What is a key feature of a servo motor?

A key feature of a servo motor is its ability to modulate its operations based on feedback. This capability allows servo motors to achieve precise control of position, speed, and torque, making them ideal for applications that require exact movements. The feedback mechanism typically involves sensors that monitor the motor's current position and send this information back to the controller. If there is a discrepancy between the desired position and the actual position, the controller adjusts the motor's movements accordingly to correct any errors.

This feedback system is fundamental to the performance of servo motors, distinguishing them from other types of motors that may not have this adaptive capability. Thus, the feedback loop enables high accuracy and responsiveness in various applications, from robotics to automated manufacturing processes.
