A three phase motor is connected to a 60Hz electrical source. The motor spins at 600rpm. Find the number of poles in the machine. The output of the above motor is connected to the input of a generator.
A three-phase, 5kVA, 208 V, four-pole, 60Hz, Y-connected synchronous generator has negligible stator winding resistance and a synchronous reactance of 8 ohms per phase at rated terminal voltage.
The input power to the geenrator is 100hp. When the generator is operating at rated values and unity power factor, the generator is 80% efficient. a.) Find the generator speed in rpm and rad/sec. b.) Find the mechanical torque supplied to the gener
