Diseño e implementación de un banco de pruebas de alternadores, para la obtención de las curvas características de amperaje y voltaje y determinar su estado funcional

Abstract

The purpose of this degree work was the design and implementation of an alternator test bench to obtain the characteristic curves of amperage and voltage, determining its functional status through the technical diagnosis of the alternators. With the design of the structure, assembly of the mechanical, electrical, and electronic system, the test bench was implemented, to subsequently collect data from the alternators through the Lab VIEW software, this serves as an interface for the visualization of the graphs of the desired curves in real time, this was achieved thanks to the automation of the entire assembly, controlling the variables of current, voltage and revolutions, obtaining precise data for a better analysis. Several tests were carried out on some alternators with similar characteristics, the fidelity of said data was confirmed by comparing the computerized test reports of alternators with serial production and the data. It is concluded that the test bench works adequately by producing a graph similar to the curves of the series alternators. It is recommended that, for future implementations of alternator test benches, the designs support modifications in their control variables, since in this work they were not considered due to high execution costs.
