Abstract: A damper winding for the rotors of large turbine generators to shield the rotor surface and windings from non-synchronous fluxes, or to reduce the negative resistance of the generator. The damper winding consists of longitudinal bars of low resistance material placed on the surface of the rotor over each tooth, including teeth formed on the pole face portions. The bars have longitudinal recesses to fit over the teeth and engage in the slot on each side for mechanical support of the bar, and the bars are in electrical contact with each other throughout their length to form a continuous conducting surface.
