The working principle of closed-loop stepper motor is based on feedback control. Encoders or other position sensors constantly monitor the position of the motor and feed the actual position information back to the motor controller. The controller compares the target position and if an error is detected, it adjusts the motor's control signal accordingly to correct the error and move the motor to the correct position.
