Abstract

Perfeccionamientos introducidos en una máquina dinamoeléctrica superconductora del tipo de generador o motor sincrono, que comprende un bastidor o armazón que encierra un estator en el que se tiene un devanado, y un rotor que soporta un devanado superconductor de campo de corriente continua dispuesto para girar en dicho estator, unos medios para soportar dicho rotor en unos cojinetes dispuestos en dicho bastidor, incluyendo dicho rotor un miembro cilíndrico que encierra por completo dicho devanado de campo, habiendo en dicho miembro cilíndrico unos medios que sostienen el devanado de campo, siendo estos medios de una resistencia estructural suficiente para absorber los esfuerzos de par aplicados a dicho rotor durante el funcionamiento, habiendo en dicho miembro cilíndrico también unos medios de pantalla de radiación para absorber la radiación térmica procedente de los miembros estructurales que operen a una temperatura sustancialmente igual a la del ambiente, incluyendo dicho miembro cilíndrico unos medios de pantalla de amortiguamiento que contienen un líquido eléctricamente conductor que tiene por efecto el de restablecer el par o momento en el rotor al varia el sistema de carga, y el de apantallar o proteger el devanado superconductor de campo respecto de los campos de corriente alterna engendrados en el estator durante el funcionamiento y habiendo en dicho árbol unos medios para suministrar corriente eléctrica de excitación a dicho devanado y unos medios de refrigeración asociados a dicha máquina para suministrar un refrigerante fluido a dicho rotor de tal modo que el devanado de campo se mantenga aproximadamente a 4,2 K
