What is a AC servo motor?

An AC servo motor (British: AC servo motor) is one of the actuators that convert electrical command signals from a host controller etc. into physical movement. For example, the motion of moving a robot arm to a specified position. The servo of the servo motor has the meaning of moving faithfully as instructed, and the AC servo motor can achieve accurate rotational position, rotational speed, and rotational force through electrical control. Motors include DC motors, AC motors, pulse motors, etc., but AC servo motors are classified as AC motors, and most of the motors for position and speed control currently used in the field of FA (factory automation) are AC servo motors.
