Exactly what is a Servo Motor?
A servo motor is a rotary actuator that’s designed for precise precision control. It consists of an Transmission Chain electric motor, a feedback device, and a controller. They could accommodate complex movement patterns and 
profiles better than any other type of engine. Although they are little 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 rely on an electric wall plug, instead of batteries like DC servo motors. While DC servo electric motor performance is dependent just on voltage, AC servo motors are dependent on both frequency and voltage. Due to the complexity of the energy supply, AC servo motors are designed for high surges, which is why they are frequently found in industrial machinery.
Why Choose an AC Servo Electric motor?
There are several benefits to choosing AC servo motors over DC servo motors. They provide more torque per weight, effectiveness, reliability and decreased radio frequency noise. And in the absence of a commutator, they might need less maintenance and also have a longer life expectancy. AC servo motors are found in a multitude of applications where position control is critical and are commonly used in robotics, semiconductor equipment, machine equipment, and aircrafts.
