Abstract

Rotor électrique. Ses roues sont réalisées en découpant dans une bande de fer 8 des éléments en forme de double crémaillère à dents opposées et comportant une fente 9. En déformant cette fente de manière à la transformer en un alésage polygonal l'élément découpé prend la forme d'une étoile dont on rabat les dents pour obtenir une des roues du rotor. Alternateur de faible puissanceElectric rotor. Its wheels are produced by cutting out from an iron strip 8 elements in the form of a double rack with opposite teeth and comprising a slot 9. By deforming this slot so as to transform it into a polygonal bore, the cut element takes the form of a star whose teeth are folded back to obtain one of the rotor wheels. Low power alternator
