Abstract

In an ultrasonic motor consisting of a stator made of an elastic material and having one or more ultrasonic oscillators for exciting travelling waves and of a rotor, stator and rotor each being in contact with one another in a surface region under pressure, provision is made that, to drive the rotor with different transmission ratios, progressive waves of different vibration types are excited in the stator surface. <IMAGE>
