Answer / jignesh patel

50 Hz.
stator winding and rotor winding has rotating field so it
has 50Hz freq.
There is a commutator which is converted ac voltage in to
dc.

Answer / ashok

p=4;
ns=1500;
we know that
ns=120f/p;
f=ns*p/120;
f=50hz

Answer / jenjen

The question is not clear. It does not clearly mention whihc
frequency it refers to.

If we consider the output d/c voltage, its frequency should
be zero; however, the frequency of the generated voltage in
the armature will be:

1500*4
f= ------ Hz = 50Hz.
120

Answer / kj

The generator will put out a DC voltage with a slight
ripple. The ripple frequency will depend on the number of
coils on the armature and the number of segments on the
commutator.
It will not have a frequency similar to AC.
