Abstract

ROTOR PARA UMA MáQUINA ELéTRICA. A presente invenção refere-se a um rotor para uma máquina elétrica (2) formado de folhas em camadas (5, 22) essencialmente perpendioulares ao eixo geométrico de rotação do rotor. De acordo com a invenção, o rotor compreende pelo menos um primeiro feixe de folhas (4) que está localizado próximo ao eixo geométrico central da revolução do rotor e tem cavidades essencialmente iguais em largura aos póíos de rotor sobre o lado da circunferência do rotor, e pelo menos um segundo feixe de folhas (20) que é montado na cavidade no primeiro feixe de folhas e essencialmente se estende para a circunferência do rotor, formando a superfície externa do pólo de rotor. Um espaço (21> se estendendo para a circunferência do rotor foi disposto entre o primeiro e o segundo feixe de folhas no interior do qual ímãs permanentes (26) propostos para a magnetização do motor são suscetíveis de serem montados.
