Single-step stepper motor reaction.

Hello. I'm very new to simulink.

I saw two steppermotor models.

Both of them have demo systems. Both are from different libraries.

Here is my question: How can I use those models to make a single-step reaction for stepper motor?

I tried to change signal builder's signals but this did not give any result for me. More over I tried to generate phase voltages for single-step using signal builder and Controlled Voltage Sources. That did not do the thing either - I have voltages changing as I need, but phase currents are not changing from zero even when I set phase resistance to something like 0.5 Ohm. (for your interest I'm trying to model MSJC200B11 stepper motor. It has 150 Ohm of phase resistance and about 137e-3 of phase inductance. Surely I changed it from unipolar to bipolar by disconnecting of middle wire of the coils).

Thanks in advance.

Sorry for my broken English.

In Simscape Electrical there are some good examples to start with:

• Stepper Motor with Control
• Stepper Motor Averaged Mode
• Unipolar Stepper Motor with Control
• Unipolar Stepper Motor Averaged Mode
