The ABS positioning stage is a high precision, granite base, air bearing positioning stage for high end positioning applications. It is driven by an ironless core, non-cogging 3 phase brushless linear motor and guided by 5 flat magnetically preloaded air bearings floating on a granite base. The ironless core coil assembly is used as the drive mechanism for the AB stage because of its smooth, non-cogging operation. The lightweight of the coil and table assembly allows for high acceleration of light loads. The air bearings, which are used for supporting and guiding the payload, float on a cushion of air.

Motion Control -What To Consider When Specifying A Linear Slide

Motion Control – Tutorial

Considerations when specifying a linear slide for a new or existing application.

By Mike Quinn • LM76

When a design engineer has fully defined a linear-motion application’s requirements regarding travel length, speed, force, and accuracy as well as repeatability, the next question to answer is this:

Does an off-the-shelf linear slide (or a stock linear slide from a catalog) fully satisfy the application?

motion control - lm76

Off-the-shelf linear slides are advantageous for their quick delivery and lower cost than that of custom components. No wonder most linear-motion designs do in fact employ off-the-shelf linear slides from various component and system suppliers.

Motion Control Application – Open Screw Drive System Moves Heavy Sound Stage Sets Smoothly, Quickly, and Quietley!

Motion Control Application – High Speed Drive System

motion control - application


motion control - lm76E. Longmeadow, MA –Motion Control Application-

Problem: Move heavy sets on a sound stage smoothly, quickly, and most importantly quietly! Ball screws specified in the original design proved unacceptable due to the limited length of travel, screw deflection which resulted in a lack of smoothness, and high noise levels. A rack and pinion was also considered but the noise level was also too high and there was no room for a gearbox. Linear motors are quiet however the cost was prohibitive, and a belt system could not handle the heavy loads.

Solution: The new Streamliner Open Screw Drive System from Winner was selected by the production company to move the heavy sets on the sound stage.

Multi-Axis Motion for Lithography Masking

Challenge

A leading supplier of laser processing equipment to the semiconductor industry wanted a next generation masking system for extreme UV lithography. The customer approached Steinmeyer with a demanding set of requirements. The motion system needed flexibility to provide fine adjustment during processing and coarse movement into a service position outside the optical path. Travel of 160mm was required in the horizontal axis and 50mm in the vertical axis, with speeds up to 50mm/sec and repeatability of better than 2 microns. The mask also needed to tilt as much as 1.5 degrees around the optical axis. Finally, the dry nitrogen atmosphere and strict boundaries on contamination levels made the choice of materials and lubricants challenging.
