The restriction on the use of lead in electronic components has prompted research into new piezoelectric materials in search of alternatives to traditional lead-based materials. Potassium sodium niobate (KNN) ceramics have emerged as a promising candidate to replace lead zirconate titanate (PZT), the most commonly used material in the manufacture of piezoelectric actuators, transducers, sensors and motors. In this work, a numerical model of a linear piezoelectric motor was developed using the finite element method to compare the performance of KNN and PZT ceramics. The frequencies and vibration modes that generate the largest deformations in each material were determined. The simulation results revealed that PZT ceramic exhibits 20 times greater deformation compared to KNN. This suggests that KNN ceramic requires hardening additives to optimize displacements in lead-free piezoelectric motors.
