Modeling and simulation of a linear piezoelectric stepper motor in maplesim

Devices based on piezoelectric materials have traditionally been modeled in PDE simulation software. These simulations are expensive to create and run. In this paper it is shown that lumped-parameter models of such devices can provide good fidelity with low computational cost. Modelica models of supporting components, along with a system-level model of a linear piezoelectric stepper motor are presented. The simulation results show good agreement with published experimental results. Future research is proposed based on the components and model.
