Abstract

L'invention concerne un générateur à moteur diesel silencieux numérique de petites dimensions utilisé dans un dispositif mécanique et électrique servant d'alimentation électrique extérieure et de source électrique d'appoint. Le générateur à aimant permanent est fixé au moteur, sa caractéristique étant que le silencieux est recouvert d'un boîtier, le filtre à air est solidaire d'un couvercle de guidage de vent, la plaque de guidage de vent supérieure, la plaque de guidage de vent latérale et la plaque de guidage de vent inférieure étant utilisés pour entourer la culasse de cylindre et le carter d'huile pour former séparément deux chambres de ventilation principales. La batterie et le modulaire d'inversion sont tous deux fixés en juxtaposition devant le couvercle de guidage de vent. Le châssis du générateur est fixé à la base, servant ensuite à fixer les couvercles avant et arrière. La tension de sortie se stabilise grâce à la technique d'inversion. L'ordre de sortie est envoyé par le modulaire d'inversion et le papillon est régulé par le moteur pas à pas, de sorte que le générateur fonctionne économiquement sur de l'énergie.
