Paper Abstract

Based on previous investigations an ultrasonic traveling wave motor for a linear motion is developed. The stator consists of straight and curved beams. In order to match the impedance of the piezoceramic elements the straight beams are notched. The notches have to be designed carefully to get two orthogonal bending modes with equal eigenfrequencies. A prototype stator was manufactured. The experimental results are encouraging.
