Description

MMX-Z-25-Miniature Linear Stage Design Features

  • Unique motor design provides the compact linear actuator smoother motion with industry leading velocity stability

The brushless and ironless linear servo motor inside our miniature linear stage allows for high speeds with no maintenance, making it ideal for use in high throughput applications. Furthermore, it delivers cog free smooth motion coupled with an impressive 6 μm TIR accuracy and a 0.4 ± μm repeatability.

Counterbalance Capability

  • < 0.2 kg: Not Required
  •  0.2 kg – 1.5 kg: Magnetic Counterbalance
  • 1.5 kg – 4.5 kg: Pneumatic Counterbalance

 

  • Smallest package size using direct drive linear motor technology in a 1-inch travel positioner

Direct drive linear motor technology utilizes a direct power transfer mechanism and, in most cases, is a better alternative to a traditional mechanical transmission system, delivering valuable benefits to its users. These benefits include enhanced precision, reduced wear, faster response times, and quieter operation for seamless integration.

  • Lower cycle times with the most powerful servo motor design in a small form factor

MMX linear stages use high precision anti-creep crossed roller bearings for extremely smooth motion, high stiffness, and reliability in a low profile package. This allows for higher throughput without increasing the overall height.

  • Increased throughput with fast settling due to stiff cross roller bearings and a powerful motor

MMX cross roller bearings

  • Best-in-class accuracy from high-resolution encoder feedback and servo control

The miniature linear stage- MMX-Z-25 delivers 6 μm TIR accuracy. Additionally, it is equipped with an adjustable mount for externally adjustable limit sensors.

Options

  • 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)

Applications

For high throughput objective focusing applications, the MMX-Z-25 stages delivers excellent mechanical and servo stiffness to optimize motion for:

  • 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
