Title (EN) SQUIRREL-CAGE ROTOR
(FR) ROTOR A CAGE INJECTEE
Abstract:
(EN) A rotor of a rotating electrical machine, comprising : - a stack of magnetic laminations, the magnetic laminations having cut-outs forming, within the stack, n main notches (4) and m secondary notches (40), radially inwards with respect to the main notches (4), with n and m being non-zero integers and n > m; - bars (10) of a first electrically conductive material in at least one portion of the main notches; and - a second electrically conductive material (20), different from the first, injected into the secondary notches (40).
(FR) Rotor de machine électrique tournante, comportant : - un paquet de tôles magnétiques, les tôles magnétiques comportant des ajours formant au sein du paquet n encoches principales (4) et m encoches secondaires (40), radialement intérieures par rapport aux encoches principales (4), avec n et m entiers non nuls et n>m, - des barres (10) d'un premier matériau conducteur électrique dans au moins une partie des encoches principales, - un deuxième matériau (20) conducteur électrique, différent du premier, injecté dans les encoches secondaires (40).
