INTRODUCTION TO SERVO MOTOR

Servo motor is a rotary actuator which is used for precise control of angular, linear position and acceleration. It is used to rotate or push any device with great precision.

Servo motor is made up of DC motor which is controlled by potentiometer and gears.

Its basic principle is PWM; it means the angle of rotation is controlled by duration of pulse applied on it.

The motor is controlled by the electrical signals; it can be analog or digital.

Servo motors are used in many applications like robotics, CNC, toys, home appliances, car and many more.
