A large 3-phase, 400 V, 60 Hz squirrel-cage induction motor draws a current of 385 A and a total active power of 2344 kW when operating at full-load. The corresponding speed is accurately measured to be 709.2 rpm. The stator is connected in wye and the resistance between two stator terminals is 0.10 Ω. The total iron losses are 23.4 kW and the windage and friction losses are 12 kW. Calculate the active power supplied to the rotor. (3 marks) Choose an appropriate motor's slip and compute the total copper losses in the rotor.
