Abstract

Patente de Invenção: "MáQUINA ELéTRICA DE ALTA ROTAçãO". Uma máquina elétrica de alta rotação (10) compreende um rotor (11) montado rotativamente que, separado por um vão de ar (14), é circundado concentricamente por um estator (12) com duas espiras em projeção (18, 19), e compreende um meio (20,....29) para resfriar o rotor (11) e o estator (12), por meio do qual um meio de resfriamento, especialmente, ar de resfriamento, é enviado em um circuito pelo rotor (11) e estator (12), e o calor apreendido pelo meio de resfriamento ou o ar de resfriamento no processo é reextraído em um resfriador (20). Em tal máquina, obtém-se um resfriamento aperfeiçoado e de custo mais efetivo pelo meio de resfriamento, ou o ar de resfriamento é dirigido em dois circuitos de resfriamento, primeiro e segundo, de preferência, em paralelo, bastante mutuamente independentes (24 e 25) para o estator (12) e o rotor (11).
