Title (EN) SQUIRREL-CAGE ROTOR
(FR) ROTOR A CAGE INJECTEE
Abstract:
(EN) The invention relates to a rotor for a rotary electrical machine, comprising: - a packet (2) of magnetic sheets comprising notches (4) formed by holes of the magnetic sheets (2), separating raised patterns extending inside the holes and separating the notches (4) into first and second separate compartments, the first compartments being radially inside the second compartments, - a first conductive material being arranged in the first compartments of at least one portion of the notches (4), - a second electrically conductive material, other than the first, being arranged in the second compartments (8) of these notches (4), the separating raised patterns which extend inside the holes preventing the first and second materials from coming into contact.
(FR) Rotor pour machine électrique tournante, comportant : - un paquet (2) de tôles magnétiques comportant des encoches (4) formées par des ajours des tôles magnétiques (2), des reliefs de séparation s'étendant au sein des ajours et séparant les encoches (4) en des premiers et deuxièmes compartiments distincts, les premiers compartiments étant radialement intérieurs aux seconds compartiments, - un premier matériau conducteur étant disposé dans les premiers compartiments d'une partie au moins des encoches (4), - un deuxième matériau électriquement conducteur, différent du premier, étant disposé dans les deuxièmes compartiments (8) de ces encoches (4), les reliefs de séparation qui s'étendent au sein des ajours empêchant les premier et deuxième matériaux de venir en contact.
