The new MMX™ high power motor has a higher force density to deliver 5 times the force of similar products from other companies. This miniature linear 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.

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


  • Motor options available: ironless direct drive servo motors
  • Feedback options available: linear encoder with analog or digital (1 or 0.1-micron resolution are standard, other resolutions available upon request)


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
