Q. A wye-connected, three-phase, 50-Hz, six-pole synchronous alternator develops a voltage of 1000 V rms between the lines when the rotor dc field current is 3A. If this alternator is to generate 60-Hz voltages, find the new synchronous speed, and calculate the new terminal voltage for the same field current.
A 200-V dc shunt motor has a field resistance of 200 and an armature resistance of 0.5 . On no load, the machine operates with full field flux at a speed of 1000 r/min with an a
