Introduction to AC Servo Motors
AC servo motors are a type of electric motor that is widely used in various industrial and automation applications. They offer high precision, high torque, and excellent speed control capabilities. Unlike traditional motors, AC servo motors can accurately control the position, speed, and torque of the motor shaft, making them ideal for applications that require precise motion control, such as robotics, CNC machines, packaging equipment, and semiconductor manufacturing.
The basic working principle of an AC servo motor is based on the interaction between the stator's rotating magnetic field and the rotor's magnetic field. The stator is supplied with an alternating current, which creates a rotating magnetic field. The rotor, which can be either a permanent - magnet or an induction type, follows the rotating magnetic field of the stator. The control system of the AC servo motor continuously monitors and adjusts the input current to the stator based on the feedback from sensors (such as encoders) to achieve the desired motion.
Now, let's take a look at the top 10 AC servo motor manufacturers in the world in 2026.
