Servo Motor are also called Control motors. They are used in feedback control systems as output actuators and does not use for continuous energy conversion. The principle of the Servomotor is similar to that of the other electromagnetic motor, but the construction and the operation are different. Their power rating varies from a fraction of a watt to a few hundred watts. The rotor inertia of the motors is low and have a high speed of response.

The servo motor has a rotation detector encoder mounted on the back shaft side of the motor to detect the position and speed of the rotor. This enables high resolution, high response positioning operation. The load is driven through the transfer mechanism such as the coupling.

The encoder is a sensor for detecting the speed and position of the motor. Light from the light-emitting diode LED passes through a position detection pattern on the slit disk and is read by the light-receiving element. Dozens of photo transistors are integrated in the light-receiving element. All of the patterns for absolute position detection depends on the rotation angle of the encoder.

The CPU is mounted on the encoder for analysis of the absolute position detection patterns. The current position data is transmitted to the servo driver via serial transmission. A pulse signal that is externally applied when it is the pulse input type and the rotation detected by the servo motor encoder, are counted and the difference deviation is outputted to the speed control unit.

This counter is referred to as the deviation counter. During motor rotation, an accumulated pulse positioning deviation is generated in the deviation counter and is controlled so as to go to zero. The position holding by servo control function for holding the current position is achieved with a position loop deviation counter.

The servo motor is composed of three elements: the motor, the encoder and the driver. The servo motor always detects the motor condition from the encoder position and speed information. If the motor should come to a standstill, the servo motor outputs an alarm signal to the controller for abnormality detection.

The servo motor must adjust the control system parameters to match the rigidity of the mechanism and the load conditions, though in recent years, real time auto-tuning has made this adjustment easy.

If you want to rotate an object at some specific angles or distance, then you use a servo motor. For this tutorial, we will be discussing only about the DC servo motor working. A servo motor usually comes with a gear arrangement that allows us to get a very high torque servo motor in small and lightweight packages. Due to these features, they are being used in many applications like toy car, RC helicopters and planes, Robotics, etc. It is a closed-loop system where it uses a positive feedback system to control motion and the final position of the shaft.

To choose a motor is the hardest task, based on design criteria such as cost, torque, acceleration, positional accuracy, power and much more. There are many types of motors like DC, Servo, and Stepper available for different types of application. But, Servo motors come with fast functioning, high torque , and accurate rotation. Yes, Stepper Motors are a high-performance alternative of the servo. But to setup a Stepper is more complicated than a Servo Motor.

Servo Motor – Types and Working Principle

Servo motor is revolving or linear motion actuator, that allows the precisely control of its linear velocity, acceleration or angular position. This motor is available in market with coupled sensor for feedback control. This motor is control with sophisticated controller or a special kind of module is designed for controlling this motion.

Servo Motor construction working and control

The servo motor is most commonly used for high technology devices in the industrial applications like automation technology. It is a self contained electrical device, that rotates parts of machine with high efficiency and great precision. Moreover the output shaft of this motor can be moved to a particular angle.

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

A type of servomotor that uses AC electrical input in order to produce mechanical output in the form of precise angular velocity is known as AC servo motor. AC servomotors are basically two-phase induction motors with certain exceptions in designing features. The output power achieved from ac servomotor ranges between some watt to a few hundred watts. While the operating frequency range is between 50 to Hz. It provides closed-loop control to the feedback system as here the use of a type of encoder provides feedback regarding speed and position.
