All servo motors:

A) operate in the closed-loop mode.
B) operate in the open-loop mode.
C) operate without feedback.
D) operate in the open-loop mode and without feedback.

Servo Motors

A type of motor that facilitates precise control of angular or linear position, velocity, and acceleration.

Closed-loop Mode

Closed-loop Mode operation refers to a control system configuration where the output is continuously monitored and feedback is used to adjust the control action to achieve desired performance.

Open-loop Mode

A control system mode where the output is not fed back to the input for decision making, meaning actions are taken without considering the outcome.
