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 […]
New SIL 3 Safety Encoders from HEIDENHAIN
Safety-related position encoders have been available from HEIDENHAIN for several years. However, those encoders have been rated to SIL 2, PL d, Category 3. While this meets the requirements of most applications, sometimes there is a need for SIL 3, PL e, Category 4-rated equipment. These applications involve high risks for the operator, such as […]
James Fisher Nuclear Selects Moog Motion Control System
Moog Industrial Group has supplied a motion control system and engineering services to James Fisher Nuclear Ltd (JFN) for the ModuMan 100 Manipulator Arm which will be used for nuclear decommissioning. A manipulator is used to grasp and move materials without direct human contact. Typically a manipulator is an arm-like device with a number of […]
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 […]
