Answer to Question #117819 in Electrical Engineering for Sachin Kumar

Question

A 415 star-connected, 3-phase,4-pole synchronous generator has 36 slots carrying double layer 3-phase windings formed through uniformly distributed coils each short-pitched by one slot. The diameter at the air gap is 20 cm and the effective axial length is 60 cm. The rotor driven at 1500 rpm is excited to result in a sinusoidally varying air gap flux density distribution in space with a peak value of 0.5 T.Calculate the number of series turns per phase to generate rated no-load voltage.
