PURPOSE:To prevent the generation of a crack at the corner of a rotor and sharply improve the coupling force between the rotor barrel and axle sections and the coupling force between the rotor and a rotary shaft by arranging a cap- type stainless block provided with a thin iron plate on the external surface at the joint between the rotor barrel section and the rotary shaft. CONSTITUTION:A stainless block 9 whose external surface is covered with a thin iron cap 8 is cast and arranged on the inner wall surface at the rotor axle section 36 side of a cylindrical rotor barrel 3a made of Cu material, namely on the base of the rotor axle section 3b made of Mo material. In addition, a rotor 3 is tightened and fixed to a rotary shaft 4 by a screw 5 with intense coupling force through the stainless block 9 covered with the iron cap 8. |
