Abstract :
A linear piezoelectric step motor (LPS) driver using a current source inverter is proposed in this study. The mechanism of operation of an LPS motor is first described. Then, a single-phase equivalent model of the LPS motor is introduced. A detailed theory of the driving circuit design using current source inverter for the LPS motor is explained. At the end the simulation and experimental results are presented and compared.
