Abstract: Direct Current (DC) motors are widely used because they come in many shapes and sizes, so their application is quite easy and flexible, and they have high reliability and low cost. Speed and position control are required in industrial applications, robot manipulators and home appliances. Because of the accurate and efficient tuning of parameters for PID controllers, they have become very important for the process industries. They have a simple structure, good stability, and high reliability. Electric motors are used in many homes, industrial, military, and other systems. Electric motors have properties that depend on the type of motor selected for the appropriate application. The performance of the motor depends on the system of which it is part. The appropriate design must be chosen for each part to obtain the best performance and the highest efficiency. Elevators, jacks, cars, trains, printers, home appliances, industrial, civil, and military systems, as well as robots, all use electric motors. It can be used in different applications, such as underwater welding, and in other places that are dangerous to humans, such as the operation of mine-removal, explosive dismantling, and others. The aim of this research is to review papers related to various servo motors and also the comparison between the different motors has been discussed in detail
