Patent ID: 7064455

Claim:
Fixed frequency electrical generation system that can be placed at the variable load engine output, characterised in that it includes: an initial stage ( 30 ), which is a permanent magnet generator that provides energy to said system, making it autonomous, a secondary stage ( 21 ), which is an excitation stage that controls the magnetisation of a third stage, this third stage ( 24 ), which is a main generator, is the electrical energy production power stage, in that the rotors ( 22 and 25 ) of the secondary stage ( 21 ) and the third stage ( 24 ) are integrated into a first shaft ( 27 ), the stator ( 26 ) of the third stage ( 24 ) supplies the output voltage (V sm ), in that the rotor ( 31 ) of the first stage ( 30 ) is integrated into a second shaft ( 33 ), in that at least one oil pump of the cooling circuit ( 34 ) is integrated into a third shaft ( 35 ), and in that these three shafts ( 27 , 33 , and 35 ) are driven by the input shaft ( 36 ), which is the engine shaft, using gears ( 37 , 38 , 39 , and 40 ).
