Title (EN) SQUIRREL-CAGE ROTOR
(FR) ROTOR A CAGE INJECTEE
Abstract:
(EN) Rotor for an electric rotating machine, comprising: - a bundle of magnetic sheets (113) having notches therethrough, the sheets being produced by punching using a press die applied to a first face (113a) of the sheets towards a second face (113b) opposite to the first, - bars of a first electrically conductive material received in the notches, - a second electrically conductive material, different from the first material, injected into the notches, the bundle of sheets comprising sheets, the first faces (113a) or the second faces (113b) of which are arranged facing one another, so as to generate on the bars a shear to ensure that the sheets are held before the second material is injected.
(FR) Rotor de machine tournante électrique, comportant : - un paquet de tôles magnétiques (113) traversé par des encoches, les tôles étant réalisées par découpage par un poinçon s'appliquant sur une première face (113a) des tôles en direction d'une deuxième face (113b) opposée à la première, - des barres d'un premier matériau électriquement conducteur reçues dans les encoches, - un deuxième matériau électriquement conducteur, différent du premier matériau, injecté dans les encoches, le paquet de tôles comportant des tôles dont les premières faces (113a) ou les deuxièmes faces (113b) sont disposées en regard l'une de l'autre, de façon à générer sur les barres un cisaillement assurant leur maintien avant l'injection du deuxième matériau.
