NEMA 23 closed loop stepper motor as the controlled output returns to the control input in a certain way and exerts control influence on the input. The closed-loop control of the stepper motor uses position feedback or speed feedback to determine the phase conversion corresponding to the rotor position, which can greatly improve the performance of the stepping motor. These motors are also called Easy Servo Motors.
