Anti-vibration servo motor

The invention relates to the technical field of servo motors, in particular to an anti-vibration servo motor which comprises a motor body, a motor shaft penetrating through the motor body, an encoder installed on the motor body and a balance weight device arranged on the motor shaft in a sleeving mode, and the encoder is located between the motor body and the balance weight device. The centrifugal force generated when the motor main body drives the motor shaft is reduced by moving the mounting distance of the counterweight device on the motor shaft in a sleeving manner. The anti-vibration device has the advantages of being high in anti-vibration effect and good in stability. 本发明涉及伺服电机技术领域，更具体地说，它涉及一种避振伺服电机，包括电机主体、贯通所述电机主体的电机轴、安装于所述电机主体上的编码器以及套设于所述电机轴上的配重装置，所述编码器位于所述电机主体与所述配重装置之间，通过配重装置移动套设于所述电机轴上的安装距离，降低电机主体驱动电机轴产生的离心力。本发明具有避振效果强和稳定性好的优点。
