A rotor is provided, and is used in a permanent-magnet motor. The rotor includes a rotating shaft (111) and a rotor iron core (112) sleeved on the rotating shaft (111). The rotor further includes several first permanent-magnet structures (14), the several first permanent-magnet structures (14) are distributed on the rotor iron core (112) in a circumferential direction of the rotor iron core (112), each first permanent-magnet structure (14) includes a first permanent magnet (141) and a second permanent magnet (142) that are disposed in a radial direction of the rotor iron core (112), and coercive force of the first permanent magnet (141) is less than coercive force of the second permanent magnet (142).
