The main parameters o f the exciter and main generator are tabulated in Table 1．Fig．6 and Fig．7 illustrate the exciting current waveform s of the exciter and main generator，respectively．Due to the effect of rectification and armature reaction，the sixth harmonic comes up in the exciting current．However， thanks to the filtering function from the inductance inherent in the exciting windings，the exciting current at a stable state has little fluctuation．In Fig．8 and 9 the phase voltages and currents o f the main generator are pictured， respectively．With boosting of the exciting current，the voltage and current of the main generator are built up gradually to the rated values with sinusoid waveforms of 50Hz。Fig．10 and 11 manifest the phase voltage and current waveforms of the exciter．Owing to the effect of switching of the diode and filtering from the loop inductance，serious distortion in the phase voltage and current waveforms of the exciter happens．
Fig．12— 15 illustrate the phase current and exciting current waveforms of the exciter at several operation conditions．According to the figures，it’s easy to find that the exciting current waveforms change obviously when a fault of the rotor occurs and the waveforms at various kinds of faults are different．Knowledge of the above characters is very important and signi ficant for the real—time diagnosis of the faults in the rotor of a brushless AC generator with a rotary rectifier．
