Abstract
For providing an electric rotating machine, with which can be maintained the rotational symmetry of the stator iron or steel sheets, as well as the symmetry of the magnetic circuit, without increasing of the weight of the stator, wherein an electric rotating machine comprising: a stator having a stator core 101 being formed by fixing a laminated body of stator iron or steel sheets, and stator coils 102; a rotor 103 having a rotation shaft of; a frame 105 for receiving the stator therein; and end brackets 106 and 107 having through bolt holes 34 and outer attachment bolt holes 31, wherein the stator is fixed to the end brackets 106 and 107 by through bolts 14, and the electric rotating machine is installable onto an outside by means of outer attachment bolts, and the stator iron or steel sheet 1 is in a shape being symmetric both sides and upside down with axes B1-B4 and comprises a main body portion 11 and 15 and corner portions 12 in which are formed through bolt holes 13, the through bolt holes 13 are provided on the axes B1-B4 of symmetry and on a circumference around the rotation shaft O of the rotor at an equal distance between them, and further a line connecting between the t…
