Servo Motors

A servo motor is an automatic device that uses error-sensing feedback to correct the performance of a mechanism. The term correctly applies only to systems where the feedback or error-correction signals help control mechanical position or other parameters. For example, an automotive power window control is not a servomechanism, as there is no automatic feedback that controls position—the operator does this by observation. By contrast the car's cruise control uses closed loop feedback, which classifies it as a servomechanism. A servomechanism may or may not use a servo motor. For example, a household furnace controlled by a thermostat is a servomechanism, yet there is no motor being controlled directly by the servomechanism. A common type of servo provides position control. Servo motors are commonly electrical or partially electronic in nature, using an electric motor as the primary means of creating mechanical force. Other types of Servo motors use hydraulics, pneumatics, or magnetic principles. Usually, Servo motors operate on the principle of negative feedback, where the control input is compared to the actual position of the mechanical system as measured by some sort of transducer at the output. Any difference between the actual and wanted values (an "error signal") is amplified and used to drive the system in the direction necessary to reduce or eliminate the error. This procedure is one widely used application of control theory. Servomechanisms were first used in military fire-control and marine navigation equipment. Today servomechanisms are used in automatic machine tools, satellite-tracking antennas, remote control airplanes, automatic navigation systems on boats and planes, and antiaircraft-gun control systems. Other examples are fly-by-wire systems in aircraft which use servo motors to actuate the aircraft's control surfaces, and radio-controlled models which use RC servos for the same purpose. Many autofocus cameras also use a servomechanism to accurately move the lens, and thus adjust the focus. A modern hard disk drive has a magnetic Servo Motor system with sub-micrometre positioning accuracy. Typical servos give a rotary (angular) output. Linear types are common as well, using a screw thread or a linear motor to give linear motion. Another device commonly referred to as a servo motor is used in automobiles to amplify the steering or braking force applied by the driver. However, these devices are not true Servo Motors, but rather mechanical amplifiers. In industrial machines, Servo Motors are used to perform complex motion.
