<P>PROBLEM TO BE SOLVED: To provide a rotor for rotary machine such that a bridge part is widened in width in a radial direction and leakage magnetic flux at the bridge part is reduced, and a method of manufacturing the same. <P>SOLUTION: A keyhole 6 is formed by heating and fusing at least a part of a bridge part 22, and a nonmagnetic element 81 is arranged at a periphery of the keyhole 6. Consequently, the bridge part 22 can be made nonmagnetic even when widened in width in a radial direction, and leakage magnetic flux at the bridge part 22 is reduced to make output of a rotary machine high. Further, the strength of the bridge part 22 can be increased by widening the radial width of the bridge part 22, and the bridge part 22 can be prevented from being broken owing to centrifugal force during high-speed rotation of a rotor 2. <P>COPYRIGHT: (C)2013,JPO&INPIT |
