The AC servo motor is most suitable for controlling what type of loads?

The AC servo motor is particularly well-suited for controlling lighter loads due to its precise control capabilities and fast response times. These motors are designed to deliver accurate positioning and velocity control, making them ideal for applications where weight optimization is crucial, such as in robotics, CNC machinery, and automation systems.

While AC servo motors can handle a range of loads, their strength lies in precision control rather than sheer power, which makes them less ideal for heavy or high torque loads compared to other motor types like DC servo motors or stepper motors, which can provide more torque at lower speeds. Therefore, for applications that require lightweight load handling with high precision, AC servo motors are the preferred choice.
