The brushless excitation system

Electrical Engineering, 1960
A NEW TYPE of excitation system has been developed for use in the electric utility industry in which the generator collector and collector brushes, and the exciter commutator and commutator brushes are eliminated. The basic difference between this system and its predecessors is an a-c exciter mounted on the same shaft as the generator field.
