Abstract

resumo “elevador com eletroímãs permanentes” um elevador com eletroímãs permanentes compreendendo uma estrutura de mancal externa (2, 3,) fechada no fundo por uma placa fornecida com uma blindagem de calor (9), a partir da qual os pólos de circuito (1) se projetam com suas peças de pólo (5), cada um dos eletroímãs permanentes sendo compostos de um ímã reversível (6) disposto no topo de um dos ditos pólos (1), de um ímã de polarização fixa (7) formado por vários blocos colocados ao longo das faces laterais do dito pólo (1), e de uma bobina (8) disposta em torno do dito ímã reversível (6) para causar a inversão da polarização do último por meio de um pulso elétrico, o ímã de polarização fixa (7) sendo feito de uma liga de samário-cobalto que tem um ponto de curie de cerca de 770°c e um campo coercivo residual capaz de resistir ao dito pulso de polarização inversa do ímã reversível (6) mesmo quando o elevador opera em materiais em 600 – 650°c.
