Zusammenfassung:Disclosed is a rotor for a rotating electrical machine, comprising a rotor core in which a first magnet hole on the outside in the radial direction and a second magnet hole on the inside in the radial direction are formed, a first permanent magnet in the first magnet hole, and a second permanent magnet in the second magnet hole, the rotor core includes a first portion located radially outward of the first magnet hole, a second portion between the first magnet hole and the second magnet hole, a third portion radially inward of the second magnet hole, and a bridge portion connecting the third portion and the second portion, and the rotor core extends along a side of the second permanent magnet facing the first permanent magnet when viewed in the axial direction. The distance at which the second permanent magnets are separated from the first permanent magnets is smaller at a position closer to the bridge portions in the circumferential direction than at a position farther from the bridge portions in the circumfe
