Abstract

"UNIDADE DE COMPRESSOR COMPREENDENDO UM COMPRESSOR CENTRìFUGO E UM MOTOR ELéTRICO". A presente invenção refere-se a uma unidade do compressor compreende um compressor centrífugo (1) para comprimir um gás, tendo um rotor (2) com um ou mais impulsores de compressor (3), e um motor elétrico (4) tendo um estator (5) e um rotor (6), para acionar o rotor (2) do compressor. O compressor e o motor elétrico são acomodados em um alojamento comum impermeável ao gás (7) que é proporcionado com uma entrada de gás (8) e uma saída de gás (9). O rotor do compressor e o rotor do motor elétrico são dispostos em um eixo comum do rotor (10) o qual é montado em mancais magnéticos (11, 12, 15). O eixo do rotor (10) compreende uma unidade única e é montado em dois mancais magnéticos radiais (11, 12), cada um na adjacência de uma extremidade do eixo comum do rotor, e um mancal magnético axial (15), que é disposto na adjacência de um (11) dos mancais radiais.
