Dover Ultra Compact, Linear Motor Stages
Double the accuracy, not the cost
The Mini-MAG (MMG) line of positioning stages blends the ultimate in performance, reliability, and value, delivering nearly twice the accuracy at virtually the same cost as standard-grade options. Short lead times can speed up your time to market or give you greater machine uptime. The MMG will help you build a better machine—faster.
See How it WorksFeatures & Benefits
- Discover the smallest package size using direct drive linear motor technology in 1” travel positioner
- Attain lower cycle times with most powerful servo motor design in small form factor
- Increase throughput with fast settling thanks to stiff cross roller bearings
- Achieve stable scan motion through Dover precision design
- Customizable and stackable design ensures fit within unique applications
- Get best-in-class accuracy from high resolution encoder feedback and servo control
