Stepper Motor Transfer Function

[SK0480]

How do I model the stepper motor.. I know how to derive the transfer function of the servo motor but need to know how can I get the transfer function of the steppr motor.

I searched to find some resources on calculating the transfer function and came across the following articles:

I hope these help get you pointed in the right direction!
