What defines a servo motor?

The essence of a servo motor lies in its ability to provide precise control over its motion, which is accomplished through feedback systems. Specifically, a servo motor is characterized by its integration of a feedback loop that continuously monitors the motor's position, speed, and direction. This feedback allows the system to make real-time adjustments to ensure that the motor operates as intended, achieving high levels of precision and accuracy in positioning.

In industrial applications, this capability is crucial, as it enables the motor to perform tasks that require exact positioning and smooth operation, such as in robotics or CNC machinery. The ability of the servo motor to respond dynamically to changes in its operational parameters makes it highly reliable and versatile in automated environments.

Other options describe different types of motors or systems that do not encapsulate the unique characteristics of a servo motor, such as a motor responding solely to predefined angles without feedback, or systems that lack the specific control features associated with servo motors. This distinction in functionality highlights why the ability to provide feedback on various operating conditions is the defining feature of a servo motor.
