SERVO MOTOR AND ROBOT DEVICE

WIPO Patent Application WO/2022/065289

A1

The present invention achieves an increase in design freedom and a size reduction. This servo motor is provided with: a driving unit including a rotor and a stator; an input shaft to which a driving force of the driving unit is transmitted and which is rotated integrally with the rotor; a reducer that reduces the rotating speed of the input shaft to provide an output; an output shaft to which the driving force transmitted to the input shaft is transmitted via the reducer; an input side encoder disc attached to the input shaft; an output side encoder disc attached to the output shaft; a circuit substrate on which a predetermined circuit pattern is formed; an input side sensor mounted on the circuit substrate in a state of facing the input side encoder disc; and an output side sensor mounted on the circuit substrate in a state of facing the output side encoder disc. At least one of the input side sensor and the output side sensor is mounted on the circuit substrate via a spacer substrate connected to the circuit substrate, and an electronic component different from the input side sensor and the output side sensor is mounted on the circuit substrate.
