The permanent magnet motor comprises a novel permanent magnet motor rotor, and the novel permanent magnet motor rotor comprises a rotor iron core, an injection molding material and magnetic steel. Wherein the rotor core is provided with a through hole along the axial direction of the rotor core, the injection molding material is arranged in the through hole, an assembly hole is formed between the injection molding material and the inner wall of the through hole, the magnetic steel is arranged in the assembly hole, and the magnetic steel is in interference fit with the assembly hole under the limit of the injection molding material, so that the magnetic steel is limited in the assembly hole. Compared with the prior art, the magnetic steel is directly inserted into the assembly hole, and the assembly process is simple and convenient; in the magnetic steel assembling process, an injection molding process is not needed, so that the magnetic steel does not need to be influenced by high temperature and high pressur
