Title (EN) A ROTOR FOR AN ELECTRICAL MACHINE
(FR) ROTOR POUR MACHINE ELECTRIQUE
Abstract:
(EN) A rotor (1) for an electric motor with permanent magnets (10) has a principal axis (D) , comprises a laminated core (2) delimited by a first and a second end wall (4, 5) and by a lateral surface (6) and has a hole (7) for coupling to a motor shaft (8) and a plurality of longitudinal slots (9) for housing the magnets (10) ; the rotor also comprises positioning devices (20) for stabilizing the magnets (10) in the slots (9) .
(FR) La présente invention concerne un rotor (1) pour un moteur électrique avec des aimants permanents (10). Ce rotor présente un axe principal (D), comprend un noyau feuilleté (2) délimité par une première paroi d'extrémité (4), par une seconde paroi d'extrémité (5) et par une surface latérale (6), et présente un orifice (7) conçu pour le couplage à un arbre de moteur (8), ainsi qu'une pluralité de fentes longitudinales (9) permettant de loger les aimants (10). Le rotor comprend également des dispositifs de positionnement (20) permettant de stabiliser les aimants (10) dans les fentes (9).
