Abstract: A rotor for a rotating electrical machine includes a cylindrical rotor core configured to be arranged radially inside of a stator with a coil wound therearound. An outer circumferential surface of the rotor core is opposed to the stator with a gap therebetween. The rotor core has a plurality of magnetic pole regions in a circumferential direction and also has, in each of the magnetic pole regions, a flux barrier extending along q-axis magnetic paths. An inner wall of the flux barrier has a radially outer wall surface and a radially inner wall surface. The radially inner wall surface is broadened to be closer to the adjacent magnetic pole region than a position along the q-axis magnetic paths.
