Abstract

La invención se refiere a una máquina eléctrica, en particular un motor eléctrico, que comprende un rotor que tiene un paquete de láminas que comprende láminas apiladas (3a) que tienen al menos dos huecos que se extienden tangenciales, en cada uno de los cuales se acomoda en la mayor parte al menos un imán permanente (5), siendo que al menos una lámina (3a) tiene al menos un brazo elástico (6a) que se dispone entre los al menos dos imanes permanentes y colinda con un imán permanente (5) y actúa elásticamente contra este imán permanente sustancialmente en una dirección tangencial. El objeto de la presente invención es el de proporcionar una máquina eléctrica para la cual se hace más fácil el ensamble y eventual desensamble, se reduce el riesgo de la formación de viruta, se reduce el número de partes, resulta posible una fácil adaptación a diferentes geometrías y condiciones de uso, y se puede obtener una mejor eficiencia y una mayor densidad de potencia. Este problema se resuelve de conformidad con la invención mediante la parte distintiva de la reivindicación 1 y mediante el método de la reivindicación 19.
