Abstract

La présente invention concerne un générateur d'énergie électrique comprenant un rotor et une pluralité de stators disposés de manière coaxiale et concentrique autour d'un axe central. Un premier stator est disposé de manière concentrique autour du rotor et adjacent au rotor, le rotor et le premier stator étant séparés par un entrefer rotor-stator et un second stator est disposé de manière concentrique autour du premier stator et adjacent au premier stator, les premier et second stators étant séparés par un entrefer stator-stator. Le rotor comprend une pluralité de structures de pôles magnétiques configurées pour fournir ou générer une pluralité de pôles magnétiques et une surface radialement externe de chacune des structures de pôles magnétiques est incurvée avec un rayon de courbure moyen qui est inférieur à une distance moyenne entre la surface extérieure et l'axe central. L'entrefer rotor-stator varie ainsi en distance de manière circonférentielle, la distance la plus courte étant au centre circonférentiel de chacune des structures de pôle magnétique et la distance la plus longue étant aux extrémités circonférentielles de chacune des structures de pôles magnétiques. L'entrefer stator-stator est d'épaisseur uniforme.
