Improving the Performance of Piezoelectric Inertia Motors - Hunstig, Matthias; Hemsel, Tobias; Sextro, Walter (ACTUATOR 2010 Conference Proceedings, 2010)
A model based design approach for improved piezoelectric inertia motors is presented. Three velocityoptimized movement patterns for the driving body have been derived. The influence of the motor parameters and the process of designing an application specific motor with maximum velocity are shown. A simple dynamic model of the piezoelectric actuator is used to calculate the voltage signal for achieving the desired movement pattern. Observed distortions of the optimum pattern, their influence on the motion of the driven body and different methods to reduce them are discussed.
