Patent

CA 2646041

An aircraft starting and generating system includes a starter/generator that includes a main machine, an exciter, and a permanent magnet generator. The system also includes an inverter/converter/controller that is connected to the starter/generator and that generates AC power to drive the starter/generator in a start mode for starting a prime mover of the aircraft, and that converts AC power, obtained from the starter/generator after the prime mover have been started, to DC power in a generate mode of the starter/generator. The exciter includes a stator and a rotor, and wherein the exciter rotor includes a three-phase AC winding.

Un système démarreur et générateur de moteur d'avion comprend un géné-démarreur qui comprend un moteur principal, un excitateur et un générateur à aimant permanent. Le système comprend également un inverseur/convertisseur/contrôleur qui est connecté au géné-démarreur et qui génère un courant alternatif pour entraîner le géné-démarreur en mode démarreur pour le démarrage d'un moteur d'entraînement de l'avion, et qui convertit la courant alternatif obtenu par le géné-démarreur une fois que le moteur d'entraînement a été lancé, en courant continu en mode générateur du géné-démarreur. L'excitateur comprend un stator et un rotor, le rotor excitateur comprenant un enroulement courant alternatif triphasé.
