A three-phase, wye-connected, 2300-V, 60-Hz, round-rotor synchronous motor has a syn- chronous reactance of 2 per phase and negligible armature resistance.
(a) If the motor takes a line current of 350 A operating at 0.8 power factor leading, calculate the excitation voltage and the power angle.
(b) If themotor is operating on loadwith a power angle of -20°, and the excitation is adjusted so that the excitation voltage is equal in magnitude to the terminal voltage, determine the armature current and the power factor of the motor.
hi can you help me to create a dc to 3 phase ac circuit which can exceed at any point: 50V and 20A and 400W maximum. The output should be variable from about 0 – 25V per phase, wi
We would like you to do an indepth study/research in the tradeoff between the filtering of the QR and the QR performance So it will be about filtering but more of an indepth for
