Tighter integration and programming take positioning stages into 21st century
Few motion technologies show more recent innovation than positioning stages. Their hardware and software are increasingly custom to fit specific output requirements, thanks in large part to tighter integration and advanced programming. No wonder that today’s positioning stages can make moves with incredible accuracy; synchronize complicated axis commands; and optimize travel from coarse and fine […]
Piezoelectric Positioners offer Precise Control in Nanopositioning Applications
By Stefan Vorndran and Scott Jordan, PI, Physik Instrumente L.P. Ever-increasing requirements for more precise motion control has forced manufacturers of piezoelectric positioners to find ways to overcome their limitations, such as travel range and linearity, while preserving the unmatched speed, reliability and resolution capabilities of piezoelectric devices. Precision motion control in general, and nanopositioning […]
What are Positioning Stages and Tables? Technical Summary
Updated May 2015. || Positioning stages and tables are used in motion control systems to hold down a work piece or position it for some operation. Stages or tables, whether linear or rotary, are most often complete motion sub-systems. That is, they are motion systems themselves comprised of components such as linear motion elements, motors […]
