induction motor? Given question:
A 3-phase, 4-pole, wound-rotor induction motor having a rating of A hp, B r/min, C kV, D Hz, drives a belt conveyor. The rotor is connected in wye and the nominal open-circuit voltage between the slip rings is E V. Calculate the rotor winding resistance per phase.

This Is just an example question from the textbook I found. I just want to know the formulas and steps to find that rotor winding resistance per phase. Links to a website may be helpful :)

Thank you~!
