Technical Information<\/strong><\/span><\/p>\n

Mechanism of Stage<\/p>\n

\u201cCoarse movement feeding in millimeter \u201d and \u201cfine movement feeding in nanometer\u201d are possible.
\nAchieve long travel distance and high resolution concurrently.<\/p>\n

\"\"<\/p>\n

Principles of movement<\/span>
\n<\/strong><\/span><\/p>\n

Rough motion and fine motion operation principle<\/p>\n

\"\"<\/p>\n

(1) The piezo-electric element is slowly elongated and the trolley table advances.
\n(2) The piezo-electric element is abruptly shrunk and the friction part slides to move.
\nRepeat (1) and (2) above for rough motion in mm
\n(3) DC voltage is applied to the piezo-electric element for high precision positioning to the target position.
\nEven after stopping, linear scale signals are fed back to maintain the position control.<\/p>\n","protected":false},"excerpt":{"rendered":"Appearance Products Name Maker \u00a0 Ultrasonic Motor Stage A high precision stage that can control positioning wi …","protected":false},"author":5,"featured_media":1461,"parent":0,"menu_order":0,"comment_status":"closed","ping_status":"closed","template":"page-onecolumn.php","meta":[],"acf":[],"aioseo_notices":[],"_links":{"self":[{"href":"https:\/\/www.jpu.or.jp\/eng\/wp-json\/wp\/v2\/pages\/5776"}],"collection":[{"href":"https:\/\/www.jpu.or.jp\/eng\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.jpu.or.jp\/eng\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.jpu.or.jp\/eng\/wp-json\/wp\/v2\/users\/5"}],"replies":[{"embeddable":true,"href":"https:\/\/www.jpu.or.jp\/eng\/wp-json\/wp\/v2\/comments?post=5776"}],"version-history":[{"count":11,"href":"https:\/\/www.jpu.or.jp\/eng\/wp-json\/wp\/v2\/pages\/5776\/revisions"}],"predecessor-version":[{"id":7795,"href":"https:\/\/www.jpu.or.jp\/eng\/wp-json\/wp\/v2\/pages\/5776\/revisions\/7795"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.jpu.or.jp\/eng\/wp-json\/wp\/v2\/media\/1461"}],"wp:attachment":[{"href":"https:\/\/www.jpu.or.jp\/eng\/wp-json\/wp\/v2\/media?parent=5776"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
