Title (EN) SQUIRREL-CAGE ROTOR
(FR) ROTOR A CAGE INJECTEE
Abstract:
(EN) The invention relates to the rotor of a rotating electrical machine, comprising: a stack (2) of magnetic laminations (113) defining slots (4); bars (10) of a first electrically conductive material, received in the slots (4); a second electrically conductive material (20), different from the first, injected into the slots (4); and pins (70) or rivets inserted into the slots (4) in contact with the bars (10).
(FR) Rotor de machine tournante électrique, comportant un paquet (2) de tôles magnétiques (113) définissant des encoches (4), des barres (10) d'un premier matériau conducteur électrique reçues dans les encoches (4), un deuxième matériau (20) électriquement conducteur, différent du premier, injecté dans les encoches (4), des goupilles (70) ou rivets insérés dans les encoches (4) au contact des barres (10).
