AC servo motor

Exactly what is a Servo Motor?
A servo motor is a rotary actuator that is designed for exact precision control. It includes a power motor, a feedback device, and a controller. They are able to accommodate complex movement patterns and profiles much better than any various other type of motor. Although they are small in proportions they can pack a whole lot of power, and are extremely energy efficient.

There are two types of servo motors, AC servos and DC servos. The main difference between your two motors is certainly their way to obtain power. AC servo motors rely on an electric outlet, rather than batteries like DC servo motors. While DC servo motor performance is dependent only on voltage, AC servo motors are dependent on both frequency and voltage. Because of the complexity of the power supply, AC servo motors are designed for high surges, which is why they are often used 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 torque per weight, efficiency, reliability and decreased radio frequency sound. And in the absence of a commutator, they require less maintenance and also have a longer life expectancy. AC servo motors are used in a wide variety of applications where placement control is critical and are frequently used in Auto Chain robotics, semiconductor equipment, machine tools, and aircrafts.
