Ultrasonic linear motor

Precision miniature ultrasonic linear motor consisting of a plate-shaped Ultrasonic oscillator with two flat, parallel rectangular Major surfaces, with two end faces, two side faces, one with at least a guide rail in coincidence located ends and consisting of two movable Friktionsteilen Element, a friction effect with the board about the side surfaces respond to each of the friction parts, characterized in that the side surfaces of the Oscillator plate as faces accomplished are and are so inclined to the longitudinal plane of symmetry under the same angle, the line of intersection of the surfaces the side surfaces the longitudinal plane of symmetry parallel to the major surfaces of the plate are disposed, wherein the friction parts of the movable Element with each other via a compression spring are connected and the forces occurring in the Friction parts of the movable element to the respective side surfaces of the Press the panel and the movable member to the guide rail, wherein the relationship these forces by the inclination angle of the side surfaces to the longitudinal symmetry plane of the plate is determined.
