What About Bandwidth?
The current loop takes the current reference and current feedback and outputs voltage to the motor. The position loop must have sufficient bandwidth to track the position One can not help but observe that once you add position feedback to a stepper motor, why not treat it like a genuine brushless motor? … Visit Document
Stepper Motor
If we command a stepper motor to move some specific number of steps, it rotates incrementally that many number of steps and stops. Because of this basic nature of a stepper motor, it is widely used in low cost, open loop position control systems. Open loop control means no feedback … Access This Document

Stepper motors
Steppers are generally commutated open loop, ie. the driver has no feedback on where the rotor actually is. Stepper motor systems must thus generally be over engineered, especially if the load inertia is high, or there is widely varying load, so that there is no possibility that the motor will lose … Get Content Here
