【Abstract】 A kind of mode conversion ultrasonic motor is studied and made. The formula of the force and the response of the fiexcural vibration to the transient fricational force is given,and the relation among the fabricational angle, the driving force of the motor and the phase difference is discussed. The rotatory speed is measured. The results show many merits of the motor, such as simple construction, low speed, etc.更多还原
