- Extra-large, high-efficiency linear motor minimizes heat generation
- Ironless moving coil has no cogging for ultra smooth velocity control
- Ultra-quiet anti-creep crossed roller bearings assure ripple-free motion without cage migration
- High precision glass scale encoder provides accurate position feedback with 50 nm repeatability
- Sub-nm resolution with low interpolation error for outstanding speed stability and motion sensitivity
- No moving cables inside the stage, reduced particle generation and improved reliability
