The operating principle is based on coordinated motion of a number of highly preloaded linear and shear piezo elements acting on a runner and does not involve rotation\/linear conversion. The working principle is non-magnetic, vacuum &amp; clean room compatible.<\/p>\n<p><strong>Open &amp; Closed Loop Operation<br \/>\n<\/strong>N-216 comes in two versions for open- or closed-loop operation, as well as in two different load configurations. Closed-loop versions are equipped with a linear encoder for direct position measurement of the moving runner. The encoder features 5 nm resolution over the full travel range. In open-loop operation a positioning resolution to 30 picometers can be realized by use of the (high-dynamics) analog operation mode.<\/p>\n<div id=\"attachment_1120\" class=\"wp-caption alignright\" style=\"width: 350px\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-1120 \" title=\"N-216 NEXLINE\u00ae High-Load Actuator\" src=\"http:\/\/www.expo21xx.com\/news\/wp-content\/uploads\/nexline-e1334314673678-350x208.jpg\" alt=\"nanopositioning actuators\" width=\"350\" height=\"208\" \/><p class=\"wp-caption-text\">Photo by Physik Instrumente (PI) GmbH &amp; Co.KG<\/p><\/div>\n<p><strong>Extreme Reliability, Virtually Unlimited Lifetime<br \/>\n<\/strong>NEXLINE\u00ae drives have many high-end applications from ultra-precision manufacturing and semiconductor test equipment to astronomy and high energy physics applications. They excel when the requirements for high forces, precision, lifetime and stability are paramount. The extreme reliability makes them ideal for applications in difficult-to-access internals of instruments, where nanometer-realm adjustment and \/ or vibration cancellation are required. To promote long lifetime, the PiezoWalk\u00ae controller can reduce the operating voltage on all the piezo elements to zero at any position without affecting the full holding force (up to 800 N, 177 lbs).<\/p>\n<p><strong>PiezoWalk\u00ae Working Principle Allows Different Operation Modes<br \/>\n<\/strong>NEXLINE\u00ae drives overcome the limitations of conventional <a title=\"nanopositioning systems\" href=\"http:\/\/www.expo21xx.com\/motion21xx\/13788_st3_minimotor\/default.htm\" target=\"_blank\">nanopositioning systems<\/a> in their combination of long travel ranges and high resolution and stiffness. The piezo ceramic clamping and shear elements act directly on a moving runner coupled to the load. For maximum velocity, and long distance movements, the runner can be driven in full step mode. Extremely uniform motion and constant velocity is achieved with the nanostepping mode. In addition to combining long travel ranges with piezo-class precision, NEXLINE\u00ae PiezoWalk\u00ae drives also offer a high-dynamics analog operation mode (100&#8217;s of Hz) over smaller distances (to 6 \u00b5m)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>N-216 NEXLINE\u00ae high-load linear motors are ultra-precision nanopositioning actuators with travel ranges to 20 mm and push \/ pull forces to 600 N.<\/p>\n","protected":false},"author":3,"featured_media":1120,"comment_status":"closed","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"footnotes":""},"categories":[4],"tags":[98,58,56,99],"class_list":["post-1038","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-motion-control","tag-actuators","tag-drive-system","tag-metrology","tag-nanopositioning-systems"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v28.7 -
