Effects of structural design of pole arc offset in a salient pole generator to obtaining sinusoidal voltages with the least harmonics

Abstract

In this study, an optimum design in which pole arc offset has changed for a salient pole generator which able to give the best sinusoidal voltages have been made. Once electromagnetic analysis of the studied generator is being made, performance over producing better sinusoidal voltages rather than the shape without salient pole arc offset have been seen. Static magnetic and analytic designing of the dealt with salient pole generator have been made, and pole arc offset's effect to the induced voltages has been commented. If the offset raises by such analysis like changing pole arc offset of the generator at full load state, the obtained generator voltages approach to more accurate sinusoidal wave form with eliminating the harmonics.
