Abstract:
An electric rotating machine comprising:a stator including a main body having a substantially constant width in a radial direction over an entire periphery thereof so as to function as a magnetic circuit, a stator core formed by accumulating and fixing a plurality of stator steel sheets, each of the stator steel sheets having corner portions formed with through bolt holes to be inserted with through bolts therein, and stator coils mounted onto said stator core; a rotor having a rotation shaft received within an inner periphery side of said stator; a frame for receiving said stator therein; and end brackets having through bolt holes and being fixed on both ends of said stator by through bolts inserted into the through bolt holes thereof, each of the end brackets having plural numbers of two kinds of bolt holes, one kind of the bolt holes corresponding to said through bolt holes formed on said stator steel sheet and the other kind of the bolt holes being for attaching said electric rotating machine outside, and for holding the rotation shaft of said rotor via bearings rotatably, wherein said frame is a molded frame with axes of symmetry extending between the rotation shaft of said rotor and said through bolt holes of said stator steel sheets and axes of symmetry extending between the bolt holes for attaching said electric rotating machine outside and said through bolt holes of said stator steel sheets are shifted by a predetermined angle.
