A separately excited dc machine is coupled to a 50 Hz, three-phase, 4-pole induction machine as shown in figure. The dc machine is energized first and the machines rotate at 1600 rpm. Subsequently the induction machine is also connected to a 50 Hz, three-phase source, the phase sequence being consistent with the direction of rotation. In steady state DC Machine Induction machine 4 pole, 50Hz 50Hz, balanced three-phase supply (A) both machines act as generator (B) the dc machine acts as a generator, and the induction machine acts as a motor (C) the dc machine acts as a motor, and the induction machine acts as a generator (D) both machines act as motors A separately excited dc machine is coupled to a 50 Hz, three-phase, 4-pole induction machine as shown in figure.
