Abstract
A plurality of auxiliary magnets is embedded in a rotor core so as to surround the rotation axis of the rotating electrical machine in the cross-section orthogonal to the rotation axis. A plurality of main magnets is embedded in the rotor core so as to extend from the auxiliary magnet in the outer circumferential direction of the rotor. A plurality of magnetic poles of the rotor is formed around the rotation axis, the magnetic poles each having the auxiliary magnet and the plurality of main magnets arranged at a distance from each other in the circumferential direction of the rotor, and the plurality of main magnets of each magnetic pole is arranged asymmetrically about a virtual line passing the rotation axis and axisymmetrically dividing the auxiliary magnet of each magnetic pole.
