A blocked-rotor test was performed on a 5-hp, 220-V,...

A blocked-rotor test was performed on a $5-\mathrm{hp}, 220-\mathrm{V}$, four-pole, $60-\mathrm{Hz}$, three-phase induction motor. The following data were obtained: $V=48 \mathrm{~V}$, $I=18 \mathrm{~A}, P=610 \mathrm{~W}$. Calculate a. The equivalent stator resistance per phase $R_S$. b. The equivalent rotor resistance per phase $R_R$. c. The equivalent blocked-rotor reactance per phase $X_R$.
