Abstract

"MáQUINA ELéTRICA". Um máquina elétrica possui um estator (1) e um motor (2), o estator possuindo pelo menos uma bobina de induzido (14) alojada em pelo menos uma par de entalhes (13), o rotor possuindo meios apropriados para seletivamente estabelecer circuitos magnéticos fechados que passam em volta dos filamentos da ou das bobinas do induzido. De acordo com a invenção, os ditos meios possuem pelo menos dois ímãs permanentes de excitações (27) apropriados para estabelecer dois fluxos magnéticos que têm de acordo com a direção de deslocamento do rotor dos componentes sentidos opostos, e, entre cada par de ímãs sucessivos, pelo menos uma bobina de excitação que possui dois filamentos e é apropriada para gerar de modo regulável dois componentes de fluxo apropriados para se opor aos fluxos gerados nos ímãs do dito par, os filamentos de bobinas sendo alojados em entalhes que se estendem cada um deles entre dois pólos sucessivos de rotor. Aplicação notadamente aos alternadores de veículos automotores.
