Abstract

Many practical applications are predicted for superconducting dc motors and generators. This article presents the simple theory of operations and loss mechanisms of the dc generator, and discusses methods for minimizing these losses Most of today's superconducting dc generators were designed for energizing large superconducting electromagnet systems, for energizing multiple concentric-coil magnets by single pumps, and for energizing tuning magnets by a system having adjustable tuning control.1–5 The chief advantage of the dc generator is the avoidance of the large input leads that would be required to carry heavy currents from external sources to superconducting devices. Because these leads can produce high heat losses, the problem becomes more significant as superconducting wires having higher current-carrying capacities are developed.
