A rotor for electrical machine

A rotor (10) for a rotating electrical machine has a plurality of magnetic poles (24), which are arranged circumferentially at intervals on the outer periphery of a rotor core (12). Each of the magnetic poles (24) includes a first permanent magnet (26) which is buried in the center of the magnetic pole, and a pair of second permanent magnets (28) that are buried on either side of the first permanent magnet (26), based on the circumferential direction, and which are arranged so that a mutual distance between the two second permanent magnets (28) inwardly less in the radial direction. A minimum distance between the two second permanent magnets (28) is arranged such that it is greater than a longitudinal width of the first permanent magnet (26) in a Kraftlinienwegregion (30) from the first permanent magnet (26) and the two second permanent magnets (28) is defined.
