Title
(DE) ROTOR EINES ELEKTROMOTORS
(EN) ROTOR OF AN ELECTRIC MOTOR
(FR) ROTOR D’UN MOTEUR ÉLECTRIQUE
Abstract
(DE) Die Erfindung betrifft ein Rotor (1) eines Elektromotors (2). Erfindungswesentlich ist dabei, - dass der Rotor (1) eine Grundwelle (3) aufweist, - dass an einer Außenmantelfläche (4) der Grundwelle (3) zumindest ein Blechpaket (5) angeordnet ist, - dass in dem zumindest einen Blechpaket (5) eine Ausnehmung (6) vorgesehen ist, in welcher ein Gewichtselement (7) zum Ausgleich einer Unwucht angeordnet ist. Hierdurch kann ein Rotor (1) geschaffen werden, der kostengünstig und einfach ausgewuchtet ist.
(EN) The invention relates to a rotor (1) of an electric motor (2). According to the invention: the rotor (1) has a main shaft (3); at least one laminated core (5) is located on an outer peripheral surface (4) of the main shaft (3); and a recess (6), in which a weight element (7) is located in order to compensate for an imbalance, is provided in the at least one laminated core (5). This makes it possible to create a rotor (1) that is balanced inexpensively and simply.
(FR) L'invention concerne un rotor (1) d’un moteur électrique (2). L’invention est caractérisée en ce que : le rotor (1) présente un arbre de base (3) ; une surface d'enveloppe extérieure (4) de l'arbre de base (3) comporte au moins un paquet de tôles (5) ; et le ou les paquets de tôles (5) présentent un évidement (6) dans lequel est disposé un élément de poids (7) servant à compenser un balourd. Il est ainsi possible de créer un rotor (1) économique et simple à équilibrer.
