【VINKO NEWS】New Direct-Drive Nanometer Positioning Platform Launched: Yinguang Delivers a Domestic Ultra-precision Motion SolutionMotion Solutions

[VINKO, 27 Oct 2026] VINKO launches the NS Nano-positioning Direct-Drive Ultra-precision Stage.As automation equipment demands ever-higher intelligence, ultra-precision motion platforms are facing upgraded requirements for positioning accuracy, in-position stability and dynamic performance in high-end fields including silicon photonics coupling, semiconductor inspection, ultrafast laser machining and super-resolution microscopy. Featuring a proprietary technical architecture, the nano-positioning direct-drive stage serves as a core motion component for high-end precision manufacturing.

What is a nano-positioning ultra-precision stage?

The nano-positioning direct-drive ultra-precision stage is a high-end motion unit built around direct-drive linear motors and high-resolution grating full-closed-loop feedback. Eliminating intermediate transmission elements such as ball screws and belts, it delivers zero backlash and ultra-smooth motion. It achieves nanometer positioning and low-jitter in-position stability over travel ranges from tens to hundreds of millimeters, supporting one-step workflow combining large-range coarse positioning and nanoscale fine alignment. Configurable for multi-axis assemblies and capable of long-duration continuous operation, the product is widely deployed for silicon photonics coupling, semiconductor inspection, ultrafast laser machining and optical precision alignment. It delivers high-performance motion support for the localization of high-end precision equipment.

✨ Core Product Highlights

Ironless Linear Motor Architecture

· Zero cogging force for ultra-smooth low-speed motion and minimal velocity ripple.

· No magnetic attraction between mover and magnet track; stable guide preload for extended service life.

· Lightweight mover with low inertia for superior acceleration performance: fast response, short settling time and high mechanical bandwidth.

Nanometer-class Encoder

· Equipped with high-precision linear nano-encoders featuring SINCOS interpolation sampling, delivering positioning and repeatability accuracy at the ±0.1 μm level.

High-precision Anti-creep Crossed Roller Guideways

· High-grade crossed roller guides provide superior straightness and smooth travel within a compact footprint, combining high precision with low friction.

· Anti-creep design ensures uniform wear and lubrication under high-cycle, short-travel motion, extending service life.

Diverse Assembly Configurations

· Supports common single-axis, 2-axis and 3-axis layouts to accommodate varied application scenarios.

· Combined integral and modular construction enables fast, accurate custom solutions.

Moving Magnet Design

· Moving magnet configuration features a lightweight, low-inertia mover for outstanding dynamic performance.

· Heat is isolated from the moving assembly to minimize thermal disturbance.

· Cables remain stationary without travelling with the mover, reducing cable-induced perturbation and fatigue wear.

Matching Motion Control Solution

· Custom drive and motion control packages are available. Paired with high-precision low-voltage servo drives, the system enables refined control for superior accuracy and responsiveness in ultra-precision applications.
