Dual-channel magnetic and optical incremental encoders (up to 4096 CPR) for precise position control in closed-loop servo systems.
Targeted drive solutions engineered for high reliability, low noise, and extreme environmental durability.
Proven micro-motion implementations designed to accelerate system development in South Korea.
Daejeon’s booming bio-health and surgical device cluster requires micro motors with ultra-low electrical noise, coreless smooth rotation without cogging torque, and autoclavable IP-rated seals for laparoscopy devices and automated syringe pumps.
Collaborating with regional aerospace labs, our precision micro hydraulic motors and planetary gear actuators undergo stringent thermal testing ($-40^\circ\text{C}$ to $+125^\circ\text{C}$) to guarantee zero-fail performance in drone gimbals and target tracking units.
As KAIST and local mechatronics hubs pioneer bipedal and quadrupeds, our high-power-density micro actuators deliver precise joint articulation with high overload protection and high torque-to-weight performance.
