ABSTRACT:
A rotor includes a rotor frame having a plurality of ribs which are disposed at predetermined intervals in a circumferential direction and which extend in a radial direction, and a shaft portion and a rim portion which are provided at inside diameter sides and outside diameter sides of the plurality of ribs, respectively, main magnet portions which are disposed individually between the ribs which are adjacent to each other in the circumferential direction, and a plurality of sub-magnet portions which are disposed on at least one sides of the ribs in the rotational axis direction, and wherein a rigid portion is formed in an area where the sub-magnet portions are projected in the radial direction relative to an area where the rib is projected in the radial direction in a cross section of the rim portion taken along the rotational axis direction.
