Abstract
This paper deals with the structure and theory of three beam Longitudinal Bend Tortional (LBT) stationary uItrasonic motor and reports the moving characteristic of LBT vibrator.We obtain various features of vibration frequency and model versus the motor size.The motor's characteristics were tested,and the driving electric circuit was made.This motor has some merits over single beam LBT motor,maybe promise well in application.
