2PHASE 0.7OHM 2.0mH NEMA23 4.2A 2.2NM CLOSE LOOP STEPPER MOTOR FOR
For Textile Machine
This enables servo motors to be used with gearboxes to deliver much
higher torque at useful speeds. They also deliver more consistent
torque across the speed range of the motor. Unlike stepper motors,
they do not have holding torque per se.

4. Advantages of close loop stepper motor:
Advantages of a Closed-Loop Stepper Motor System
A closed-loop step motor system combines the advantages of servo
motor and stepper motor technologies. Functionally, a closed-loop
stepper motor system will run much more smoothly and with less
resistance than a standard stepper motor setup. Since a closed-loop
system provides feedback and control as well as short transient and
free oscillation times, the closed-loop system will not lose or
gain steps.
A closed-loop stepper motor system may be the best option when the
application requires improved energy efficiency and smoothness of
operation, especially at high loads. In addition, a closed-loop
stepper system has the advantage over servo motor systems of higher
torque at low RPMs. Additional benefits include short transient
times, less packaging, accurate/correct positioning using feedback
from encoders integrated into the motor(s) to the controller, and
comparatively low prices.
