Really,
I think it just won't help, but my teacher wanted up to get a transfer function ofr the control system we choose. I choose stepper, but I don't think transfer function would help. appart, which would be the input state for the transfer function??
Speed versus voltage ?? No, voltage applies to several windings.
Torque versus voltage?? Very hard to measure, and not very usefull
I think I will just make a control circuit, which I'm just finishing, and document all the stuff, as I really don't know how to find and use a transfer function for steppers..
