Abstract

"MáQUINA ELéTRICA DE COMUTAçãO DE FLUXO". Um máquina elétrica de comutação de fluxo tem um estator (1) e um rotor (2). O rotor que comporta meios para estabelecer circuitos magnáticos fechados que passam em volta das hastes dos enrolamentos de estator. De acordo com a invenção. esses meios comportam ímãs permanentes de excitação (255) que engedram um fluxo magnético que se encarola circunferencialmente sobre si mesmo, e enrolamentos de excitação (1215,216) estabelecendo localmente um fluxo regulável em uma direção inversa á do fluxo produzido pelos ímãs; cada ímã é alojado em uma primeira parte de rotor (22) que definem um primeiro par de pólos, e os enrolamentoas são colocados em volta de uma segunda parte do rotor (21), cujas extremidades definem um segundo par de pólos; o rotor tem entre as primeira e segunda partes adjacentes terceiras partes (23) que formam com as primeiras e segundas um trajeto de condução magnética circunferencial.
