The Yokogawa SD1050A02-2SN is a direct-drive (DD) servo actuator from Yokogawa's DYNASERV series, designed for high-precision motion control applications. This actuator integrates a high-torque, low-speed servo motor with a built-in high-resolution feedback system, eliminating the need for mechanical transmission components such as gears or belts. This design results in backlash-free motion, high accuracy, and excellent dynamic response. It is suitable for use in robotics, semiconductor equipment, precision automation systems, and other applications requiring precise positioning and smooth rotation.
