Abstract

MANCAL HIDRODINáMICO ATIVO COM SAPATAS MóVEIS MAGNéTICAS. A presente invenção combina a capacidade de carga de mancais hidrodinâmicos de sapatas móveis com a capacidade de atuação dos atuadores eletromagnéticos, de forma a se poder alterar ativamente as características dinâmicas de máquinas rotativas. Atuadores eletromagnéticos (3) são inseridos nas sapatas móveis do mancal hidrodinâmico, formando pares nas direções ortogonais ao rotor/eixo (9). Desta forma, tem-se um sistema de atuação compacto para sistemas rotativos. Sensores de proximidade (34a,34b) medem os deslocamentos do rotor/eixo (9) e seus sinais são processados em malha de realimentação (sistema de controle) e enviados para os atuadores eletromagnéticos (3) presentes nas sapatas do mancal hidrodinâmico. As forças eletromagnéticas dos atuadores atuam no rotor/eixo (9), controlando seus movimentos e alterando as características dinâmicas do sistema rotativo.
