Rotating electrical machine

A rotating electrical machine comprising:

• a rotor with permanent magnets embedded in a rotor core made of a soft magnetic material;
• and
• a stator positioned on an outer circumference of the rotor,
• wherein:
• the permanent magnets include a main magnet arranged so as to be magnetized in a circumferential direction of the rotor, and an auxiliary magnet arranged so as to be magnetized in a radial direction of the rotor,
• the auxiliary magnet includes a plurality of auxiliary magnets, the plurality of auxiliary magnets being embedded in the rotor core so as to surround a rotation axis of the rotor in a cross-section orthogonal to the rotation axis,
• the main magnet includes a plurality of main magnets, the plurality of main magnets being embedded in the rotor core so as to extend from the auxiliary magnets in an 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, the soft magnetic material being disposed between the main magnets, and
• in the cross-section orthogonal to the rotation axis, the main magnets of each magnetic pole are arranged such that the plurality of main magnets are arranged asymmetrically about a virtual line passing the rotation axis and axisymmetrically dividing the auxiliary magnet of each magnetic pole.
