To meet the need of advanced manufacturing technology, a piezoelectric actuator with high resolution was developed in this work. The principle of exciting the driving tip to vibrate elliptically was analyzed in detail. A prototype was fabricated to validate the analysis. Testing results shows that this prototype can obtain a speed of 16.6mm/sec in the sinuous exciting voltage signal with peak to peak...
To meet the need of improving requirements for compact actuators in precision driving, a novel linear ultrasonic motor was proposed in this paper. The principle of this motor was introduced. With the help of commercial finite element analysis software ANSYS, finite element model of the stator of the ultrasonic motor was built and mode analysis was conduct to obtain an optimum design. A prototype was...
