Desarrollo de un generador lineal de imanes permanentes de baja potencia usando elementos finitos

Abstract

One of the main problems of linear generators is that due to the low speed of translation of their moving part, in order to generate large powers the machine must withstand great efforts which leads to very large devices, therefore, through the use of multiple Medium-power devices instead of a low number of high-power devices, a more suitable waveform is achieved for their integration into the network. In this article, two different linear generator topologies are proposed with characteristics obtained from a compilation of scientific literature, the parameters taken into account for the design and their respective modeling are presented through 2D simulations in COMSOL, as a contribution to the research project TOPOLOGIES OF LOW POWER WIND GENERATOR. The results obtained highlight the second of the proposed topologies, being the one with the best behavior under load, a cleaner terminal signal and greater power output in the face of variations in the magnitude of the load.
