Amortisseur Windings

[wbd]

Hello,
How can you tell by looking at a generator if there are amortisseur windings? These are open, small hydro powered generators.

Thanks in advance

The amortisseur windings of a synchronous AC generator are the conductors embedded in the pole faces of the rotor. They are connected together at both ends of the poles by end rings or end plates. Their function is to dampen waveform distortion during load changes.

Suggestion: Typically, all salient type of synchronous machines have the amortisseur to be able to start them.
