Miniature Linear Motor Stages with Built-in Controllers - X-LDA-AE
Zaber's X-LDA-AE Series devices are motorized linear stages delivering high speed, precision, and reliability in a compact package.
A centrally mounted linear encoder results in up to 1 µm position accuracy and consistent movement steps down to 20 nm. X-LDA-AE devices feature non-cogging ironless linear motors, providing high speed and acceleration capabilities. Both the drive and encoder are non-contact, and have no moving cables, resulting in an extremely robust system.
• 200 nm repeatability; 1 µm accuracy; 20 nm minimum incremental move
• Direct position measurement from 1 nm resolution linear encoder
• Up to 0.8 m/s speed; up to 4 g acceleration
• 25 - 150 mm travel options

PI USA - Difference between Gantry & Split-Bridge
A traditional gantry system employs X-Y or X-Y-Z range of motion. Mounted on a base plate, usually granite, 2 parallel rails constitute the synchronized Y axis motion while the cross axis (bridge axis) provides the X motion. A vertical axis can be added on the bridge for the Z motion. A Split Bridge system can be less complex than a traditional gantry system because synchronization of the two parallel linear motors is not required. Both systems are used in industrial production, testing, and additive manufacturing.
