The utility model discloses a rotor structure of large direct-drive wind power double-generator. The rotor structure comprises a rotor rack and a permanent magnet, wherein the rotor rack is cylindrical, the permanent magnet is fixed on the inner side of the cylindrical surface of the rotor rack, an external flange for mounting a flange is arranged at the outer end part of the cylindrical surface, and an internal flange equipped with a hub is arranged at the inner end part of the cylindrical surface of the rotor rack. In the utility model, the wind energy of the transmission system of the large direct-drive wind generator is transmitted to the hub through blades, and then transmitted to a wind generating set through the hub, compared with a conventional direct-drive wind power generation, the novel rotor structure has reduced transmission links, and less energy loss and components in the transmission process. As the rotor is mounted in the hub, the space is reasonably utilized, the structure is simplified, the
