PROBLEM TO BE SOLVED: To provide a rotor capable of keeping a bond strength of a rotor core while stabilizing a weld quality in an end of the rotor core.SOLUTION: In a rotor 20, a rotor core 21 includes: a core welding part 25 which is provided on an inner peripheral surface 21f of the rotor core 21 so as to extend in an axial direction and in which a plurality of electromagnetic steel sheets 22 are welded with each other in the axial direction; and a welding suppression part 26 which is provided from an end 25a (25b) of a core welding part 25 in the axial direction to a core end face 21c (21d) of the rotor core 21 in the axial direction and in which welding is suppressed more than the core welding part 25. A weld depth d3 of a hub member welding part 29 from the core end face 21c (21d) in the axial direction is equal to or more than a length L2 of the welding suppression part 26 from the core end face 21c (21d) in the axial direction.SELECTED DRAWING: Figure 1 |
