  • Patent number: 10637331
    Abstract: A servo (1) includes a power input device (14), a gear assembly (15) drive-connected to the power input device (14), a power output frame (13) that is driven to rotate by the gear assembly (15), an output shaft (131) arranged at the power output frame (13), a magnetic encoding assembly (121) that is arranged at a rotation center axis of the power output frame (13) and used to detect a rotation angle of the output shaft (131) relative to the rotation center axis, and a circuit board (12) connected to the magnetic encoding assembly (121) and the power input device (14). The magnetic encoding assembly (121) does not tend to be affected by environment, to accurately detect the rotation angle of the output shaft (131) relative to the rotation center axis. Meanwhile, the magnetic encoding assembly (121) is simple to structure and light in weight, which facilitates it to be fixed to the servo (1).
