Damper winding is used in pole shoes of alternator. It
consists of short circuited copper bars. The question may
arise then how do they have potential difference when they
are short circuited ? The concept is of mutual induction.
Also they are used for the starting of the generator, and in
case of fluctuations of the rotor (called huntng of the
rotor) they will damp the hunting, that's why the name goes
damper winding.
