An AC servo motor is a high-performance motor used in closed-loop control systems. It provides:
Precise position, speed, and torque control
Fast response and acceleration
Feedback via encoders for accuracy
Itβs controlled by a servo drive (amplifier) that adjusts the motor's behavior in real time based on feedback.
