From manufacturing and robotics to aerospace and healthcare, servo motors have revolutionized the way machines and processes are controlled. In this article, we will explore the fascinating world of servo motors, their applications, and the latest advancements that make them indispensable in modern technology.

 Understanding Servo Motors

A servo motor is a specialized electric motor designed to provide precise control of angular or linear position, velocity, and acceleration. Unlike conventional motors, servo motors are equipped with feedback mechanisms, such as encoders or resolvers, which continuously monitor and report the motor's current position to a controller. This feedback loop enables the controller to make real-time adjustments, ensuring the motor moves with incredible accuracy.

Applications of Servo Motors
