Q3 A 50-kW, 440-V, 50-Hz, six-pole induction motor has a slip of 6 percent when operating at full-load conditions. At full-load conditions, the friction and windage losses are 300 W, and the core losses are 600-W. Find the following values for full-load conditions: (a) The shaft speed nm (b) The developed mechanical power (Pconv) in watts (4 Marks) (4 Marks) (4 Marks) (4 Marks) (c) The load torque (Tload) in newton-meters (d) The induced torque (Tind) in newton-meters (e) The rotor frequency in hertz Under what conditions, this induction motor will start working as an induction generator? Explain using torque speed/slip characteristics and different modes of operation. Total (4 Marks) (5 marks) (25 Marks)
