An electric rotating machine having a stator including a stator core formed by accumulating and fixing a plurality of stator steel sheets, and stator coils mounted onto the stator core, a rotor having a rotation shaft received within an inner peripheral side of the stator, a molded resin frame for receiving the stator therein and a pair of end brackets for rotatably holding the rotation shaft of the rotor via bearings. A respective end bracket is fixed on opposite ends of the stator by through bolts inserted into through bolt holes formed therein, and each of the end brackets having a plurality of two kinds of bolt holes. Each of the stator steel sheets forming the stator core functions as a magnetic circuit, and corner portions thereof are formed with bolt holes in a semi-circular shape with an opening portion for receiving the through bolts.
