The SR1015B82 is a direct-drive (DD) servo actuator from Yokogawa’s DYNASERV series. This actuator integrates a high-torque, low-speed servo motor with a built-in high-resolution feedback system to achieve precise, backlash-free motion. It is designed for use in precision automation equipment, robotics, semiconductor handling systems, and other applications where accurate positioning and smooth rotation are essential. Its direct-drive design eliminates mechanical transmission components such as gears or belts, increasing accuracy, responsiveness, and reliability.
