Made for motion control applications such as scanning, lens grinding, and laser and mirror polishing, these stages have up to 50.8 mm (2 inches) of travel, with no force or velocity ripple. They have higher performance and greater stability than belt or lead screw mechanical drive systems, with an encoder resolution as low as 0.0001 mm (0.1 micron), acceleration up to 98 m/sec squared (10g's), and no moving cables. The voice coil stages range from 0-222N (0-50 lb) of continuous force and 667N (150 lb) of peak force. They need a linear servo amplifier available as a complete motion control system from H2W. Options include cross roller bearings, force transducer feedback, custom mountings, and complete custom designs. H2W Technologieshttp://rbi.ims.ca/4928-635
