Abstract: A rotor includes a first rotor core, a second rotor core, a field magnet, and an auxiliary magnet. The first rotor core includes a first core base and a plurality of first hook-shaped poles. The second rotor core includes a second core base and a plurality of second hook-shaped poles. The first and second hook-shaped poles are alternately arranged in a circumferential direction of the rotor. The field magnet is arranged between the first and second core bases in an axial direction. The field magnet cause the first hook-shaped poles to function as first poles and the second hook-shaped poles to function as second poles. The auxiliary magnet includes at least two interpolar magnet portions, which are integrally formed. Each interpolar magnet portion is arranged in a void between the first hook-shaped pole and the second hook-shaped pole and magnetized in the circumferential direction.
