A 600 V, 6-pole, 3-phase, 50 Hz, star-connected synchronous motor has a resis tance and synchronous reactance of 0.4 Ω and 7 Ω respectively. It takes a current of 15 A at upf when operating with a certain field current. With the field current remaining constant, the load torque is increased until the motor draws a current of 50 A. Find the torque (gross) developed and the new power factor.
