Abstract

máquina síncrona de ímã permantente e um método para fabricação e instalação da mesma. a presente invenção refere-se a uma máquina síncrona de ímã permanente com um estator (14) e um rotor (12) localizado a uma distância do espaço de ar (<sym>) do estador. o rotor é suportado no eixo em um arranjo rotativo, e um valor máximo foi determinado para a excentricidade entre o estator e o rotor. o valor é mais alto do que um décimo do espaço de ar. a magnetização da máquina síncrona é disposta com ímã permanentes adaptados no rotor (12) para a criação de um fluxo magnético (<sym>), o qual é fechado através do estator (14), do espaço de ar (<sym>) e do rotor (12). de acordo com a invenção, a relação h <sym> (10 <sym>) <sym> <109> se aplica entre a espessura do ímã permanente e o valor máximo de excentricidade <sym>. na relação, <sym> é o valor de dimensionamento do espaço de ar e <109> é a permeabilidade relativa do ímã permanente.
