Title (EN) INJECTED-CAGE ROTOR
(FR) ROTOR A CAGE INJECTEE
Abstract:
(EN) The rotor of a rotary electric machine, comprising: – a bundle of magnetic laminations defining slots each having first and second opposite long sides, oriented substantially radially, – bars (10) of a first electrically conducting material housed in the slots, occupying just a portion of the cross section of the slots and each coming to bear, over at least part of their length, on just one of the said long sides at a time, leaving a space to the opposite face, and – a second electrically conducting material, different from the first, injected into the slots and present in the said space.
(FR) Rotor de machine électrique tournante comportant : - un paquet de tôles magnétiques définissant des encoches présentant chacune des premier et deuxième grands côtés opposés, orientés sensiblement radialement, - des barres (10) d'un premier matériau électriquement conducteur reçues dans les encoches, occupant seulement une portion de la section des encoches et venant chacune en appui pour au moins une partie de leur longueur sur un seul desdits grands côtés à la fois, ménageant avec la face opposée un espace, et - un deuxième matériau électriquement conducteur, différent du premier, injecté dans les encoches et présent dans ledit espace.
