Description
The DDM includes embedded direct drive, three phase ironless linear motors, stiff anti-creep crossed roller linear guideways, and optical linear encoders for accurate and repeatable servo position feedback. This stage is designed to provide imaging throughput of up to 30 images per second with outstanding stability during image capture. Dover also offers fully integrated servo motion controllers to support manual operation or fully automated control for production or diagnostic laboratory environments.
Design Features
- Backlash free direct drive motor
