Abstract
Relationships between shaft signals and eccentricities of salient-pole synchronous machines are studied. The magnitude and the thickness of shaft-signal loci reflect steady and dynamic eccentricities. Harmonic components of shaft signals closely relate to shorted field coils. Thr eshold records can be used for indications of changes in eccentricitie s and shorted field coils. Extensive experimental work agrees with the theoretical predictions.
