- Resumen
The development of new technologies of superconductor electrical machines in axial flow configuration has been one of the areas of investigation of DEE of ETSEIB - UPC.
In this work a revision becomes of the state-of-the-art of conventional the electrical motors of axial flow and an application in superconductive machines becomes of the same A series of models of motors of axial flow of 4, 6 and 8 poles, was made, designed and constructed with base to the main parameters of the design of this type of machines, that they are the Internal Diameter (Di) and the External Diameter (DO) with a geometry of bilateral stator (the rotor in the middle of two semi-stators), and sets out a new alternative of rotors for this type of motors, in one forms of ""flat squirrel cage.
A study becomes on rotors of disc of Al, in where different factors are determined that affect the magnetic coupling between the rotor and the stator, as it is the number of The designed stators and rotors are constructed with superconductive tapes of high temperature of composition BSCCO-2223, in where are different aspects from the relation of the critical current of the superconducting one with respect to the number of welded An evaluation becomes of the behaviour of the ferromagnetic material to 300 K and 77 K and tests of their effect in the performance of the motor are made. The evaluations were made on the basis of determining the speed-current relation of each one of the configurations and the characteristics of design for the superconducting motors in configuration of axial flow were determined.
The obtained final results in this thesis, which can be used for future designs of electrical machines in configuration of axial flow are: ¿ Application of superconductive tapes HTS in the rotor and the stator ¿ Relation of diameters of the motor ¿ Number of slots/pole in the estator ¿ Optimal number of tape bars HTS in the rotor ¿ Use of ferromagnetic material in the superconducting motor.
