An AC servo motor is an electric motor that uses alternating current (AC) to produce precise motion control. Here's a concise overview of its working principle:https://www.yunwu-motor.com/servo-motor/

1. **Components**: It typically consists of a stator (the stationary part) and a rotor (the rotating part). The stator has windings that create a magnetic field when AC power is applied.

2. **Magnetic Fields**: The stator generates a rotating magnetic field, which induces movement in the rotor due to the interaction between the magnetic fields of the stator and rotor.

3. **Feedback Mechanism**: AC servo motors often include an encoder or resolver to provide feedback on the rotor's position, allowing for precise control of speed and position.

4. **Control System**: They are controlled by a servo drive, which adjusts the current to the motor based on feedback, enabling accurate positioning and speed control.

5. **Applications**: Commonly used in robotics, CNC machinery, and industrial automation due to their high efficiency, reliability, and ability to deliver precise motion.
