| Abstract: | The ultrasonic motor is a sort of new type of micromotor, whose rotatingforce is yielded by piezoelectric vibration. It's operating principle is quitedifferent from the traditional motors. The construction of a travelling wavetype ring ultrasonic motor is introduced in this paper,and the operating prin-ciple is also analysed in the following. The design thought of its frequency-modulated control power source is proposed to meet the special operatingmanner of this motor. |
