A Rotary Actuator is a device that converts energy into rotational motion. It is commonly used in various applications, such as robotics, automation, and industrial machinery. These actuators can be powered by different sources, including electric motors, hydraulic systems, or pneumatic systems, allowing for precise control of movement. Rotary actuators are essential components in systems that require the rotation of parts, such as valves, gears, and robotic arms. They can provide high torque and speed, making them suitable for tasks that demand quick and efficient operation. Their versatility makes them valuable in fields like manufacturing and aerospace.
