Patent ID: 8188634

Claim:
An electrostatic drive, comprising: at least three intermediate frames including at least one first intermediate frame, a second intermediate frame that surrounds the first intermediate frame, and a third intermediate frame that surrounds the first intermediate frame and the second intermediate frame; at least two intermediate springs, each two adjacent intermediate frames of the at least three intermediate frames being connected to one another via at least one of the intermediate springs, the at least two intermediate springs being situated such that longitudinal directions of the intermediate springs lie on a first axis of rotation; intermediate electrode fingers situated on frame girders, the frame girders being oriented parallel to a first axis of rotation of the at least three intermediate frames; an outer frame that surrounds the at least three intermediate frames and that is connected via at least one outer spring to an outermost intermediate frame of the at least three intermediate frames, the at least one outer spring being situated such that a longitudinal direction of the at least one outer spring lies on a second axis of rotation that is oriented non-parallel to the first axis of rotation, and outer electrode fingers of the outer frame and of the outermost intermediate frame situated on frame girders oriented parallel to the second axis of rotation.
