Abstract

　ブラシレスＤＣサーボモータ（１）の中空モータ軸（４１）の軸端部（４１３）には、工具ホルダープレート（５１）が固定され、ここに形成した工具取り付け孔（５１ａ）に切削工具を取り付けてワークの切削加工が行われる。中空モータ軸（４１）の軸端部（４１１）とモータハウジング（２）の端板部分（２２）の間からモータ内部に切削粉を含む切削加工油が侵入することを防止するために、金属プレート（５３）、工具ホルダープレート（５１）、軸端部（４１１）の間に、軸線方向（１ａ）に延びる二重の微細幅の円形溝（５５３、５５５）を含むラビリンスシール（５５）が形成されている。他方の軸端部（４１４）にも同様な構造のラビリンスシール（５６）が形成されている。モータ内部への切削加工油の侵入を防止でき、切削加工油に含まれる切削粉がオイルシール（４８、４９）に付着してこれらが早期破損する等の不具合を回避できる。
