MINIATURE LINEAR STAGE – MMG

Description

The new MMX™ high power motor has a higher force density to deliver 5 times the force of similar products from other companies. This stage is also available with 3 phase servo motors in travels from 25 to 150 millimeters. Our miniature linear stage delivers nearly twice the accuracy at virtually the same cost as competitive standard-grade options. The MMX™ provides short lead times, reducing time to market for equipment manufactures and providing greater machine uptime for end users.

Applications for the compact linear actuator

For high throughput imaging applications, the MMX™ miniature linear stages deliver excellent mechanical and servo stiffness to optimize motion for:

  • Sample/part positioning: sustained throughput of up to 2000 moves per minute are possible
  • Focal plane definition: Z objective positioning moves (less than 5 microns) are often accomplished in less than 20 milliseconds, in parallel with XY stepping
  • Frame capture: in-position stability is key to producing quality images; position stability/jitter is typically less than 100 nanometers
  • Space savings: compact linear actuator designed to fit inside benchtop instruments

Design Features

  • Unique motor design provides the compact linear actuator smoother motion with industry leading velocity stability
  • Smallest package size using direct drive linear motor technology in a 1-inch travel positioner
  • Lower cycle times with the most powerful servo motor design in a small form factor
  • Increased throughput with fast settling due to stiff cross roller bearings and a powerful motor
  • Customizable and stackable design ensures fit within unique applications
  • Best-in-class accuracy from high-resolution encoder feedback and servo control
  • Highest load capacity of 500 grams without a counterbalance
