ABSTRACT:
The invention discloses an Ultrafast Electro-Dynamic X, Y and Theta Positioning Stage. A positioning stage made according to this invention allows light payloads to be moved with extremely high linear and angular accelerations over finite distances and angles with a plane. An important feature of this invention is a momentum-cancelling design which allows reaction forces and torques on the fixed member to approach zero, thereby, allowing for a smooth and an ultrafast performance by the positioning stage.
