What type of motor provides feedback about its speed, direction of rotation, and number of revolutions?

A servo motor is designed specifically to provide feedback about its speed, direction of rotation, and number of revolutions. It incorporates sensors that track its position and velocity, allowing for precise control and adjustments during operation. This feedback loop is essential in many applications where accurate movement control is critical, such as in robotics and CNC machinery.

In contrast, while step motors can achieve precise movement by dividing a full rotation into a set number of steps, they typically do not provide inherent feedback about their position or speed unless paired with an external encoder. DC motors are generally simple, providing rotational power but lacking integrated feedback mechanisms for monitoring speed or position. Induction motors, while effective for driving loads in many applications, do not provide feedback about rotation details and are typically more complex to control for precision tasks.

In summary, the feedback capabilities of servo motors make them the ideal choice for applications requiring detailed monitoring of movement, which is why this option is the correct answer.
