Q1/ A three phase, 500 kVA, 6600 V, 50 Hz, 6 pole, star connected synchronous motor has synchronous impedance of J 70 ohm per phase at its normal rating, the motor is excited to give unity power factor at the input terminals. Find a) The rated current and power factor. b) The emf behind the synchronous impedance. c) The developed torque. d) The pull out torque. e) The increase in excitation which will just permit an increase of 30% of rated torque before pulling out of synchronism.
