Abstract
A high resolution actuator is provided which can be used in extreme environments, e.g., at extremely low temperatures. The actuator uses electromagnetic forces to actuate levers which then cause rotation of a lead screw. The actuator uses very small gaps in the magnetic circuit to achieve a high force with a small input power.
