Title:
ROTARY ACTUATOR
Document Type and Number:
WIPO Patent Application WO/2022/030451
Kind Code:
A1
Abstract:
These rotary actuators (40, 800, 900) each include a motor (50), gears (51-54, 60, 74, 810, 820, 830, 840, 850, 910, 920), a detected part (65), and an absolute angle sensor (68). The gears constitute an N-stage (N is an integer of 2 or more) deceleration stage that transmits the rotation of the motor (50) to an output shaft (15). The detected part (65) is provided in one of the gears. The absolute angle sensor (68) detects a physical quantity that changes due to the rotation of the gears (53, 840) to be detected which are gears provided with the detected part (65). The gears (53, 840) to be detected are located on the motor (50) side from a final deceleration stage, and a rotation range is within a range in which an absolute angle can be detected by the absolute angle sensor (68).
