Abstract
A simple mechanical model of a mode conversion ultrasonic motor is suggested. It is revealed that the vibrational motion of the beam´s tip is transformed into a unidirectional rotation of a rotor, owing to the dependence of the magnitude of the frictional force on the direction of slip. The model developed enables one to investigate the behavior of the motor in transient, periodic and steady-state modes of operation and to study the influence of the motor´s parameters on the maximum torque, velocity of revolution, efficiency etc.<>
