Example 34.38. A 400 V, 50-Hz, 6-pole, A-connected, 3-4 induction motor consumes 45 kW with a line current of 75 A and runs at a slip of 3%. If stator iron loss is 1200 kW, windage and fricition loss is 900 W and resistance between two stator terminals is 0.12 2, calculate (i) power supplied to the rotor P2 (ii) rotor Cu loss P (iii) power supplied to load Pout (iv) efficiency and (v) shaft torque developed. 45 x 1000
