Abstract
A rotor for a rotating electrical machine includes pole faces arranged at locations on either side, respectively, of the rotor D-axis and fins arranged along the rotor Q-axis. The fins increase a section bending moment of inertia along the Q-axis, thereby reducing the need for deep slots in the pole faces extending along the D-axis, resulting in better symmetry of bending stiffness.
