Introduction to Servo Motors

A servo motor is a self contained electrical device used as a control system to control the position of an object’s rotation. A servo motor combines the use of a mechanical motor along with an electrical sensor to move a shaft. Servo motors can utilize feedback from the shaft to rotate it to an angle with a certain velocity. Servo motors with closed-loop feedback use positional feedback to control the motion and the rotational speed. Servo motors can be operated with both AC and DC electrical control. Servo motors are widely available in both commercial and industrial applications. Some common applications for servo motors consist of robotics, powertools, airplanes, and computers.
