An illustration from Small motors, transformers, electromagnets; a practical presentation of design and construction data for small motors, small low- and high-tension transformers, electromagnets, and induction coils, 1920, leaf 76 — he rotating field willbe of sine distribution. But since the sum of any number of sinewaves of any phase relation is also a sine wave, the total fluxenclosed in any turn will be a sine function of time. Therefore, ifthe maximum value of flux enclosed in each turn (which will bethe value when the… … MULTIPLY CONDUCTORS IN EACH SLOTT0RIN6 BY K2 =/5 TO RIN6 Fig. 27.
