AC Servo Motor is a type of rotary actuator or motor that allows for precise control of angular position, velocity, and acceleration. It consists of a motor coupled with a sensor for position feedback, typically a potentiometer or an encoder. This feedback enables the servo motor to accurately maintain the desired position of its output shaft without continuous input from an external source, making it ideal for applications requiring precise control over movement.
Servo motors are commonly used in various applications such as robotics, CNC machinery, remote control systems (like RC cars and planes), industrial automation, and more. They come in different sizes and power ratings depending on the specific application requirements.
