What is a Servo Motor?
A servo engine is a rotary actuator that’s designed for exact precision control. It includes an electric motor, a feedback gadget, and a controller. They are able to accommodate complex movement patterns and profiles better than any additional type of motor. Although they are small in size they can pack a lot of power, and so are extremely energy efficient.
There are two types of servo motors, AC servos and DC servos. The main difference between the two motors is usually their way to obtain power. AC servo motors depend on an electric wall plug, rather than batteries like DC servo motors. While DC servo electric motor performance is dependent just on voltage, AC servo motors are reliant on both frequency and voltage. Because of the complexity of the power supply, AC servo motors can handle high surges, which explains why they are frequently used in industrial machinery.
Why Choose an AC Servo Motor?
There are several advantages to choosing AC servo motors more than DC servo motors. They offer more torque per weight, effectiveness, reliability and Transmission Chain decreased radio frequency noise. And in the absence of a commutator, they might need less maintenance and have a longer life span. AC servo motors are 
found in a multitude of applications where placement control is critical and are frequently used in robotics, semiconductor products, machine tools, and aircrafts.
