PURPOSE:To prevent an out-of plane deformation of yoke, by a method wherein sections confronting to pole clamping plates for layer built sections are formed with material of high rigidity. CONSTITUTION:A pole 1 is connected to a yoke 2a via a fitting section and is firmly fixed via a cotter and/or a liner. The pole 1 is organized with layer built sheets, and the both end faces are supported by pole clamping plates 6 which are thicker than the sheets. The sections confronting to the pole clamping plates 6 for layer built sections are provided with members 8 which are more rigid than a single plate 7 the component of the yoke 2. As the result, the sections confronting to the pole clamping plates 6 for the layer built sections get more rigid, and the layer built yoke 2a of a rotor for a rotary electric machine can be obtained so that the out-of plane deformation of the yoke may be prevented. |
