Q22: Consider the core shown in the figure below. The mean length of magnetic path is 40 cm and the effective area of cross section of the core is 9cm². The number of turns in the exciting coil is 1000 When a sinusoidal voltage of 220V(rms) at frequency of 50 Hz is applied to the exciting coil, the hysteresis loss is found to be 40 W and the eddy current loss 10W. The Steinmetz exponent for the magnetic material may be assumed to remain constant at a value of 1.6. Determine the hysteresis and eddy-current losses when a triangular voltage v(t) shown in the figure below is applied to the exciting coil. Assume that the voltage drop in the resistance of the exciting coil is negligible. V(t) Area A Core v(t) 220 V O -220 V T=1/200 sec. Q23: A 4-pole DC armature wave winding has 320 conductors. What flux per pole is necessary to generate 340 V when rotating at 1500 rpm? Q22: Consider the core shown in the figure below.
