GENERATOR ROTOR WINDINGS

Rotor Tester


In a generator, alternator, or dynamo the armature windings generate the electric current. The armature can be on either the rotor or the stator. an excessive vibration of the generator rotor, induced by the heating effect of the field cur rent. As field current flows in the winding, the The AC current generated in the pilot generator windings is rectified and fed directly to the rotor windings to supply the excitation for the main machine.
