The shaft of a three-phase synchronous generator is rotating at 3000 RPM synchronous speed. This generator is supplying a load of 40 KW, 0.8 PF lagging, with an efficiency of 75 %. The copper losses are neglected. Calculate the sum PF&W + Pcore + Pstray Answer: The sum PF&W + Pcore + Pstray is: A 2300 V, 400 HP, 50 Hz, eight-pole, 0.85 Leading PF, Y-connected synchronous motor is having a negligible armature resistance, and a synchronous reactance of 15 2. This motor is operating at EA = 1841 Volts, and 8 = -25°. If the flux is increased by 10 % while the power is kept constant, find the new armature current and the new power factor of the motor.
