AC Servo Motor

Our AC servo motor are used in applications that require closed loop and precise or instantaneous positioning and speed control, such as robotic systems, computer numerical control or CNC equipment, and industrial automation processes. Conventional AC motors differ from AC servo motors because AC servo motor incorporate a feedback system for controlling the motor's motion.
Our AC servo motor and servo drives combine the precision of a custom solution with the quick delivery and cost-efficiency of a catalog product. For specialized motion control needs, contact our engineering team to tailor a solution for your machine design. Whether you choose a standard product or a customized option, we’ll help you find the perfect motion control solution to meet your exact requirements.

The core components of an AC servo motor include:

Stator: The stator is the component of the motor that does not rotate and comprises the coils that create the rotating magnetic field given electricity from the source. The speed of operation of the AC servo motor depends on the number of poles of the stator.
Rotor: The rotor is the rotating component of the motor with a permanent magnet or a field, which is usually formed of electromagnets. The working of the AC servo motor is based on the idea that the rotor creates torque through interaction with the stator's magnetic field.
Encoder/Resolver: This is one of the crucial features that update the position of the AC servo motor, its velocity, and direction. The encoder or resolver supplies signals to the motor controller, which helps the motor control gain accurate control.
Housing: Though the entire assembly is enclosed, it is designed in such a way that internal parts of the assembly are well protected from the environment and mechanical force.
Bearings: Bearings are used to support the shaft, especially the rotor, and they provide low friction for rotational movement.
Cooling Mechanism: In some cases, depending on the kind of motor used and where it is applied, it may contain a cooling system to reduce the system heat produced by the AC servo motor.

Characteristics of AC Servo Motor

High Torque at Low Speed: AC servo motors are able to develop high torque throughout the low-speed range and, therefore, will not degrade inside momentum and constantly needed force.
Precision and Accuracy: The feedback mechanism enables precise control of the motor position speed and acceleration, reducing errors and variance.
Smooth Operation: Since the sinusoidal back EMF and the closed loop system are used, the operation is smooth, perfect, and vibration-free.
Wide Speed Range: AC servo motors are usable at high speeds, and performance does not degrade over low speeds; hence, they are useful in various applications.
Quick Response: A closed-loop feedback system enables one to control the motor in real time, hence enabling a very fast response to the motion.
Low Inertia: AC servo motors normally have low rotor inertia, which means they must accelerate and decelerate quickly, which is so relevant in dynamic types of applications.

Advantages of AC Servo Motor:

High Efficiency: AC servo motors are developed to remain highly efficient and to transform a vast amount of electrical and mechanical energy, thus consuming less energy.
Precise Control: A closed-loop feedback system also makes it possible to control position, speed, and acceleration, and as a result, the performance is well controlled.
Versatility: AC servo motors can be applied to almost all fields, such as robotics, CNC machines, appliances, etc. because they have high applicability and a large speed range.
Reliability: AC servo motors are very dependable because of the rigid structure and sophisticated control circuits, which are easy to maintain and have a long service life.
