A servo motor is a type of motor that provides precise control of angular position, speed, and acceleration. Unlike regular motors, which simply spin continuously, servo motors can move to a specific angle and hold that position. This makes them ideal for applications like robotics, where accurate movement is crucial. Servo motors typically consist of a motor, a feedback device, and a controller. The feedback device, often a potentiometer, helps the system know the motor's current position. This closed-loop system allows for smooth and accurate movements, making servo motors essential in various fields, including automated machinery and RC vehicles.
