A 440-V, 3-phase, 50-Hz, 37.3 kW, Y-connected induction motor has the following parameters: R1=0.1Q, X1=0.4N, R2' =0.15Q, X2' =0.440 Motor has stator core loss of 1250 W and rotational loss of 1000 W. It draws a no-load line current of 20 A at a p.f. of 0.09 (lag). When motor operates at a slip of 3%, calculate: (i) the input line current and p.f. (ii) the electromagnetic torque developed in N-m (iii) output power (iv) efficiency of the motor. Use exact equivalent circuit referred to primary,
