A servo motor encoder, comprising a rotating shaft, an encoder component, a cushioning and shock absorbing connecting piece configured to achieve cushioning and shock absorbing, and a cushioning and shock absorbing connecting piece mount configured to mount the cushioning and shock absorbing connecting piece. One end of the cushioning and shock absorbing connecting piece is connected to a servo motor, the other end of the cushioning and shock absorbing connecting piece is connected to the rotating shaft, the rotating shaft is sleeved in the cushioning and shock absorbing connecting piece mount, and the encoder component is mounted on the end surface of the cushioning and shock absorbing connecting piece mount relatively away from a cross-shaped connecting shaft component.
