摘要

In the present work a travelling wave ultrasonic motor (TWUSM) is proposed. It is composed of an annular shaped stator and of two cone-shaped rotors that are pressed in contact to the borders of the inner surface of the stator. A rotating travelling wave has been generated in stator by using as vibration generators two Bolted Langevin Transducers (BLT) oppurtunely shifted in space and in time. The vi-brational behaviour of the stator as well as the travelling wave generation have been simulated with a finite element method (FEM) software. A prototype of the motor has been manufactured and experimentally characterized. It exibits a static torque of about 0.8 N·m and a maximum angular speed of about 300 rpm. Possible variations of the present design aimed to increase output torque or minimize encumbrance are described and discussed.
