EAD ROOM 135 HP (output HP), 3,300 V, 60Hz, three-phase wye connected induction motor has a synchronous ! speed of 600 rpm. The full-load slip is 3% and the full-load pf is 50%. Mechanical losses = 2, 400W; Iron loss = 3000 W Stator copper loss = 1,200W; Calculate: (a) line current; (6) RCL ; & (c) full-load efficiency. H] A 400V, 60Hz, 6- pote, delta connected, 3-phase IM consumes 45 kW with a line current of 75A and tuns at a 5% slip. Friction & windage loss = 900W Stator iron loss = 1000W and tesistance between 2 stator terminals is 0.12.2. Calculate, (a) torque developed at the shaft, and (b) full-load efficiency.
