Abstract

COMPENSACION DEL EFECTO DE LA TEMPERATURA EN UN RELE DE ADHERENCIA DE MAGNETISMO PERMANENTE Y ALTAMENTE SENSIBLE. EL RELE COMPRENDE UNA CULATA MAGNETICA (1 Y 2) CON IMANES PERMANENTES (7) FIJADOS SOBRE LA MISMA, UNA ARMADURA (4) DISPUESTA SOBRE LAS PATILLAS DE LA CULATA MAGETICA Y TENSADA POR UN RESORTE (5) Y UNA BOBINA (6) QUE RODEA UNA DE LAS PATILLAS DE LA CULATA MAGNETICA. PARA COMPENSAR LA TEMPERATURA E INFLUIR SOBRE EL FLUJO DE ADHERENCIA MAGNETICO, EN CASO DE QUE INFLUYA LA TEMPERATURA, EXISTE UNA RESISTENCIA MAGNETICA (8) CON COEFICIENTE POSITIVO DE TEMPERATURA.
