Kind Code:
A1
Abstract:
[Problem] To make it possible to highly accurately detect a rotation angle and to drive more safely. [Solution] Provided is an actuator (300) that is provided with: a reduction gear (320), which reduces, at a predetermined reduction ratio, a rotation speed of an input shaft connected to a rotation shaft of a motor (360), and which transmits the rotation speed to an output shaft (350); a first absolute angle encoder (330) that detects a rotation angle of the input shaft; and a second absolute angle encoder (340) that detects a rotation angle of the output shaft.
