Answer / avd
In AC motor load current flows in stator and causes heating
of stator. Hence to cool it down fan is provided which
cools the body. To increase area fins or plates are there
on body.
In DC motor load current flows through armature, causes
heat generation in armature. To take out the heat you need
to cooldown armature. Stator cooling is not required, hence
plan body is okay.
