Abstract

The rotational characteristics of an ultrasonic motor using travelling wave are analyzed by employing a simple model for driving mechanism. A travelling wave is excited in the stator of annular shape by using a piezoelectric driver and the amplitude of the effective vibration in the circumferential direction is amplified by making a number of teeth on the stator's surface. The torque-revolution relation of the motor is calculated by assuming that the rotor is driven by the frictional force acting from the vibrating stator and that the contact force on each tooth varies in proportion to the contact time to the rotor surface due to the elliptical motion of the teeth. It is shown that the calculated results are in agreement with the experiment conducted on a model motor.
