Answer Posted / ashokreddyreguri
Rotor of the alternator is given dc supply so constant
magnetic poles are formed.These constant magnetic poles
produce constant flux.The rotor of the alternator is
rotated by using prime mover,so constant poles are
rotated,so these rotating magnetic poles produce rotating
magnetic field.When this rotating magnetic field cuts three
phase stator conductors produces three phase supply.
