Description
なお、炭化とは400℃以上で熱処理をしたものをいう。また、フィラーと結合剤との配合物にさらに炭素繊維や、二硫化モリブデン、二硫化タングステン等の固体潤滑剤を配合(添加)することによってさらに耐摩耗性の向上が図れる。
まず、端子部5と接触する接触部2の端面にニッケルめっきを施し、このニッケル面と端子部5とをはんだ付けする。端子部5は外周に爪部5aを有する円板状の銅製であり、接触部2はコークスを主成分とするフィラーと、結合剤とで構成され、この結合剤が、炭化されているものである。そして、端子部5に樹脂をモールドして支持部3を形成し、この支持部3に達するまで接触部2および端子部5を分割し、接触部62および端子部63を形成する。この後、爪部5aにコイルをヒュージングして接触部2とコイルとを電気的に接続する。

Claims (3)
- 少なくともブラシとの接触部が、コークスを主成分とするフィラーと、結合剤とを含んでいる整流子であって、前記結合剤が炭化されている整流子。
- 前記フィラーは、コークスが30重量%を超え80重量%以下で、残りが天然黒鉛、人造黒鉛または天然黒鉛及び人造黒鉛の混合物のいずれかである請求項1に記載の整流子。
- 電圧降下法により測定される整流子の加圧方向に直行する方向の抵抗率が、10μΩ・m以上、95μΩ・m以下である請求項1又は2に記載の整流子。
