Abstract
A servo includes a housing, and a motor, a reduction gear drive mechanism, an output shaft, a position sensor and at least two stages of transmission gear. The reduction gear drive mechanism is connected with motor and the output shalt of the servo, the reduction gear drive mechanism used to transmit power from the motor to the output shaft of the servo. A head stage of the transmission gear is located on a tail end of the output shaft of the servo, and the position sensor is located at an axis of a tail stage of the transmission gear. The at least two stages of transmission gear transmit a rotation angle of the output shaft of the servo to the position sensor by a ratio of 1:1, the position sensor is not arranged coaxially with the output shaft of the servo.
