The method of connecting the shape of the flux distribution curve of a synchronous converter with the shape of its induced electromotive force wave, developed by the writer in his Atlantic City paper,∗ is here applied more specifically to the alternator, with an illustration taken from Mr. Bache-Wiig's Atlantic City paper on the "Application of Fractional Pitch Windings to Alternating-Current Generators". Parts of the explanation of the method are reproduced in a somewhat modified and condensed form for the benefit of those who did not read the other paper.
