| Abstract: | A novel linear ultrasonic motor based on vibration with longitudinal and bending mode is presented in the paper.The motor is composed of a metal plate and 8 piezoelectric ceramic plates.There are four long holes in the metal plate,which is benefited to motor working in the resonant frequency.The electromechanical coupling of the stator of the motor is analyzed and the mathematical model of the motor is established.The ellipse motion of drive foot of the motor is gotten when the coupled vibrations with longitudinal and bending is excited.In the last, the feasibility of this linear ultrasonic motor are verified ecperimentally. |
