question

A 6-pole 3-phase 60-cycle alternator has 12 slots per pole and four conductors per slot. The winding is five-sixths pitch. There are 2,500,000 maxwells (= 0.025 weber) entering the armature from each north pole, and this flux is sinusoidally distributed along the air gap. The armature coils are all connected in series. The winding is Y-connected. Determine the open-circuit emf of the alternator.
