Abstract

sistema de ímãs permanentes para um rotor de uma máquina elétrica, sistema de ímãs permanentes para um rotor externo de uma máquina elétrica de rotor duplo, rotor de ímã permanente para uma máquina elétrica, rotor de ímã permanente externo para uma máquina elétrica de rotor duplo e ímã permanente curvilíneo axialmente magnetizado que tem um comprimento. trata-se de uma configuração de uma pluralidade de ímãs permanentes curvilíneos axialmente magnetizados alongados que têm alta razão de comprimento para seção transversal, produzida, por exemplo, processo de fabrica-ção pm-wire, que produz uma estrutura de rotor de ímã per-manente de máquina elétrica com um campo de desmagnetiza-ção intrínseco muito baixo, permitindo a operação em alta temperatura, em alta rpm ou viabilizando o uso de ímãs permanentes com campos de coercividade baixa. modalidades exemplificativas de configurações de ímã permanente de ro-tor de dois polos, quatro polos, seis polos e oito polos para aplicações de rotor duplo e simples. a nova configu-ração de ímãs permanentes curvilíneos axialmente magneti-zados reduz a desmagnetização em alta temperatura, aumenta a densidade de potência da máquina elétrica, reduz peso através da eliminação da necessidade de culatra, aumenta a confiabilidade de motor, reduz custos de fabricação e per-mite maior torque de motor elétrico e geradores elétricos. aplicações típicas dos ímãs permanentes curvilíneos axial-mente magnetizados, rotores e máquinas elétricas da inven-ção são em motores para veículos terrestres de alimentação elétrica, helicópteros, aviões e outra aeronave.
