Abstract

In this paper the e.m.f. equation of an idealized synchronous generator, having a divided-winding-rotor, is derived. The equationis obtained in two alternative forms whereby the effect of shifting the resultant field around the rotor on the sinusoidal induced e.m.f. can be approached.
Shifting the resultant field axis from its original diraction results actually in considerable distortion in the resultant no – load m.m.f. distribution. This distortion affects the induced e.m.f. , as exhibited by the measured values on machine model . A comparative study of the results, obtained by applying the method of harmonic analysis to the different m.m.f. waveforms , leads to the interpretation of the variation in the measured e.m.f. Away from this method , however , a reliable measure is suggested for a quick prediction of this e.m.f. variation.
