What is a Servo Motor and How it Works

Have you ever thought about how a robotic vehicle commonly used in a military application with bomb detention is controlled or how metal cutting and forming machines provide precise motion for milling, lathes and bending for metal fabrication or how an antenna positioning system control the precision in azimuth and elevation? As you will learn within this lesson, servo motor applications are most commonly used in closed loop systems where precise position control commonly found in industrial and commercial applications. Together with the recently RealPars published video, what is a Stepper Motor and How it Works, and this lesson, you will learn about motion control using different types of motors available, primarily stepper and servo motors. In this lesson we will discuss what a servo motor is and how it works, so let’s first determine what a servo motor is and examine some unique features of the types of a servo motor and its application.
