engineering recuitment GATE EE 2023-24 Test Series Electrical Machines Three Phase Induction Motor Induction Motor Slip
A separately excited dc machine is coupled to a 50Hz, three phase, 4-pole induction machine. The dc machine is energized first and the machine 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
1
both machines act as generators
2
the dc machine acts as a generator and the induction machine acts a motor
3
the dc machine acts as a motor and the induction machine acts a generator
4
both machines act as motors
