Yokogawa Electric Corporation SR1015B85 DC Servo Actuator

The Yokogawa SR1015B85 DC Servo Actuator is a direct-drive, outer-rotor servo system (DYNASERV) that eliminates mechanical transmission components, delivering zero backlash and improved positioning accuracy for high-speed, high-torque motion control. It operates on 200–230 VAC (50/60 Hz) and is typically paired with a compatible Yokogawa servo amplifier for closed-loop control with encoder feedback. With a direct-drive configuration—no gears or belts—the actuator provides streamlined maintenance and exceptionally smooth, responsive rotation. The integrated actuator design is intended for machine installation in industrial automation, where precise rotational motion is required, and it supports high torque at high speeds while preserving repeatable positioning. Common applications include semiconductor manufacturing equipment, robotics, indexing tables, inspection equipment, and automated assembly systems, enabling rapid indexing, precise alignment, and reliable performance in demanding environments.
