Abstract

Patente de Invenção: <B>"APOIO DE ROTORES DE GERADORES NO CAMPO MAGNéTICO"<D>. A presente invenção refere-se a um equipamento para o apoio de rotores de geradores, em particular hidrogeradores, no campo magnético. Neste caso, o apoio se dá através de ao menos um mancal magnético, o qual é disposto na região da coroa de rotor e dos enrolamentos de pólo. Assim, se dá uma derivação da força de peso do rotor diretamente no local de produção. O ao menos um mancal magnético pode consistir ou de um mancal radial separado e de um mancal axial separado ou de uma combinação de mancais radiais e axiais. O ao menos um mancal magnético pode ser disposto tanto acima como também abaixo do rotor e conduz a força de peso para a fundação. Por meio da utilização de mancais magnéticos se dá, em virtude de uma redução de perdas nos mancais, uma elevação do grau e ação total. Além disto, o rotor pode ser configurado livre, a compacticidade até agora necessária não é mais incondicionalmente necessária.
