Abstract
The invention relates to an ultrasonic linear motor () comprising a plate-type ultrasonic oscillator () with two planar parallel main faces, two end faces and two lateral faces and a displaceable element () that engages with at least one guide rail () and has two friction parts, said element interacting with the ultrasonic oscillator to cause friction via the lateral faces of the friction parts. The lateral faces of the ultrasonic oscillator are planar and are inclined at the same angle in relation to a longitudinal plane of symmetry, in such a way that the intersection lines between the planes of the lateral faces and the longitudinal plane of symmetry run parallel to the main faces of the ultrasonic oscillator. The friction parts of the displaceable element are interconnected by springs.
