Servo Motor Theory Of Operation A Quick Guide From Parker

A servo motor is one of the widely used variable speed drives in industrial production and process automation and building technology worldwide.

How does a servo motor work. From toys to home electronics to cars and airplanes. Shorter than 15ms moves it in the counter clockwise direction toward the 0 position and any longer than 15ms will turn the servo in a clockwise direction toward the 180 position. When a pulse is sent to a servo that is less than 15 ms the servo rotates to a position and holds its output shaft some number of degrees counterclockwise from the neutral point.

Servos are found in many places. It consists of a suitable motor position sensor and a sophisticated controller. A servo motor is an electrical device which can push or rotate an object with great precision.

A circuit associated with the servo uses the feedback signal and a commanded input position to move the motor to the correct position and hold it there. For example a 15ms pulse will make the motor turn to the 90 position. How does a servo motor work.

A servo motor is usually a reversible motor that has position feedback. It is just made up of simple motor which run through servo mechanism. In this video and blog post we will discuss what a servo motor is and how it worksservo motors are part of a closed loop system and are comprised of several parts namely a control circuit servo motor shaft potentiometer drive gears amplifier and either an encoder or resolver.

The position pulse must be repeated to instruct the servo to stay in position. Servos will not hold their position forever though. If you have a radio controlled model car airplane or helicopter you are using at least a few servos.

Servo motors can be characterized according the motor controlled by servomechanism ie. Servo motors or servos are self contained electric devices see figure 1 below that rotate or push parts of a machine with great precision. Although servo motors are not a specific class of motor they are intended and designed to use in motion control applications which require high accuracy positioning quick reversing and exceptional performance.

If dc motor is controlled using servomechanism it is called as dc servo motor. If you want to rotate and object at some specific angles or distance then you use servo motor. The servo motor expects to see a pulse every 20 milliseconds ms and the length of the pulse will determine how far the motor turns.
