Abstract
A rotor includes: cylindrical rotor core blocks fixed to the rotary axis to be adjacent in an axial direction, the rotor core blocks including insertion portions disposed at intervals in an end surface in the axial direction so as to extend in the axial direction, and slots disposed at intervals in a circumferential direction so as to extend in the axial direction, the insertion portions of adjacent rotor core blocks facing each other and being successive to each other, and the slots facing each other and being successively each other; fixing pins having elasticity in an orthogonal planar direction orthogonal to the axial direction, the fixing pins being inserted to the insertion portions facing each other in the axial direction to fix the rotor core blocks to be adjacent in an axial direction; and magnets disposed in the slots to extend across the rotor core blocks.
