摘要:
A rotor core includes a rotor core includes a plurality of rotor core blocks each of which is constituted by stacking annular sheet-like core materials in a direction of sheet thickness of each core material and a plurality of catch recesses circumferentially disposed in an inner circumference of each core material at an interval of a predetermined angle so as to extend radially outward, the catch recesses having respective circumferential dimensions equal to each other and different radial depths. In each rotor core block, a plurality of the core materials is stacked while the catch recesses having an identical configuration are aligned. The rotor core blocks have respective outer peripheries which are shifted from each other according to the depths of the catch recesses caught by a bar-shaped aligning jig when the catch recesses of the rotor core blocks are caught by the aligning jig.
