縁保持部を複数具える。また、前記各絶縁保持部は、互いに離散的に配置されている。
本発明のステータ用配電部材は、次の工程により製造することができる。
1)コイルの内周側端部に接続される平板状の第一接続端部と、別のコイルの外周側端部に接続される平板状の第二接続端部とを有する複数の導体片を用意する工程
2)金型に前記各導体片を環状に配置する導体片配置工程
3)前記金型に樹脂を注入して、前記各導体片の両端接続部以外の箇所において、複数の導体片を離間した状態で一体に保持する絶縁保持部を複数形成する絶縁保持部形成工程
また、連結部を具える場合は、絶縁保持部形成工程において、各絶縁保持部とこれら絶縁保持部を環状に連結する連結部とを一体成形することが好ましい。
本発明のステータ用配電部材の取り付け構造としては、ステータのコイルの両端部が平板状であり、導体片の各接続端部が各コイルの端部に溶接にて接続されている構造が挙げられる。
図9Aは、中性点用導体片15の変形例を示す正面図であり、形状が上述の中性点用導体片と異なり、コイルの端部に接続される各接続部151~153が幅方向に突出していない。このような中性点用導体片15は、例えば平角銅線を曲げ加工することで作製できるため、銅板を打ち抜きすることなく得ることができ、材料のロスが少なく歩留まりを向上させることができる。さらに、各接続部のうち、中央に位置する接続部152の両側には切欠部15cが設けられている。接続部152の両側に切欠部15cを設けることで、接続部152とコイルの端部とを溶接により接合する際の溶接熱が中性点用導体片15の両端部側に伝導することを抑制して、溶接熱を局所的に加えることができるので、溶接作業が行い易くなる。なお、切欠部15cは、平角銅線の外縁部を切削や切除することで形成すればよい。
