摘要
Core slots are provided in an outer circumferential side of a rotor core and extend in an axial direction of a rotor shaft. A rotor conductor is a rod-shaped conductor inserted in each of the slots, and after insertion of the rotor conductor in each slot, a flared portion is formed flaring in a slot-transverse direction, and a propping-apart force occurring between the flared portion and both side wall surfaces of the slot fixes the rotor conductor to the slot. In an inner wall of an outer circumferential side of each slot abutting the flared portion, an unevenness is arranged along the axial direction of the rotor shaft.
