Abstract

L'invention concerne un générateur à rotor externe (10) pour voiture électrique disposé sur une roue menée d'une voiture électrique. Le générateur à rotor externe (10) comprend un stator interne (11) et un rotor externe (12). Le stator interne est relié fixement à un arbre mené (20) de la voiture électrique. Le rotor externe est relié à l'arbre mené de la voiture électrique de manière rotative et il est emmanché sur le stator interne. Plusieurs ensembles de bobines d'enroulement (31) sont disposés autour du stator interne. Une paroi interne du rotor externe est en outre munie de multiples aimants permanents (32) disposés uniformément selon un intervalle prédéfini. Lorsque le rotor externe tourne par rapport au stator interne, un mouvement d'interruption de la ligne d'induction magnétique se produit entre les bobines d'enroulement et les aimants permanents. Le générateur à rotor externe pour voiture électrique présente une structure simple et peut utiliser efficacement l'énergie cinétique résultant de la rotation rapide de la roue menée d'une voiture en mouvement pour générer de l'électricité, de manière à convertir raisonnablement l'énergie mécanique en énergie électrique.
