stepper motor encoder

A stepper motor encoder is a device mounted on a stepper motor that provides a closed-loop feedback signal by tracking the speed and/or position of the motor shaft. ‌This encoder ensures precise control and positioning of the stepper motor by monitoring motor parameters such as speed, distance, revolutions per minute (RPM), and position. The stepper motor itself is an open-loop system, which means that it does not require sensors to feed information back to the controller, so it may experience loss of steps in some cases.
