A servo is a closed-loop system used to precisely control the position, velocity, or torque in an electromechanical application.
In manufacturing, servos are commonly used to achieve high precision in automation systems, typically enabling accurate positional control of machine elements. They consist of a motor coupled with a sensor for position feedback and a control system that compares the desired target position to the actual position and adjusts accordingly. This ensures precise movements, which are crucial in applications like CNC machining or robotic arms.
A FANUC servo motor is used in CNC machining to achieve precise cutting movements with a repeatability of ±0.01 mm (±0.00039 in).
Commonly used in CNC machines where high precision is required for metal cutting processes.
In the ABB IRB 6700 robot, servos provide joint movement with a positional accuracy of 0.05 mm (0.00197 in), allowing for precise assembly tasks.
Used in automotive manufacturing for tasks such as welding and component assembly.
