What is servo controls?

Servo controls utilize servomotors, which are rotary actuators or linear actuators that allow for precise control of angular or linear position, velocity, and acceleration. They typically consist of a motor coupled to a sensor for position feedback (e.g., a potentiometer or encoder) and a control circuit. Servos are commonly used in robotics, CNC machinery, radio-controlled vehicles, and other applications where precise and repeatable motion is required. They operate using a closed-loop feedback system, where the control circuit constantly monitors the actual position and adjusts the motor to match the desired position, minimizing errors.
