What type of motors provide feedback about their operational status?

Servo motors are designed to provide precise control of angular position, velocity, and acceleration and include built-in feedback systems that monitor their operational status. This feedback typically comes from sensors such as encoders or resolvers that relay information about the position, speed, and torque back to the control system, enabling real-time adjustments and maintaining accuracy in automated applications.

This feedback mechanism is crucial in various robotic and CNC applications where precise movement and positioning are essential. Servo motors can respond effectively to changes in load or operational conditions, making them ideal for applications that require high precision and responsiveness.

In contrast, the other types of motors do not typically offer integrated feedback mechanisms. Universal motors and induction motors are generally used in applications where simple ON/OFF control is sufficient, while step motors operate in discrete steps and can be precisely controlled without feedback, but they do not inherently provide status feedback in the same way that servo motors do.
