Abstract

ROTOR PARA UMA MÁQUINA ELÉTRICA DE ÍMÃ PERMANENTE. A presente invenção refere-se a um rotor (4) para uma máquina elétrica excitada por ímãs permanentes, o dito rotor compreendendo o corpo magnético substancialmente cilíndrico do rotor adaptado no eixo da máquina elétrica e um conjunto de ímãs permanentes (18, 20) usando para criar um primeiro e um segundo pólo alternadamente na direção circunferencial, excitados em direções opostas (N, S). Os ímãs permanentes são adaptados nas aberturas (12, 14) dispostas dentro do rotor.O rotor compreende uma parte de corpo (28) com diversos segmentos (24) que se estendem para a circunferência externa na direção circunferencial e uma seção afunilada para fora (26) que permanece entre os segmentos na direção radial do rotor. As peças de ímã permanente (18,20) são dispostas entre cada seção (26) e segmento (24).
