SYNCHRONOUS GENERATOR EXCITER Russian patent published in 2003 - IPC

FIELD: electrical engineering; power plants. SUBSTANCE: armature of exciter built integral with synchronous generator is made in the form of hollow current-conducting cylinder provided with two notches disposed in parallel with longitudinal axis and filled with dielectric material; armature is secured on butt-end of synchronous generator shaft and electrically insulated from the this shaft. One pole of magnetic core is disposed inside armature cylinder and other one encloses outer surface of armature cylinder so that air gaps are formed between cylinder and poles. EFFECT: enhanced reliability of generator excitation; simplified design of exciter armature. 1 cl, 1 dwg
