عندي سوالين ارجو ان اجد لهم حل ضروري
A three-phase, six-pulse controlled rectifier converter is connected to a three-phase 480-V, 60-Hz source. The load consists of a 500 V dc source having an internal resistance of 2 Ω. Calculate the power supplied to the load for the triggering delays of
A DC motor is connected to a 208 V, three-phase, 60 Hz line using a three-phase bridge converter as shown in the figure below. The DC motor has the following parameters Laf = 1.8 H, Vf = 240 V, Rf = 240 Ω, Ra = 4 mΩ, Lf = 120 H. if the triggering angle is 27.13o and the full load armature current is 2500, calculate:
(1) The voltage Vd.
(2) The speed of the motor under rated full-load conditions.
(3) The rated power in hp.
