What is a Servo Motor?
A servo electric motor is a rotary actuator that is designed for specific precision control. It consists of an electric motor, a feedback device, and a controller. They are able to accommodate complex movement patterns and profiles much better than any other type of motor. Auto Chain 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 usually their source of power. AC servo motors rely on an electric outlet, instead of 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 energy supply, AC servo motors are designed for high surges, which explains why they are often 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 offer more torque per weight, performance, reliability and reduced radio frequency sound. And in the lack of a commutator, they require less maintenance and also have a longer life span. AC servo motors are used in a multitude of applications where position control is critical and are frequently used in robotics, semiconductor apparatus, machine tools, and aircrafts.
