PI’s family of miniature micro and nanopositioning stages is expanding with the new RS-40 rotary stage and M-111 linear stages as engineers gave specific consideration to material selection, use of lubricants and coatings, and outbaking temperatures for high and ultra-high vacuum conditions. With 360-degree rotation range and 20-N load capacity, the RS-40 V7 stage boasts […]
Large variety of precise xyz axis stages now available
OES (Optimal Engineering Systems) has introduced a series of high precision, low cost XYZ positioning stages that can be easily integrated into new and existing applications. They are offered in 5 travel lengths for each axis, 50 mm (1.969 in.), 100 mm (3.937 in.), 150 mm (5.906 in.), 200 mm (7.874 in.), and 300 mm […]
New multi-axis stages: Driving dynamics in one plane for top performance
Having all of a stage’s driving dynamics in one plane can prevent problematic reaction torques on sensitive workpieces … and maximize machine performance for demanding motion applications. By Mathys te Wierik • Lead system engineer Jan Willem Ridderinkhof • Manager of R&D and engineering | PM B.V. High-end mechatronic motion solutions have proliferated as various […]
Hexapods precisely jostle cameras during image-stabilization testing
The six-axis parallel-kinematics systems known as hexapods excel in motion simulation and testing of mechanical and drive systems, multi-dimensional position sensors, and (the focus of this article) image-stabilization designs for cameras and video equipment. By Doris Knauer • Project Manager — Industrial Automation | Physik Instrumente (PI) Modern camera systems are capable of astounding feats, […]
What are planar motors and where are they used?
Linear motors are often described as rotary motors cut open and rolled out flat, so they produce motion in a straight line along one axis. Their construction is relatively simple, with a primary part (also referred to as a forcer) that contains windings, and a secondary part that contains magnets. The primary part is typically […]
Compact, open-aperture voice coil stages from Moticont
Moticont has debuted the HCDS-051-051 Series of eight linear open-aperture voice coil stages. These compact open-aperture stages have a small footprint of just 10.500 in. (266.7 mm) long x 4.000 in. (101.6 mm) wide x 3.755 in. (95.4 mm) high. Linear dc motor driven stages (also known as moving coil) are clean, quiet, and efficient, […]
New simulation software from PI aids hexapod selection
Powerful new simulation software from PI (Physik Instrumente) determines if a hexapod is suitable for a specific positioning task, in terms of workspace, load, center of mass, and operating orientation. The tool helps in making the correct choice for the application at hand. A hexapod, also known as a Stewart Platform, offers motion in 6 […]
Industry first: XY stage with 800 x 800 mm open center
Intellidrives now offers open-center XY stages with travel of 600 x 600 mm and open center dimensions of 800 x 800 mm. The demand for a high accuracy, robust, open-frame stages is met with Intellidrives dual-axis, large aperture stages, which address the unique needs of scanning microscopy, wafer and printed circuit board inspection, automated assembly, […]
Dual-axis pitch and roll stages precisely measure curvature and angles
The precise measurements of angles and the curvature of objects are easily determined using two new Pitch and Roll stages from OES (Optimal Engineering Systems, Inc.) The PR100-45-01 is driven by stepper motors and the PR100-45-02 is driven by brushless servo motors with quadrature incremental optical encoders. The pitch axis (lower stage) is a high-precision […]
XY2Z-theta motion system improves wafer inspection for the semiconductor industry
For more than fifty years, the Dutch linear-motion company PM has developed and produced precision linear and rotating bearings and slides. It focuses on applications requiring smoothness and stiffness from their linear bearings … and continues to expand its standard range of linear components. But customization is becoming the norm — and now, catalog products […]
