A servo motor is a type of motor that provides precise control of angular position, velocity, and acceleration. It typically consists of a motor coupled to a sensor for position feedback. This allows the servo motor to adjust its position accurately based on the input signal it receives, making it ideal for applications requiring high precision, such as in robotics and automation. Servo motors are commonly used in various devices, including robotic arms, RC vehicles, and industrial machinery. They can be classified into different types, such as AC servo motors and DC servo motors, each suited for specific applications based on their performance characteristics.
