Abstract
Abstract
Compared to traditional machines, superconducting electrical machines have significant advantages, i.e: improved weight and dimensions, higher efficiency, lower values of inductive parameters, reduced noise level, greater stability when operating in electrical networks. Development of such machines requires the solution of a whole series of scientific and engineering problems related to many fields of science and technology. Along with the solution of traditional problems of the usual “warm” electrical engineering, one has to solve the problems associated with cooling of superconducting windings and the stability of their superconducting state under the action of external heat leakage, centrifugal and ponderomotive forces, as well as vibrations. The design of cryogenic machines should provide for the compensation of thermal compression of structural elements and windings during cooling process. This paper presents some interdisciplinary tasks, the solution of which will allow to reach a new level in the field of superconducting electrical machines and to create samples of electric motors and generators, surpassing all existing analogues in specific parameters.
