Chapter 3 Overview
3.1. Introduction
The PD1D(/M) stage features two piezo inertia motors that use friction and inertia to translate the platform in discrete
cycles. Each cycle consists of a relatively slow piezo expansion step accompanied by a rapid piezo contraction
step. During the expansion step, the moving platform moves in the same direction with the piezo element due to
friction, while the rapid piezo contraction causes the moving platform to slip and remain immobile due to inertia.
Continuous motion is achieved through repetition (“continuous stepping”) of this cycle and reverse travel is achieved
by performing the cycle in reverse.
The PD1D(/M) stage is a monolithic stage and provides two axes of 20 mm travel with open-loop operation and
better perpendicularity than two combined, discrete stages. When driven by the KIM101 or KIM001 Inertial Piezo
Controller, each axis of the PD1D(/M) stage offers continuous long term stepping as well as periodic position and
hold modes with 3 N clamping/holding force. The stage can achieve a typical step size of 1 µm using different rise
and fall voltage rates that depend on the load.
