Abstract :
A linear in form of a mechanical clutch system for the transmission of the force produced by a piezoelectric stack to a shaft is presented. Following an Inchworm motion principle, avoiding wear and giving an accurate positioning, this motor should generate high linear forces up to 1500 N on infinite strokes. The force and displacement values given by the FEM simulations of the piezoelectric stacks are in accordance with the mathematical model. The further development is the motor prototyping to confirm the simulation results.
