Abstract :
A new concept of a two-coordinate ultrasonic linear motor, based on the superposition of longitudinal vibrations of rod-shaped rectangular resonators, is presented. The new motor is capable of bidimensional nanometric step displacements with travel range in the centimeter range. Controlled linear motion with steps of less than 10 nm is demonstrated. We compare the influence of the friction pair materials on motor output characteristics. CVD-diamond, alumina ceramics and case-hardened steel were used as friction pair materials. Wear and surface microtopography were measured by Atomic Force Microscopy (AFM). Strong ultrasound influence on wear and deformation of the friction pair materials was found
