Abstract

MáQUINA SìNCRONA E PROCESSO DE FABRICAçãO DE MáQUINA SìNCRONA. A presente invenção refere-se a uma máquina síncrona e a um processo de fabricação de uma máquina síncrona e, mais particularmente a uma máquina síncrona que possui ímas permanentes (22) dentro do rotor (10), tendo-se como objetivos uma máquina elétrica onde se reduza o vaza- mento do fluxo magnético gerado pelos ímas, e tendo também características construtivas que maximizem a diferença nas relutâncias de eixo direto (32) e eixo em quadratura (31) e, ao mesmo tempo se obtenha um rotor com a resistência mecânica necessária para o bom funcionamento do equipamento. Tais objetivos são alcançados através de uma máquina síncrona onde as ranhuras de fixação de ímãs (20) do rotor (10) são providas de extremidades alongadas (101,102,103) configuradas, de modo a formar canais de majoramento de relutância (50,60,80), uma primeira extremidade alongada (101) prolongando-se desde a primeira porção extrema livre (25) até uma região adjacente á extremidade do fundo de ranhura do rotor (15), a primeira extremidade alongada (101) sendo configurada a partir de uma abertura no rotor (10), formando canais de majoramento de relutância (50), a abertura prolongando-se ao longo do rotor (10) e ao longo da ranhura de fixação (20), uma segunda extremidade alongada (102) das ranhuras de fixação sendo configurada de modo a formar o canal de majoramento de relutância (60, 80) e prolonga-se a partir da respectiva segunda porção extrema livre (26) em direção a segunda porção extrema livre (26) da outra ranhura de fixação (20) do par. é ainda descrito um processo de fabricação de uma máquina síncrona.
