What is a Servo Motor?
A servo engine is a rotary actuator that’s designed for specific precision control. It consists of a power motor, a feedback device, and a controller. They are able to accommodate complex movement patterns and profiles better than any various other type of engine. Although they are small in 
proportions they can pack a lot of power, and are extremely energy efficient.
There are two types of servo motors, AC servos and DC servos. The primary difference between the two motors is definitely their source of power. AC servo motors depend on an electric wall plug, rather than batteries like DC servo motors. While DC servo engine performance is dependent only on voltage, AC servo motors are reliant on both frequency and voltage. Due to the complexity of the power supply, AC servo motors can handle high surges, which explains why they are often found in industrial machinery.
Why Choose an AC Servo Motor?
There are several advantages to choosing AC servo motors over DC servo motors. They provide more agricultural Chain torque per weight, performance, reliability and decreased radio frequency sound. And in the absence of a commutator, they require less maintenance and have a longer life span. AC servo motors are found in a multitude of applications where placement control is crucial and are frequently used in robotics, semiconductor products, machine equipment, and aircrafts.
