UTILIZAÇÃO DE SUPERCONDUTORES EM MÁQUINAS E MOTORES: aplicação e viabilidade

Abstract

This term paper intends to introduce the use of the superconductor on electric machines and motors. The use of this technology significantly reduces the electrical losses on the energy conduction and the system has efficiency gains and are more stable, compact and light. On the other side, this material is associated to cryogenic systems (refrigeration systems), which raises the total cost and consumes a part of the power to allow the flow of the refrigeration fluid. It is going to be analyzed the economic viability of this technology use, taking into consideration the local infrastructure conditions of installation and the increase of the energy efficiency compared to the costs of the system. For this, it is going to be studied how to put the conductor in the superconductor state, what are the utilized materials, as well as a historic of these material discovery. It’s going to be seen the best situations of the use of superconductor motors and machines and the presentation of its characteristics. From these information, it’s going to be shown that this technology raises these equipment quality and price, and in specific applications it may turn into a great alternative. In the moment the technology is being developed mostly on the wind power segment.
