An AC servo motor is a type of electric motor that uses alternating current to produce precise control of angular position, speed, and acceleration. It typically consists of a stator and a rotor, where the stator generates a rotating magnetic field that drives the rotor. This motor is widely used in applications requiring high performance and accuracy, such as robotics and CNC machines. AC servo motors are often paired with a servo drive that regulates the motor's speed and position based on feedback from sensors. This closed-loop system allows for real-time adjustments, ensuring that the motor operates efficiently and accurately. Their ability to maintain high torque at various speeds makes them ideal for dynamic applications.
