Winding Pitch Ratios of Synchronous Generators

[frank93]

Other then the effects on harmonic current, is there any significant differences in performance or any other characteristics due to the change of the winding pitch ratio of a synchronous generators?

In other words will a synchronous generator with a 2/3 winding pitch ratio perform differently then a generator with a 3/4 winding pitch ratio?

Suggestion: The smaller winding pitch (coil-span) has technical advantages in the reduction of overhang copper.
