Otimização de um regenerador de energia eletromagnética

Abstract

The technological improvement increases the demand for energetic sources, which can cause high economics and environments impacts when randomly used. A big economic investment is necessary due to the amount of energy needed, this also negatively impacts the environment, as new power plants will be built. Therefore, a main society worry is the rational use of energetic sources, so new researches outcome to automatize electric systems and harvesters, also known as energy collectors, are one of the most studied ones, they convert one of the unused energies of the systems in an electrical energy. Using the Faraday principles, one of the technics of harvesters applications is due to the conversion of a vibration system into electric-magnetic energy. A vibrating permanent magnet creates a differential in the magnetic field of a coil, which produces an induced current and consequently electric energy, this will be the object of study during this work. Willing to optimize this vibration system into a remote monitoring sensor produced by the university, therefore, the parameter to optimize the vibration will be the model stiffness. Finally, an optimum rigidity for the vibration system can be achieved, the optimizer to work correctly and observing the desired system behavior.
