Actuating Mechanism and Design of a Double Driving Feet Linear Ultrasonic Motor Using Longitudinal Vibration Transducer

摘要：

　　A double driving feet linear ultrasonic motor using longitudinal vibration transducer is proposed in this paper.The stator of proposed motor contains a horizontal transducer and two vertical transducers.The horizontal transducer includes two exponential shape horns located at the leading ends,and each vertical transducer contains one exponential shape horn.The horns intersected at the tip ends where located the driving feet.The horizontal and vertical vibrations of driving feet are generated by the longitudinal vibrations of horizontal and vertical transducers,respectively.Longitudinal vibrations are superimposed in the stator and generated elliptical motions at the driving feet.The two vibration modals of stator are gained with FEM,and the resonant frequencies of two vibration modals are degenerated by adjusting the structural parameters.Transient analysis of piezoelectric coupling states the good and strong elliptical motions of driving feet,and verifies the theoretical feasibility of proposed motor.
