ROTOR AND ROTATING ELECTRIC MACHINE

WIPO Patent Application WO/2023/189909

A1

This rotor is rotatable about the central axis and comprises: a rotor core; and annular conductive parts arranged at axially opposite sides of the rotor core. The rotor core has a plurality of flux barrier groups arranged at intervals along the circumferential direction. The plurality of flux barrier groups each include a plurality of flux barriers arranged radially side by side, and the plurality of flux barriers each have a shape protruding radially inward as viewed in the axial direction. One or more flux barriers, of the plurality of flux barriers in each of the flux barrier groups, have disposed thereinside conductor bodies electrically connected to the annular conductive parts. As viewed in the axial direction, when the half of the outer diameter of the rotor core is defined as Ror, the half of the outer diameter of the annular conductive parts is defined as Roer, and the minimum distance from the central axis line to the radially outermost one of the flux barriers which have disposed thereinside the conductor bodies is defined as Rocb, the relation of Rocb
