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

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":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
