Abstract:
Provided is a two-axis driving electromagnetic actuator that includes a stage that is operative to be actuated about a first axis; an inner frame that that is disposed outside the stage and supports the stage by the first axis; an external frame that is disposed outside the inner frame and supports the inner frame by a second axis which is perpendicular to the first axis; a magnet that provides an electric field between the first axis and the second axis; a first driving coil that is formed on the inner frame and to which a first signal that actuates the stage in a direction of the second axis is applied; and a second driving coil that is formed on the inner frame and to which a second signal that actuates the stage and the inner frame in a direction of the first axis is applied, wherein the first driving coil and the second driving coil are electrically separated from each other.
