Summary:The utility model relates to the field of mechanical technology, provides a permanent magnet servo motor rotor, and particularly to a fixing mode of dynamic balance paste of the permanent magnet servo motor rotor. The fixing mode comprises a rotating shaft, a rotor core is arranged at the outside surface of the rotor, magnetic steel is arranged at the outside surface of the rotor core, a jump ring is disposed at the end face of a joint of the rotor core and the rotating shaft, a stainless steel sleeve is arranged at the outside surface of the magnetic steel, an end of the stainless steel sleeve shows out of end faces of the magnetic steel and the rotor core to form a groove capable of containing dynamic balance paste. The fixing mode of the dynamic balance paste of the permanent magnet servo motor rotor is advantageous in that the dynamic balance paste can be directly put in the groove formed by the end faces of stainless steel sleeve and the magnetic steel, a whole structure of the rotor can be simplified and the weight of the rotor can be lightened, the rotational inertia of a motor rotor can be reduced, the responding speed of a whole motor system can be raised, the reliability of installation of the rotor core can be improved, and the cost can be reduced.
