Abstract
The development of a linear transducer type piezoelectric motor is shown. This design utilizes the Inchworm principle and features a cylindrical device operating inside a metal tube. The motor is capable of developing high translational forces with macro and micro positioning capabilities. It consists of two cylindrical clamping elements separated by a central driver element which are physically connected but capable of independent operation through three multi-layer actuator stacks connected to a three channel controller. Inchworm type movement is possible through sequential activation of the three elements which allows linear motion along the tube.
