Stepper motor single step reaction.

[rais91]

Hello. I am newbie with simulink and system modeling. I have a model in simulink to make stepper single-step reaction. The thing is I can not bring it out. I mean that even with mechanical torque load equal to zero I have no angle output.
My variable parameters for the model are:

coilInductance=137e-3;
coilResistance=150;
stepAngle=1.8;
MaxVoltage=12;
Imax = MaxVoltage/coilResistance;
MaxFluxLinkage=Imax*coilInductance;

These are parameters that I know for sure for MSJC200B11 stepper motor of Sankyo production.
I left all other paraters' values as default.
Could you please tell me what am I doing wrong?

Thanks in advance.

Sorry for my broken English.

i run your model, to access non zero angle, you should determine a initial speed for your stepper motor block.
