Direct Drive Stages
Outstanding performance:
- Up to 1000 mm travel, 1500 mm/s speed, and 20 kg load
- Down to 80 nm repeatability, 1 µm accuracy, and 8 nm minimum incremental move
- 100% maintenance free direct drive motors and optical encoders
A linear motor stage, also known as a direct drive linear stage, offers a leap in performance over conventional screw-driven stages. Linear motors are suitable for demanding applications where speed, accuracy, and reliability are critical.
Zaber’s linear motor stage products combine this high performance with the flexible Zaber eco-system, lowering the barrier for nanometer-level motion control. Benefits include:
