The invention discloses a kind of rotor structure for permanent magnet motor for enhancing harmonic field shielding action, including shaft, which is characterized in that the surface of the shaft is successively enclosed with rotor core, permanent magnet, shielded layer and rotor jacket from inside to outside；The axial ends of the permanent magnet is equipped with conductive end cap, and the conductive end cap is fixedly linked with shielded layer, and is close to permanent magnet.The structure can effectively reduce the eddy-current loss in the intracorporal eddy-current loss of permanent magnetism and shielded layer, and reduce total eddy-current loss of rotor, improve the operational reliability of magneto. |
