A 4-pole, 36-slot, double-layer wound, three-phase induction motor has 10 turns per coil in the stator winding and a squirrel-cage rotor with 48 bars. The resistance and reactance of each bar are 20 μ and 2 m, respectively. Determine the equiv- alent rotor impedance as referred to the stator on a per-phase basis.
