Request InfoPI (Physik Instrumente) LP, Motion Control, Air Bearings, Piezo MechanicsAUBURN, Mass., June 5, 2017 — The N-331 OEM walking motor drive from Physik Instrumente LP has its configuration rooted in existing patented piezo actuator technology and a patented piezo stepping motion principle design. Unlike traditional electromagnetic motors, piezo motors do not create magnetic fields, nor are they influenced by magnetic or electric fields – characteristics that are advantageous in applications from e-beam lithography to MRI technology. When large optics, detectors or camera setups in industrial applications need to be positioned with nanometer precision, it can be beneficial to cut the...See full productRelated content from Photonics MediaPRODUCTSPhotonics Spectra October 2023 IssueCustom Air Bearing Motion SystemsCustom air bearing motion systems from Physik Instrumente LP are designed to enhance performance in various industrial applications such as photonics, medical design, aerospace, and semiconductors....Photonics.com 7/19/2022Stepper Motor Linear SlidesL-836 Stepper Motor Linear Slides from Physik Instrumente LP are motorized linear translation stages designed for multiaxis stacking with an optional linear encoder and a compact folded drive train....Photonics.com 8/18/2023Linear Servo ActuatorThe GVCM-095-064-01 Linear Servo Actuator from Moticont is a compact solution that merges high-precision with high-force capabilities.
