Abstract

Patente de Invenção: "ROTOR PARA UMA MáQUINA ELéTRICADE ALTA ROTAçãO". é indicado um rotor para uma máquinaelétrica de alta rotação, o qual é constituído por uma pilha de umgrande número de discos maciços (1) espessos enfileiradosaxialmente, sendo que em suas superfícies frontais, os discosmaciços (1) apresentam uma superfície de prensagem (5) definidae pelo fato de que, na área das superfícies de prensagem (5) apilha é atravessada por barras de tração (2) na direção axial.Nesse caso, as barras de tração (2) pressionam os discos maciços(1) um contra o outro nas superfícies de prensagem (5). Além disso,para a economia de peso e de material, está prevista umareentrância (8) central e simétrica em relação à rotação delimitadana área de borda de cada um dos discos maciços (1) em, pelomenos, uma superfície frontal do disco maciço (1).
