VCDS-051-051-01-26 Voice Coil Linear Stage
Range of Motion: 0.75 in (19.1 mm) | Continuous Force: 6.3 lb (28.0 N) | Resolution: 26 micron

Product Overview

The VCDS-051-051-01-26 is a direct-drive voice coil linear stage designed for fast, precise, and repeatable positioning. It combines a non-commutated voice coil actuator, linear ball bearing guidance, quadrature optical encoder feedback, and a built-in home switch in a compact guided-stage assembly.

Performance and Construction

The stage provides a 0.75 in (19.1 mm) range of motion, 6.3 lb (28.0 N) continuous force, 19.9 lb (88.6 N) intermittent force at a 10% duty cycle, and 26 micron positioning resolution. The direct-drive architecture eliminates lead screws, belts, gears, and other transmission components, providing zero mechanical backlash, no cogging, rapid acceleration and deceleration, quiet operation, and long service life. Key electrical and mechanical values include a force constant of 1.8 lb/A (8.0 N/A), moving mass of 25.9 oz (735 g), total stage mass of 7.7 oz (3.5 g), and continuous power rating of 33 W. The motor electrical characteristics include 2.7 Ohm coil resistance and 1.2 mH at 1000 Hz coil inductance.

Applications

Optical and Laser Systems: Beam steering, focusing, scanning, mirror positioning, laser processing, and optical alignment.
Medical and Laboratory Equipment: Diagnostic instruments, sample handling, testing, imaging, and automated laboratory systems.
Industrial Automation and Metrology: Inspection, precision assembly, dispensing, sorting, packaging, measurement, vibration control, and research instrumentation.

Mechanical Integration and Closed-Loop Control

The payload can be attached directly to the guided moving table, eliminating transmission backlash and supporting high dynamic response. For closed-loop position or velocity control, use a compatible servo controller and current amplifier selected for the required force, speed, duty cycle, payload, and motion profile. Final positioning accuracy depends on the encoder, mechanical mounting, load, structural stiffness, controller, and servo tuning. Cable is not included; optional CBL-01 and CBL-04 cables are available.
