Linear shaft motor stage offers nanoprecision

Nippon Pulse America recently introduced an ultra high-precision, compact single-axis stage that integrates a slide guide, encoder and linear shaft motor. The SCR100 stage is said to offer a wide range of advantages for ultra high-performance and accuracy applications, according to Nippon.

The SCR100 high-precision, cross-roller linear stage from Nippon.

The motor, a coreless direct-drive linear motor, allows for more resolution, speed and continuous force than standard stepper motors and piezo servomotors, Nippon reported.

With its moving magnet design, which locates all cables and connectors in the stationary base, the SCR100 stage eliminates motion errors due to cable forces. Together with the precision ground cross roller way, the SCR100 is capable of supporting higher torque levels due to offset loads with travels from 50mm to 300mm.

Plus, the built-in, non-contact optical linear encoder is available with resolutions from 1µm to 10nm with digital output. The sub-micron resolution results in a high-accuracy stage, which is laser-tested for optimum performance.

The stage is suitable for markets such as metrology, spectroscopy, digital pathology, microscopy, disk drive, semiconductor fabrication, biomedical, pharmaceutical, life sciences, cell imaging, particle analysis, stent fabrication, national laboratories, photonics and telecommunications, aerospace and defense, and genomics.
