<p style="text-align: center;"><img src="/ueditor/php/upload/image/20230209/1675929577924796.png" title="1675929577924796.png" alt="4.png"/></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">PI is introducing a new series of&nbsp;direct-drive, <a href="https://www.freerunbearing.com/products/Ball-Bearing/79.html" target="_blank"><strong>ball bearing</strong></a> rotary stages&nbsp;to supplement their A-62x series of air bearing spindles. The V-62x stage family is designed for 24/7 applications that require high precision motion with eccentricity and flatness deviations below 1 ?m and high stiffness. The new rotary stage family can be mounted and operated in any orientation, a critical feature for many industrial automation applications.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;"><br/></span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Designed for a New Level of Precision and Performance</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Based on&nbsp;PI’s&nbsp;extensive knowledge in the design and manufacture of ultra-high-precision rotary tables with air bearings, the new V-62x mechanical bearing rotary stages were designed to provide exceptional performance regarding travel accuracy, flatness, and wobble. The ultra-precise <a href="https://www.sunspeedbearing.com/products/Deep-Groove-Ball-Bearing/956.html" target="_blank"><strong>deep groove ball bearings</strong></a> are preloaded and lubricated prior to delivery, meaning they are maintenance-free for the whole lifetime of the rotation stage.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;"><br/></span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Direct-Drive Torque Motor - Friction and Maintenance Free</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Three-phase torque motors are at the heart of the direct-drive rotary stages, transmitting torque directly and friction-free to the motion platform. Advantages of a direct-drive design over a worm gear drive are higher velocity and acceleration, faster response, as well as the total lack of backlash and no friction in the drive train.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;"><br/></span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Choice of Encoders: Absolute and Incremental</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Absolute encoders supply explicit position information that enables the direct determination of each angular position – a great advantage over the traditional counting of increments. Therefore, position information is immediately available after power up without referencing, improving both efficiency and safety during operation.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;"><br/></span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Motion Controllers</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Single and multi-axis, ACS-based motion controllers and servo drives are available for single axis applications of the rotary stages or multi-axis, multi-degree-of-freedom sub-assemblies — also available from PI.</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;"><br/></span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Application Fields</span></p><p style="text-align: justify;"><span style="font-family: arial, helvetica, sans-serif; font-size: 14px;">Optics and Photonics, Sample Inspection, Metrology, Semiconductor Testing &amp; Inspection, Industrial Automation, Measuring Technology, Precision Micro-Assembly, Biotechnology.</span></p><p><br/></p>
