Abstract
Development of new types of electrical machines with cryogenic cooling and superconducting windings is to be based on application of new materials and new technological processes. The superconducting field winding impregnation epoxies are to withstand a long-term operation with thermocycling, and the main coil insulation is to withstand overvoltages during the transitions and to provide adequate cooling at operating modes, including the excitation current variations. The slotless stator developments are being based on introduction of new stator winding geometries and technological processes. Development of superconducting and hyperconducting armature windings, operating at relatively high electrical voltages must be associated with the investigation of the problem of electrical insulation ageing. The results of practical experience with superconducting alternators and experimental investigation of the models are being presented.
