Abstract

''MáQUINA ELéTRICA''. Uma máquina elétrica compreende um estator (200) e um rotor (100). O estator compreende sobre sua face interna no mínimo um bobinado de induzido (213; 213a-213c) alojado no interior de um par de entalhes e uma série de alojamentos para meios de excitação. O rotor é desprovido de bobinado e compreende dentes (101) para estabelecer fluxos magnéticos variáveis no interior do induzido. A excitação põe em jogo imãs permanentes (214), aptos a estabelecer um fluxo magnético circunferencial fechado no estator e os bobinados de excitação (216) estabelecem localmente um fluxo magnético regulável na direção circunferencial inversa. De acordo com a invenção, os dentes do rotor são ajustados de maneira a efetuar ao nível do estator uma comutação de fluxo, e o ou cada imã permanente ocupa uma posição angular situada entre as posições angulares dos dois fios de um mesmo bobinado de induzido (213; 213a-213c). Gera-se assim, no ou nos bobinados de induzido, quando da rotação do rotor, um fluxo magnético alternativo. Aplicação nos alternadores sem escovas para veículos automotivos.
