ROTARY ACTUATOR AND CONTROL METHOD OF THE SAME

摘要

PROBLEM TO BE SOLVED: To simplify a circuit structure of a control part of a rotary actuator.SOLUTION: A rotary actuator 100 includes: a movable electrode 120; a frame 110; a holding member 130; a fixed electrode 140; and a control part 200. The holding member 130 attaches the movable electrode 120 to the frame 110 and serves as a rotation shaft of the movable electrode 120. The fixed electrode 140 faces the movable electrode 120 in a plane view. The control part 200 applies a voltage, which is generated by superposing an alternating current voltage on a direct current voltage, to an area between the fixed electrode 140 and the movable electrode 120. Then, the control part 200 controls the direct current voltage thereby controlling an angle of the movable electrode 120.
