A 2200-V, 1000-hp, three-phase, 60-Hz, 16-pole, wye-connected, wound-rotor induction motor is connected to a 2200-V, three-phase, 60-Hz bus that is supplied by synchronous generators. The per-phase equivalent circuit of has the following parameters: R1 = 0.1 = R 2, Xl1 = 0.625 = X l2, and Xm = 20 .Ifthe machine is driven at a speed of 459 r/min to act as a generator of real power, find the rotor current referred to the stator and the real and reactive power outputs of the induction machine.
Q. Show Applications for Synchronous Motors? With constant-speed operation, power factor control, and high operating efficiency, three-phase synchronous motors are employed in
A 500KVA, 6 pole, 500v, 3 phase, wye-connected synchronous generator has a synchronous impedance of 0.1 + j1.5 ohms per phase. If the generator is driven at 1000 r.p.m., what is th
what is emitter efficiency
