Founded in 1988, Samhyun makes motion control components, specifically 3-in-1 smart actuators and smart power units that integrate motor, controller and reducer from the design stage.
According to company materials, it developed Korea's first DCT motor and the world's first CVVD actuator, plus SBW, disconnect motors and MR dampers, winning Hyundai Motor, Kia and Hanwha Group as customers.
The revenue mix is still heavily tilted toward automotive electronic components; Samsung Securities said in a November 2025 report that about 85% of sales are auto parts, with motors and valves for internal-combustion engines and transmissions supplied to Hyundai Motor and Kia through Hyundai Transys.
The same report noted defense had risen to 13% of sales on a nine-month 2025 basis from 11% in 2024. In defense, the company supplies drive modules shifting from hydraulic to electric, including electric stabilizers, electric powertrains and radar drive units.
The third pillar is robotics, centered on AXLON, the humanoid joint actuator brand unveiled in July 2026, comprising 12 models: ten I-series rotary joint units, one QDD-type O-series and one linear L-series.
Production sits on smart-factory lines in Changwon, and the company told Electronic Times in July 2026 that automation exceeds 90% on auto part lines and reaches up to 95% in actuator processes.
On competition, Robotis is cited as the leader in robot actuators while SPG was reported to be preparing mass production around September 2026, and low-cost Chinese suppliers are another variable.
In short, the company is shifting its center of gravity from autos toward defense and robotics, and the cost of that shift is showing up directly in the income statement.
