Abstract

Patente de Invenção: <B>"ROTOR COM CURSO DE FLUXO SIMéTRICO PARA MáQUINAS ELéTRICAS"<D>. A invenção refere-se a um rotor (1) para máquinas elétricas, particularmente máquinas de relutância em ligação, com um eixo (15), com um induzido (12) e elementos de fixação (9). Pelos elementos de fixação (9) de acordo com o estado da técnica, em determinadas posições do rotor, é produzido um curso de fluxo assimétrico no rotor. A realização de acordo com a invenção, por distribuição simétrica dos elementos de fixação (9) e um determinado alinhamento dos elementos de fixação (9) aos pólos de rotor (5), leva a um curso de fluxo simétrico no rotor (1). Desse modo, o torque torna-se uniforme e a ondulação de torque é reduzida.Invention Patent: <B> "ROTOR WITH SYMMETRIC FLOW COURSE FOR ELECTRICAL MACHINES" <D>. The invention relates to a rotor (1) for electrical machines, particularly reluctance machines in connection, with an axis (15), with a armature (12) and fasteners (9). By means of the fastening elements (9) according to the state of the art, in certain positions of the rotor, an asymmetric flow path is produced in the rotor. The realization according to the invention, by symmetrical distribution of the fastening elements (9) and a certain alignment of the fastening elements (9) to the rotor poles (5), leads to a symmetrical flow path in the rotor (1). In this way, the torque becomes uniform and the torque ripple is reduced.
