Got a dumb question, I don't know which part of the Inductance and Resistance on the datasheet for the stepper motor I should consider to be the correct answer, to me it looks like there are 4 different answers for each...

 

The datasheet covers four different stepper motors. Which one are you asked for the parameters of?

nice, that's what I thought! I'm not sure honestly, here is the diagram:

 

RS 892-9299 is RS Components stock number. The manufacturer (Portescap) part number is 20M020D2B.

 

ahhh right, so it's the 12V bipolar one, meaning it would be 115.2ohms resistance and 52.8mH inductance?

 

You can also look at the supply voltage to stepper coils, and compare the arrangement of the windings to the information in the datasheet to determine which is which.

[Edit] But then you find a conflict. The stepper in the diagram has four coils, the bipolar motor has just two coils. ?????

damn, yeah that is confusing...I don't know which one it is then

 

Your circuit schematic shows wiring for a unipolar stepper motor. Perhaps the RS stock number shown is incorrect.

Thank you for your comment, I have emailed my professor to find out what I should do, probably need to switch my calculations to one of the unipolar motors once he advises
