Abstract

　電動機のロータボディ（３１）は、導電性材料製の第１、第２フランジ部材（３２，３３）の外周部と、周方向に所定間隔で配置した弱磁性体の導電性材料製の複数の連結部材（３４）の両端部とをボルト（３７）で連結し、周方向に隣接する連結部材（３４）間に軟磁性体製の誘導磁極（３９Ｌ，３９Ｒ）を支持して構成される。第１、第２フランジ部材（３２，３３）と連結部材（３４）との結合部を絶縁コーティングで電気的に絶縁したので、運転時に第１フランジ部材（３２）、連結部材（３４）、第２フランジ部材（３３）および連結部材（３４）で構成される閉回路を流れる渦電流を低減することができ、渦電流に伴う発熱やエネルギー損失を最小限に抑えることができる。
