Abstract
An electric rotating machine includes a stator with a stator core formed of a plurality of stator steel sheets with corner portions having through bolt holes for receiving through bolts therein, and a rotor. A frame receives the stator with end brackets being fixed on ends of the stator by through bolts inserted into the through bolt holes thereof. Each of the end brackets includes bolt holes corresponding to the through bolt holes formed on the stator steel sheets and bolt holes for at least attaching the electric rotating machine outside. The frame is molded so that axes of symmetry extending between a rotation shaft of the rotor and the through bolt holes of the stator steel sheets and axes of symmetry extending between the bolt holes for attaching the electric rotating machine outside and the through bolt holes of the stator steel sheets are shifted by a predetermined angle.
