Elements of Modeling and Simulation for Piezoelectric Motors

Abstract:

In order to obtain a high rotational speed in comparison with the known embodiments, due to the increased amplitude of the contact point between the rotor and the active element, due to the possibility of adjusting the speed by changing the frequency of the two signals applied to the coupled discs, or due to the phase shift between the signals if the discs are supplied at the same frequency, it was achieved a stator by a non-removable coupling of two active elements. Modelling was performed in Comsol Multiphysics. In this respect we studied the variation of the strains and of the electrical potential, taking into account the changing of the parameters like the power voltage frequency, the power voltage amplitude, the distance between the support point and the edge of the discs system.
