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
