A permanent magnet synchronous machine (1) includes a rotor (11) including a core body (3) and an overhang (10) protruding further in an axial direction than a core (2) of a stator (100). An end surface (235a) of the core body (3) includes an N-region disposed on a north pole and an S-region disposed on a south pole. The overhang (10) includes first permanent magnets (5) arranged along an outer edge of the end surface (235a) with distances therebetween and a plurality of second permanent magnets (6) disposed on the end surface (235a) and adjacent to the first permanent magnets (5). The first permanent magnets (5) include at least one of a permanent magnet comprising a north pole facing the N-region and a permanent magnet comprising a south pole facing the S-region. The second permanent magnets (6) are provided in the configuration which causes the second permanent magnets (6) to generate a magnetic flux extending from the S-region toward the N-region.
