The utility model discloses a rotor structure of a high-speed asynchronous motor, which comprises a rotating shaft, a rotor iron core at the body section of the rotating shaft, end rings at the two ends of the rotating shaft, squirrel cage strips and retaining rings, circumferential grooves distributed along the circumferential direction are arranged on the rotor iron core and the end rings, and each circumferential groove is an open groove from the groove bottom to the cylindrical surface. The circumferential grooves of the rotor iron core and the end ring are jointly provided with squirrel cage strips in a penetrating manner in the axial direction, the squirrel cage strips are fixed in the circumferential grooves in the radial direction, the protective ring is mounted on the outer circle of the end ring, the squirrel cage strips limit radial displacement through the structure of the rotor iron core, the squirrel cage strips and the end ring ensure good contact through pre-tightening elements, and the end pa
