摘要：
A rotor for a rotating electric machine comprises a rotor core, and a plurality of rotor conductors wound on the rotor core. At least one of the rotor conductors is provided with a cooling groove, and edges of at least one of the cooling grooves are rounded by a radius process to reduce peak stresses that may be induced around the edges of the cooling groove.
