PROBLEM TO BE SOLVED: To provide a rotor, rotary machine and manufacturing method for rotor, suitable for high-speed rotation.SOLUTION: A rotor 10 includes: a cylindrical sleeve 13; a permanent magnet 12 with a sleeve 13 subjected to shrink fitting. The permanent magnet 12 includes: a plurality of first permanent magnet segment 12 N and a plurality of second permanent magnet segment 12 S whose magnetic poles are different from each other in the radial direction. The plurality of first permanent magnet segment 12 N and the plurality of second permanent magnet segment 12 S are alternately arranged in the peripheral direction and employs means that has a positional relationship of a point symmetry with a rotational center C centered.SELECTED DRAWING: Figure 2 |
