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.

Abstract: An induction machine includes: a stator having a stator core and a coil; a rotor, which has a shaft, a rotor core secured to the shaft, and a secondary conductor; a bearing supporting the shaft; a cooling fan having a blade; and a cooling fan fixture. The secondary conductor includes a rotor bar and an end ring. The blade is located axially outward of the end ring, and the distal end of the blade in the axial direction extends axially outward of the coil end of the coil. The cooling fan has a securing portion located radially inward of the end ring and a cylindrical extended portion extending from the securing portion to the blade. The securing portion is secured to the rotor with the cooling fan fixture. The bearing is located axially inward of the distal end of the blade.
