A 20-pole, star-connected, three-phase alternator rotates at 300 r.p.m. The armature has 360 slots and 6 conductors per slot. The width of the coils is 5/6 of the pole pitch. If the maximum flux per pole, with a sinusoidal distribution, is 0.086 Wb, what will be the values of the emfs? phase and line? I need the procedure to get to that answer. Thank you

Explain the principles of starting a slotted pole by drawing a phase diagram of fluxes
