Integrated Closed-loop stepper motor is a low-cost servo solution, which combines advantages of stepper motor and FOC servo control technology.   Comparing to the open-loop stepper motor, it has the advantages of servo control, such as smooth operation with no loss step, no resonance, low noise, high efficiency and high acceleration etc.  Comparing to servo motors, it has advantages such as stable low speed operation, high torque at low speed, short transient time, low cost and small size etc.
