PROBLEM TO BE SOLVED: To provide a rotator which makes a coaxial degree for inner and outer diameters of a rotor accurate and is capable of setting an air gap to a minimum, and a rotary machine.SOLUTION: In a rotator 106, a split core 1 is split on the basis of (k) poles as the number of poles of permanent magnets 3 accommodated in outer diameter side magnet housing parts 3c and inner diameter side magnet housing parts 3d (magnet housing parts) of a rotator core 9. The rotator core 9 includes (n) pieces (n≥k) of through-holes which are provided as many as or more than the number of poles of the rotator core 9 and through which rivets 2 (members for fixture) are passed in a direction of lamination. Between the split cores 1 which are neighboring to each other in a circumferential direction, a gap is provided that is set larger than a clearance CL. The split cores 1 (annular bodies) are laminated in the direction of lamination according to a jig which maintains the coaxial degree relatively to a reference axis by the gap or the clearance CL while being deviated in the circumferential direction by an integer multiple of one pole of the rotator core 9, and fixed to a disk 4 (fixed member) by the rivet 2. The accuracy for the coaxial degree of the rotator core 9 is also improved.SELECTED DRAWING: Figure 11 |
