DGSMARTWIN KYAC2000 and KYAC4000 Series: Precision-Matching Full-Scenario Vertical Motion Requirements with Differentiated Coreless Architectures


In the field of industrial precision transmission, DGSMARTWIN’s KYAC2000 and KYAC4000 series coreless linear motors form a differentiated product matrix through their coreless technology core and modular design. Tailored for miniaturized integration scenarios and medium-to-large power demand scenarios respectively, they deliver precise and efficient solutions for vertical axis transmission needs across different levels of industrial automation.


As two products belonging to the coreless linear motor family, the KYAC2000 and KYAC4000 series share core technical advantages, precisely meeting the stringent requirements of vertical axis transmission:First, leveraging coreless technology, they fundamentally eliminate cogging effects, achieving smooth dynamic profile motion with low thrust ripple and ensuring the smoothness and stability of vertical movement. Second, they feature both compact volume and zero vertical magnetic attraction, which not only significantly reduce equipment installation space but also effectively address the industry pain points of vertical axis brake design burdens and load disturbances. Third, they adopt a unified modular ordering rule design, allowing flexible combination of movers and stators. This supports engineers in precise model selection based on actual working conditions, greatly enhancing the flexibility and efficiency of equipment integration.

KYAC2000 Series: A Benchmark for Miniaturization and Lightweight Design, Adapting to Precision Scenarios in Micro-Spaces


Available in two stator lengths (A1: 120mm, A2: 180mm) with a magnetic pitch of 30mm and a mass of only 5kg per meter, the series offers a range of mover lengths from model 2001 (66mm) to 2004 (246mm). It comes with an LA05 cable option (0.5-meter cable output), making it ideal for space-constrained scenarios such as precision instruments and micro-automation equipment. As a benchmark for miniaturization and lightweight design, it is the perfect choice for small-scale vertical axis transmission.

KYAC4000 Series: A Core for Medium-to-Large Power, Supporting High-Demand Transmission Scenarios


With two stator lengths (A1: 156mm, A2: 312mm), a magnetic pitch of 39mm, and a stator mass of 26.3kg/m for both A1 and A2 specifications, the series covers medium-to-large mover models including 4002 (163mm), 4003 (241mm), 4004 (319mm), and 4005 (397mm). It is equipped with an L05 cable option (0.5-meter cable output). Capable of providing greater thrust and longer stroke support, the series precisely meets the needs of medium-to-large vertical axis transmission scenarios with higher requirements for thrust and stroke, such as semiconductor manufacturing, high-end machine tools, and high-end pick-and-place machines, ensuring motion smoothness under high dynamic response.

The choice between the KYAC2000 and KYAC4000 series is a precise engineering decision based on load mass, motion stroke, installation space, and dynamic performance requirements. For ultra-precision micro-operation scenarios that pursue extreme space savings, drive extremely light loads such as optical lenses and micro-probes, and typically involve strokes within 100mm, the KYAC2000 series is the ultimate choice for achieving equipment miniaturization and high precision, thanks to its minimal installation footprint and thrust adapted to micro-loads. For medium-sized precision equipment that needs to drive loads from hundreds of grams to several kilograms, with strokes ranging from 200mm to 400mm and requiring high dynamic response and smoothness (such as high-end pick-and-place machine heads and vertical axes of precision measurement probes), the large-thrust and long-stroke modules of the KYAC4000 series are perfectly suited.


Through the parallel deployment of the KYAC2000 and KYAC4000 series, DGSMARTWIN not only demonstrates its profound accumulation in coreless direct drive technology but also builds the capability to provide precision motion solutions with "full-scale coverage and full-scenario adaptability". This empowers China's high-end equipment to achieve ultimate performance breakthroughs in both micro and macro vertical transmission scenarios.
