Answer / capseee

When the prime mover rotates the rotor will rotate and cuts
the magnetic field line around it and hence power is
produced and the mechanical energy is transfer into
electrical energy.

Answer / shaikh

The key different between an alternator and a generator is
what spins and what is fixed. On a generator windings of
wire (the armature) spin inside a fixed magnetic field. On
an alternator, a magnetic field is spun inside of windings
of wire called a stator to generate the electricity.

Answer / kumar

for example take gen set in gen set alternator is coupled
with diesel engine .so whenever engine rotate .shaft of the
engine is coupled with alternator rotor .in alt stator has
permanent magnet so at time of rotor rotating its cut the
magnetic flux therefore Mechanical energy converted into
electrical energy .
