Abstract
An electrostatic drive having at least three intermediate frames, each two adjacent intermediate frames being connected to one another via at least one intermediate spring whose longitudinal directions lie on a first axis of rotation, and intermediate electrode fingers being situated on frame girders oriented parallel to the first axis of rotation of the intermediate frames, and having an outer frame that surrounds the intermediate frames and that is connected to the outermost intermediate frame via at least one outer spring whose longitudinal direction lies on a second axis of rotation that is oriented non-parallel to the first axis of rotation, and outer electrode fingers being situated on frame girders oriented parallel to the second axis of rotation of the outer frame and of the outermost intermediate frame of the at least three intermediate frames. In addition, a micromechanical component having this electrostatic drive, a method for operating such a micromechanical component, and methods for manufacturing the electrostatic drive and the micromechanical component are described.
