Diseño y construcción de un equipo para diagnóstico de las bobinas del estator para MG de vehículos híbridos

Abstract

This work aimed to design and build the diagnostic equipment for the stator coils for mg of hybrid vehicles. It set a proposal to the problem of a better quality of maintenance, due to the lack of diagnostic equipment and machines. The preliminary design of the external structure of the equipment was carried out through the program of design aided by SOLIDWORKS computer. The programming of the circuit was achieved through the calculation and determination of variables. And based on the graphical interpretation of the inductance as a function of the frequency variation by AC voltage supply. A formula was derived inversely proportional through mathematical calculations to inductance concerning frequency variation at different levels to obtain a more detailed behavior of the curve. The operation of the equipment by deriving each measurement with a winding respectively. It started in sequence, U-V; U-W; V-W. Therefore, it was obtained three readings, interpreted in a graphical way which used dispersion to be able to have a trend line. In this case in the three curves, a very acceptable similarity was observed between winding one and three, there was a variation mainly due to the manufacture of electronic materials. Therefore, they tend to have a random variation in each measurement. Using the graphs obtained in test one of a single coil and the graphs in test two of all coils. All these graphs are partially similar to each other. It is possible to say that all the data obtained are following the conditions of the team's functioning. It is recommended to carry out the tests and the data collection of the windings without the stator, as this will generate a magnetic field.
