Abstract

L'invention porte sur un système de génération d'énergie pour véhicule qui comprend une carcasse de bobine (31), un plateau rotatif magnétique (32), et un ensemble de réponse de vitesse (50). La carcasse de bobine (31) est fixée sur le véhicule (10) et comporte un groupe de bobines d'inductance (33). Le plateau rotatif magnétique (32) est agencé en relation avec le groupe de bobines d'inductance (33) avec un décalage et présente un champ magnétique. Un intervalle d'entrelacement de ligne de force magnétique existe entre le champ magnétique et le groupe de bobines d'inductance (33). L'ensemble de réponse de vitesse (50) est entraîné par une roue (12) pour amener le plateau rotatif magnétique (32) à tourner, de sorte que le champ magnétique est coupé par le groupe de bobines d'inductance (33) pour générer de l'énergie électrique. Lorsque la vitesse de rotation de la roue (12) change, le plateau rotatif magnétique (32) est décalé par l'ensemble de réponse de vitesse (50) afin de changer l'intervalle d'entrelacement de ligne de force magnétique, stabilisant ainsi l'énergie électrique générée par le groupe de bobines d'inductance (33).
