HCDS-051-051-019-01-26 Hollow Core Linear Voice Coil Stage
Range of Motion: 0.70” (17.8 mm) | Continuous Force: 5.2 lb (23.1 N) | Aperture: 19.1 mm

Product Overview

The HCDS-051-051-019-01-26 is a direct-drive hollow core linear voice coil stage designed for fast, precise, backlash-free motion. Its central aperture allows optical beams, illumination, wiring, tubing, or other components to pass through the moving stage, making it suitable for compact optical, medical, industrial, metrology, and research systems.

Performance and Construction

The stage provides a 0.70” (17.8 mm) range of motion, 5.2 lb (23.1 N) continuous force, 16.4 lbs (72.9 N) intermittent force at a 10% duty cycle and a 19.1 mm clear aperture. The direct-drive design 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 Features

• Direct-drive linear motion with zero mechanical backlash
• Hollow-core stage architecture for through-aperture applications
• Precision guidance using a linear ball bearing
• Quadrature optical encoder feedback with 25.4 micron resolution
• Built-in home switch for repeatable initialization
• Black-anodized stage construction
• Pre-drilled mounting features for straightforward system integration
• Optional return-spring configuration where specified

Applications

Optical and Laser Systems: Beam steering, optical focusing, mirror positioning, scanning, switching, laser drilling, and laser machining.
Medical and Laboratory Equipment: Diagnostic instruments, sample handling, testing, imaging, and precision positioning.
Industrial Automation and Metrology: Inspection, alignment, oscillation, vibration control, precision assembly, measurement, and research instrumentation.

Mechanical Integration and Closed-Loop Control

The load can be attached directly to the guided moving table, eliminating transmission backlash and supporting high dynamic response. The stage includes pre-drilled and counterbored mounting holes for integration into new or existing equipment. 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.
