Abstract

La présente invention concerne un générateur homopolaire pour un dispositif de production d'énergie électrique. Le générateur fait notamment partie d'une éolienne ou d'une centrale hydroélectrique et est directement entraîné par les pales de l'éolienne ou de la centrale hydroélectrique, c'est-à-dire sans transmission intermédiaire. Une bobine supraconductrice qui est découplée mécaniquement du rotor, c'est-à-dire qui ne tourne pas conjointement au rotor, produit un flux magnétique qui est conduit par le rotor de manière à traverser l'enroulement d'un stator en direction radiale. Le rotor présente à cette fin des sections qui entourent le stator à la manière de griffes, lesquelles sections conduisent le flux magnétique. Des pôles conduisant le flux magnétique se trouvent sur lesdites sections du rotor, lesquels pôles permettent de faire varier le flux magnétique lorsque l'on observe dans la direction périphérique du stator. Une tension est induite dans les enroulements du stator lorsque le champ magnétique est constant et que le rotor tourne. Le rotor tourne de préférence à une fréquence constante. Il est possible d'adapter la fréquence de sortie du générateur à la fréquence du réseau grâce à un choix correspondant du nombre de pôles.
