question

The following data are for a three-phase 13,800-V wye-connected60,000-kVA 60-Hz synchronous generator: P = 2; stator slots = 36, stator coils = 36, turns in each stator coil= 2 Stator coil pitch = (2/3), rotor slots = 28 Spacing between rotor slots = [1 / (37)] of circumferenceRotor coils = 14 Turns in each rotor coil = 15 I.D. of stator iron = 0.948 m O.D. of rotor iron = 0.865 m Net axial length of stator iron = 3.365 m, stator coil connectionis two-circuit (a = 2) series rotor-coil connection. Assume thatg_e= 1.08 g and calculate the unsaturated self-inductanceof the field winding based on the fundamentalcomponent of the air-gap flux.
