Abstract
Disclosed are a rotor and a permanent magnet motor. The rotor includes a rotor core, at least two first permanent magnets and at least two second permanent magnets. A coercivity of each first permanent magnet is different from a coercivity of each second permanent magnet, the at least two first permanent magnets and the at least two second permanent magnets are arranged in an axial direction in magnetic steel slots of the rotor core. One of the first permanent magnets and one of the second permanent magnets are arranged to be connected in series in a radial direction of the rotor core in one slot to form a permanent magnet pole. A consequent pole is formed between every two adjacent permanent magnet poles, and the permanent magnet pole forms a magnetic circuit passing through the consequent pole.
