The invention is an aircraft power generation system which utilizes an induction-machine (G1) as a primary generator of variable-voltage/variable-frequency power. The induction-machine (G1) is directly driven by the engine (14) and is excited by an excitation-generator (G2) such that the induction-machine (G1) operates in a generating mode. A variable-speed drive (20), shown as a toroidal drive (30), controls the excitation frequency of the induction-machine (G1) such that the negative slip-frequency is controlled as a function of the input speeds (N1), ...
A power generating system comprising: an induction machine including an induction rotor and a stator; mechanical drive means connected to said induction motor for driving said induction machine at a variable speed; a synchronous excitation generator coupled mechanically with said induction machine by means of a variable-speed drive, whereby said synchronous excitation generator will provide a variable output voltage and frequency; means for applying said variable output voltage and frequency to said stator of said induction machine; and drive-logic contr...
